Journal of the Indian Chemical Society January 1932

1932

The problem of the size weight and form of the atoms was now thrown into the background for lack of experimental data concerning them and the idea of a materia prima captivated the minds of later philosophers. [...] The annihiliation of matter according to the astro neimical evidence seems to be the only possible source of the energy radiated by the stars and thus constitutes one of the fundamental processes of the universe. [...] Salt formation through the action of acids upon metals such as silver nitrate from silver and nitric acid is according to Lemery an operation in which " the metal is penetrated and reduced to the form of salt by the points of the acid." It is thus seen that the believers in the corpuscular theory of matter regarded the form of corpuscles as the deciding factor in differen.+ic..ting different ki [...] The discovery of the Law of Isomorphism by E. Mitscherlich 4 in 1819 "Crystal form is independent of the chemical nature of atoms and is determined only by the number and relative position of the atoms" was of very great assistance in fixing the relative atomic weights of elements and thus gave great stimulus to the develop ment of the Atomic Theory. [...] With the object of testing the validity of Pasteur's Law as regards the equality in the numerical value of the rotatory power of the opposite active forms an extended series of investigations on the rotatory dispersion of enantiomorphous forms was undertaken in 1926.
