Fresh and refrigerated meats, A. Gautier (Rev. Hyg., 19 (1897), 

 pp. 289-303; 394-115). — On the basis of statistics of the amount of food 

 brought into Paris between the years 18S0 and 1890 the daily amount 

 consumed per man is calculated. A study is reported of fresh and 

 refrigerated or frozen beef and mutton. The preserved mutton and beef 

 came from the Argentine liepublic, and had been frozen from five to 

 six months. The samples analyzed were freed as far as possible from 

 tendon and visible fat. The results follow :
