Effects of enforcement of the National Food and Drug Law of June 

 30, 1906, J. FousT (Amer. Food Jour., 15 (1920), No. 6, p. 26). — This is a brief

Drugs and foods, C. D. Woods (Maine Sta. Off. Insp. 95 (1920), pp. 28).— 

 This publication consists of the reports of analyses of samples of drugs and 

 foods sent to the station for examination during 1919. 



For the purpose of comparison of clams on sale with specimens bandied under 

 known conditions and from salt and brackish water, specimens were collected 

 and examined for percentage of liquids and solids under varying conditions. 

 Tables are given showing the composition of clams opened raw, compared 

 with clams from the same source but dipped for two minutes in boiling salt 

 water or in boiling fresh water before opening, a'so of clams dried without 

 washing in fresh water as compared with samples washed in fresh water after 

 shucking. 



From these analyses the conclusion was drawn that good, fresh-opened, well- 

 drained clams should carry not more than 10 per cent of liquids and not less 

 than 17 per cent of solids. Judged by these standards, the practice of water- 

 ing clams by placing them in brackish water is apparently quite common.
