EXPERIMENT STATION RECORD. 



i. <?., respiration experiments, form a group by themselves and are not 

 subdivided. The experiments in which the nitrogen balance was 

 determined with cattle, dogs, doves and poultry, goats, horses, rabbits, 

 sheep, and swine constitute separate groups. The experiments with 

 animals in which the income and outgo of carbon was determined form 

 a group by themselves, as do also the experiments with animals in 

 which the income and outgo of energy was determined. 



The purpose of the compilation is primarily to give a brief epitome, 

 so far as practicable, of the objects and results of individual tests. The 

 tables furnish the framework of such epitome, while supplementary 

 matter is given in the accompanying text. 



The bulletin includes an introductory chapter giving historical infor- 

 mation concerning the subject, explaining the scope and plan of the 

 compilation, and calling attention to some of the points to be consid- 

 ered in drawing deductions from the experiments. A name and subject 

 index is appended. 



Dietary studies in New York City, W. O. Atwater and C. D. 

 Woods ( U. S. Dept. Agr., Office of Experiment Stations, Bui. 46, pp. 

 117). — Twenty-two dietary studies of families living in a congested por- 

 tion of New York City are reported, together with studies at a mission 

 and a day nursery in the same region. The methods followed in mak 

 ing the investigation were practically the same as those described in 

 Bulletin 21 of this Office. The families were selected as typical of the 

 so called poor classes usually encountered by philanthropists and 

 mission workers in the congested districts of large cities. 



Tables are given showing the kind and amount of food purchased, 

 wasted, and eaten, and its cost, composition, and fuel value. The more 

 technical details of the studies are included in an appendix. The 

 results of the studies are briefly summarized as follows:
