‎Account of a Comet. - [THE DISCOVERY OF URANUS]‎

‎London, Lockyer Davis, and Peter Elmsly, 1782. 4to. In recent marbled paper wrappers. Extracted from ""Philosophical Transactions"", vol. 71, read April 26, 1781. Including title-page of volume. Leaves reinforced in margin. (2), V-VII, 492-501 pp. + three folded plates.‎


‎First edition of Herschel's seminal paper being the first recorded discovery of a new planet. Herschel's ""discovery [was] unprecedented in human history. [...] Herschel's ""new"" planet demonstrated that there is much more to the universe - even to our tiny solar system - than the eye can discern on its own."" (Lemonick, The Georgian Star).British astronomer William Herschel commenced ""his first review of the heavens, in which he examined stars down to the fourth magnitude. In August of that year he began a second review, more systematic and extensive than the first, and concentrated on the discovery of double stars"" (Dictionary of Scientific Biography)In March 1781, during his search for double stars, Herschel noticed an object appearing as a disk. Herschel originally thought it was a comet or a stellar disc, which he believed he might actually resolve. He reported the sighting to Nevil Maskelyne the Astronomer Royal. He made many more observations of it, and afterwards Russian Academician Anders Lexell computed the orbit and found it to be probably planetary. Herschel agreed, determining that it must be a planet beyond the orbit of Saturn. He called the new planet the ""Georgian star"" (Georgium sidus) after King George III, which also brought him favour"" the name did not hold. In France, where reference to the British king was to be avoided if possible, the planet was known as ""Herschel"" until the name ""Uranus"" was universally adopted. The same year, Herschel was awarded the Copley Medal and elected a Fellow of the Royal Society. In 1782, he was appointed ""The King's Astronomer"" (not to be confused with the Astronomer Royal).

(1821)

‎On the aberration of compound lenses and object-glasses. Read March 22, 1821.‎

‎London, W. Bulmer and W. Nicol, 1821. 4to. No wrappers as extracted from ""Philosophical Transactions"" 1821 - Part I. With titlepage to Part I. Pp. 222-267 a. 1 engraved plate. Verso of titlepage with 2 stamps.‎


‎First appearance of this importent paper in optical theory in which Herschel described how to free lenses from the aberration for two axis points, one of which is infinitely distant. It is known as Herschel's condition. ""Sir John Herschel gave the condition which must be satisfied in order that a symmetrical optical system, free from spherical aberration for two conjugate axial points, may also be free from spherical aberration for two neighbouring and conjugate points upon the axis of the system" but Herschel's condition applies only to first order aberration, i.e. to aberration depending upon the cube of the inclination of the ray to the axis. Abbe shewed, later, that this condition could be included in a wider result, viz. that the spherical aberration, supposed zero, is stationary for axial variations provided that the incident and emergent rays for two conjugate axial points, associated with modified magnification m, satisfy the relation.

‎On the Origin of Force. - [PRESENTATION-COPY - INSCRIBED FOR TYNDALL]‎

‎(London: Alexander Strahan and Company, 1868). 8vo. Without wrappers (as issued). Offprint, seperatly paginated, from ""Fortnightly Review 1"", Pp. 435-42. Author's presentation inscription to top of front wrapper: ""Prof Tyndall / With the author's / kind Compliments"". Soiling to front wrappers and nicks throughout, not affecting text. Internally clean. Pp. 8.‎


‎First edition, offprint, with the author's presentation inscription to Professor John Tyndall - the father of the Greenhouse Effect, heat radiation and global climate research - of this important paper, in which Herschel promotes the role of the devine in the natural order. Herschel, now famous for originating the use of the Julian day system in astronomy, naming seven moons of Saturn and four moons of Uranus, his investigation in colour blindness and the chemical power of ultraviolet rays, did much to promote the public understanding of science . The present paper constitutes one of his most widely read and popular works. ""During his life John was immensely celebrated, his name epitomizing science to the public, much as that of Einstein did in the next century."" (DSB)Though intended for a popular audience ""On the Origin of Force"" is one of the most important sources for understanding Herschel's general approach to science. A contemporary review of the paper states: ""The article is well worth reading for those who wish to realise the enormous benefit which has been rendered to science by banishing the indefinite uee of the word force and by introducing the term energy, restricting the use of force to the meaning attached to it by Newton. Sir John Herschel still speaks of the ""conservation of force"" (as did likewise Helmholtz, who, however, very early introduces the term Arheitskraft, power to do work, thus removing all ambiguity).Herschel and Tyndall corresponded throughout their mature lives and they shared an overall view on God's place in science. ""In the only case in which we are admitted into any personal knowledge of the origin of force, we find it connected (possibly by intermediate links untraceable by our faculties, but yet indubitably connected) with volition, and by inevitable consequence with motive, with intellect, and with all the attributes of mind in which-and not in the possession of arms, legs, brains, and viscera-personality consists."" (Herschel, rrom the present paper). Tyndall agreed in stating that: ""An inscrutable power of which we know no more than job did, when he said, 'Can man by searching find this power out?'. (Tyndall's ""Belfast Address"").‎

‎Description of a Forty-Feet Reflecting Telescope. - [HERSCHEL'S FAMOUS 40-FOOT TELESCOPE]‎

‎London, Peter Elmsly, 1795. 4to. In recent marbled paper wrappers. Extracted from ""Philosophical Transactions"". Including title-page of volume. Leaves reinforced in margin. Light offsetting from folded plates as usual. Plate depicting the full telescope with professional repair to lower right corner. (4), 347-410 pp. + 19 folded plates.‎


‎First appearance of William Herschel account of his great 40-foot telescope. It was the largest telescope in the world for 50 years and it was possibly used to discover Enceladus and Mimas, the 6th and 7th moons of Saturn. The plate of the 40-foot telescope fully assembled remains as one of the great icons of astronomy. ""It is well known that King George III granted £2,000 for the construction of the 40-foot reflector, and that this was supplemented by a further £2,000 plus other expenses. Only recently has it become evident that the second grant was made in the context of a serious row between monarch and astronomer. Herschel was of course in uncharted territory in attempting the construction of such a monster. The king had understood that the first £2,000 was the total required, and when this proved not to be the case he may well have suspected Herschel of deliberately underestimating the costs involved when making his original application. Although the king acceded-reluctantly-to the second request, from then on Herschel was required to account for every last penny of expenditure, and was told in no uncertain terms that no further grant would be forthcoming.The 40-foot reflector proved cumbersome and its results did not justify the labor and cost of its construction. What has only recently been appreciated is the extent to which it became a millstone around its creator's neck. From Herschel's point of view, it lost its principal raison d'être in 1790 when an observation with the 20-foot convinced him of the existence of ""true nebulosity."" But to the king it was an enduring symbol of his patronage of science, and visitors to Windsor Castle were invited to make the short journey to Slough to see the world's biggest telescope."" (DSB)‎

‎First appearance of a fundamental paper in cosmology and physics as it contains the first observational data to support that Newton's dynamical laws holds outside the solar system. Herschel shows here that the circulating motions of double-stars were under gravitational forces. Until then the validity of the law of gravity was only established within the solar system. Now, a century after the establishment of the law, it was traced out in the motion of incredibly distant stars and the theory first truly earned its title of Universal. The exact proof of the mutual gravitation of the double-stars was only obtained five years after Herschel's death, when the motions of the stars were more precisely dtermined.One of the most notable of Herschel's discoveries of double-stars, binary stars. A first cataloque of such pairs was published early in 1782 and contained 269, of which 227 were new discoveries. ""Twenty years after the publication of his first cataloque Herschel was of Michell's opinion - Michell had expressed the opinion that the odds in favour of a physical relation between the members of herschel's newly discovered double stars were ""beyond arithmetic"" - but was able to support it by evidence of an entirely novel and much more direct character. A series of observations of Castor, presented in two papers in the ""Philosophical Transaction"" in 1803 (the paper offered here) and 1804, which were fortunately supplemented by an observation of Bradley's in 1759, had shewn a progressive alteration in the direction of the line joining its two components, of such a character as to leave no doubt that the two stars were revolving round one another"" and there were five oher cases in which a similar motion was observed...it was shown that the double-star was really formed by a connected pair of stars near enough to influence one another's mortion.""(Berry in ""A Short History of Astronomy"" pp. 342-43).‎

He did, but in a rather unexpected way, for he found that the temperature rise was highest in no color at all, at a spot beyond the red end of the spectrum. He concluded that the sunlight contained invisible light beyond the red. This is now called infrared radiation.

""Were their apparent diameters as real as those of planets or spurious as for stars? To address this question Herschel conducted an extensive series of experiments in his garden in Slough, examining through his telescope small globules of differing sizes and materials placed in a tree some 800 ft (ca. 244 m) away (Herschel 1805). His observations showed that for the smallest globules the diameters were all spurious and all of the same size. Furthermore, he found that, if just the inner part of the aperture of the telescope were used, the spurious diameters, whether of globules or of stars, were larger. If the whole aperture was employed, the diameters were smaller, and if only an outer annular aperture was used the diameters were smaller still. This experimental discovery that unfilled apertures can be used to obtain high angular resolution remains today the essential basis for interferometric imaging in astronomy (in particular Aperture Masking Interferometry). The theoretical justification of this result came with Airy's analysis of the diffraction pattern of a circular aperture 30 years later (Airy 1835), and it took a further 30 years before the idea of using multiple apertures was developed. In an early study the Reverend W. R. Dawes noted that he had frequently found great advantage from the use of a perforated whole aperture' and that when observing Venus this produced a central image of the planet perfectly colourless, and very sharply dened' (Dawes 1866). But it was left to Fizeau, in his submission to the Commission for the Prix Bordin the following year, to remark on une relation remarquable et n´ecessaire entre la dimension des franges et celle de la source lumineuse' and suggest that by using an interferometric combination of light from two separated slits il deviendra possible d'obtenir quelques donn´ees nouvelles sur les diametres angulaires de ces astres' (Fizeau 1868).""‎

‎First appearance of a pioneer-paper in the history of early photography in which Herschel announced some of his importent discoveries of the photographic printing processes, the process of photographic contact-printing in Prussian blue, brought to light just three years after Louis Daguerre and Henry Talbot had announced their independent inventions of photography in silver, using metal and paper substrates, respectively. and the photographic properties of red ferro sesquicyanuret of potassium.""This is the first recorded observation of Prussian blue being formed for a photographic purpose by the action of light on potassium ferricyanide, so it represents the moment of discovery of the first cyanotype process, although this name still lay in the future. The significance of this observation impressed Herschel sufficiently to mention it also in his general diary entry for 23 April 1842....""(Mike Ware in ""John Herschel's Cyanotype.

Ignoring the explanation already given by Thomas Young wherby the rings result from interference between light waves, Herschel ceriticized Newton' theory and attempted one of his own. he brought down on his head a storm of criticism, and this may have been a cause of his poor health at this period.""(DSB VI, p.333).‎

‎First appearance of these highly influential papers as Herschel here reported the first observation of the fluorescence of a quinine solution in sunlight. - In a footnote to the report Herschel points out that he was writing from memory, having carried out the experiment more than twenty years before. Nevertheless, his reminiscence was enough to spark further exploration, eventually resulting in the modern understanding of fluorescence. In fact, even today, quinine is one of the most commonly utilized fluorophores for spectroscopy, enjoyed by many for the strange, but beautiful fluorescence that was first observed, but unable to be unexplained, by Herschel.‎
