‎First appearance of a paper in which Crookes with his wide variety of apparatus tests Thores ""New Force"".""On february 15 last M.J. Thore communicated to a scientific society at Dax a short paper describing some results he had obtained on the rotation of a delicately suspended cylinder of ivory. So remarkable were these results that in a private letter to myself, accompanying a printed copy of his paper, Mr. Thore said ""they seem to demonstrate the existance of a new force inherent in the human organism."" (Crookes).Sir William Crookes (1832-1919) studied at the Royal College of Chemistry , London, and served there as an assistant to Hoffmann. In 1859 he founded the Chemical News and remained its proprietor and editor until his death. he early attracted attentuion by his discovery of the element thallium by spectroscopic methods. he was an active investigator in many fields of physics and contributed greatly to the advance of knowledge by his study of the radiometer and of the electric discharge in rarefied gases. -(PMM: 386 describing J.J.
