First printing of two paper's by father and son: Johann and Daniel Bernoulli. Daniel Bernoulli paper is a solution to the Riccati-equation: ""Using the first of the two transformations in [The Riccati-equation], Bernoulli succeded in constructing solutions of ""an inifinite number"" of Riccati equations for those values of n for which a solution can be expressed in finite terms. Bernoulli published these solutions in Acta Eruditorum for 1725 [the present paper]. (Greenberg. The problem of the earth's shape from Newton to Clairaut. P. 573).The offered volume contains many other papers by influential contemporary mathematicians, philosophers and historians.

First edition of these prize winning papers by father (Jean) and son (Daniel). - Both papers deals with the cause of the inclination of the planetary orbits relative to the solar equator. - In Daniel's paper he put foreward the hypothesis of the existence of an atmosphere, resempling air, and rotating around the solar axis, resulting in an increasing inclination of the planetary orbits toward the equator of the sun. Daniel was the first importent Newtonian outside Great Britain. The problems faced here (by Daniel) are treated in Newtonian manner.The publication of these papers by father and son resulted in a controversy between the two, forcing Daniel to leave his fathers house. - Poggendorff I:161.
