BUREAU OF CHEMISTRY. 591 



The administrative work and correspondonce, especially that re- 

 lating to the onl'orcenient of the food and drugs act in so far as it 

 applies to waters, cattle foods, and remedies and grains, and the 

 preparation of cases involving the above-mentioned products, have 

 required a large amount of attention from the chief of the division, 

 who is also a member of the Insecticide and Fungicide Board, which 

 has charge of the enforcement of the insecticide act of 1910. AVork 

 in connection with this board has occupied about one-third of the 

 time of the chief throughout the year. Some time has been given to 

 travel in connection with inspections of water plants and attending 

 meetings of societies which have for their aim the advancement of 

 science in so far as it applies to the substances considered in this 

 division. 



The miscellaneous division during the past year examined approx- 

 imately 2,105 routine samples, besides a large number in connection 

 with special investigations. Many of the samples required 20 to 30 

 individual doterminaticms, and few of them required less than 8, so 

 that probably about 25,000 individual determinations were made. In 

 the following table appears a statement which shows in a concise 

 form the number of samples of various materials examined :
