    appearance and physical properties of the compound under discussion with those of g’lucosazone are such that the two must be regarded as belonging- to the same class of chemical compounds. So far, therefore, Dr. Pavy’s conclusions are completely confirmed. The somewhat higher melting-point, optical inac- tivity, and slightly different crystalline appearance of the new osazone as compared with glucosazone are sufficient to show that it is not identical with the latter. It exhibits to a marked degree the tendency of forming supersaturated solutions, in which respect it again differs from glucosazone. As far, however, as my own personal experience goes, the osazone derived from galactose also possesses the character of forming supersaturated solutions. In conclusion, I wish to state that with Dr. Pavy’s concurrence I intend to continue the study from a chemical point of view of the apparent carbohydrate compounds produced by the hydrolysis of proteid. I venture to hope, therefore, that I shall be in a position at no distant date to give a detailed ac- count of further experiments on this most interesting problem. It is my pleasure to express my thanks to my colleague, Mr. Julian L. Baker, for the assistance he has rendered me during the prosecution of these ex- periments. Next, Dr. Paton tries to deprive my views of the support which Hammarsten’s and Kossel’s researches
