NASINI (Ber., 21, 2153-2155 j.-The authors have made determinations of the molecular weight of sulphur, phosphorus, bromine, and iodine, by Raoult's method in a similar manner to that described (Ber., 19, 2527). Benzene was the solvent employed in the case of sulphur, and solutions of various concentration were experimented on. The
more » ... cient of depression was constant, and the molecular formula was found to be S,. Aq-ueous and acetic acid solutions were employed for the determinations with bromine, and the results show that the molecular formula is Br,. The molecular foi*mula of iodine was found to be I" when very dilute solutions of benzene are employed, but in more concentrated solutions the results seem to indicate a greater complexity of the molecule. The molecnlar depression is constant in acetic acid solutions, and the results obtained point to molecular formula intermediate bettween I and I,. From the results obtained with phosphorus in benzene solution, it seems probable that, i t coutains a mixture of molecules of P, and P" but the sample employed was not quite pure. F. S. K.
