January 13, 1919 A STUDY OF SOME OF THE CHEMICAL CHANGES WHICH OCCUR IN OYSTERS DURING THEIR PREPARATION FOR THE MARKET. By Edward E. Smith, Junior CONTENTS. Scope of investigation 1 Commercial treatment of oysters 2 Experimental work 3 Methods of analysis 3 Series 1 4 Series II 6 Experimental work (continued): Series III 8 Series IV 9 Series V 13 Summary 23 SCOPE OF INVESTIGATION. This bulletin gives the results of an investigation to determine the amounts of ammoniacal nitrogen, amino-acid nitrogen, moisture, total solids, ash, and sodium chlorid present in oysters under the various conditions through which they pass in ordinary commercial practice in the oysterhouse, and to ascertain the effect of washing and soaking on both the chemical composition and physical condition of the oysters. The investigation was conducted during the fall and winter of 1914-15, in certain oysterhouses in Connecticut, selected as being representative of the oyster industry throughout the North Atlantic States. The oysters used were grown in various beds, rang- ing from New Haven, Conn., on the east, to Raritan Bay, N. J., on the west. As work was done in several houses, each using a different method of treatment of the stock, the methods given represent commercial practice at that time and in that locality, but may not be representative of later practice or other localities. The experi- ments which were made to show the results of various special treat- ments do not represent commercial practice. i The writer wishes to express his indebtedness to Dr. E. D. Clark and Mr. L. H. Almy, who instructed him in the methods of determination of ammoniacal nitrogen and amino-acid nitrogen; to Mr. Carleton Bates and Dr. Lester Round, who assisted materially in planning the work and under whose direction it was ca
