1938 13 43) has determined the parachors of some ammonium salts and of potassium chloride and iodide in aqueous solution and finds the value of parachor in each case to be less than the S[P] and is therefore of opinion that atomic parachor constants cannot be employed when the elements are in the ionic state. [...] In the case of sodium nitrate when the salt is dissolved there is a change in the volume directly proportional la the concentration and consequently the parachor has been calculated according to the Hammick and Andrew's equation and the final value deduced from a series of values of Ps by straight line extrapolation as shown in Fig. [...] The logarithmic curve thus indicates that in the case of alkali metals parachor is definitely connected with the fundamental property of the atom namely the atomic number or the nuclear charge. [...] BY K. GANAPATL in view of the recent discovery of the curative effects of sulphanilamide and many of its derivatives in the infections due to the coed and other bacteria it was thought worth while to prepare the gold salts of the allylthiourea derivatives of the above mefioned compounds for testing also in the case of tuberculosis. [...] Besides silica the following ions were detected in the ash: K Fe Ca Mg CI SO„ PO„ CO. In order to form an idea of the percentage and nature of the soluble portions of the drug a sample of the dried and crushed seeds (25 g) was successively extracted with various solvents in a Soxhlet's apparatus when the following amounts of extract dried at rev' were obtained.
