Sera and vaccines. — There has been little change in the produc- 

 tion of these biological products. In 1911 there were three 

 technical employees engaged in the preparation of sera and vac- 

 cines, whereas at the present time only the head employee of 

 these remains. Some of the work accomplished in the past five 

 years is shown by the following table:

» The Pasteur treatment for rabies is now practically entirely administered by the Bureau 

 of Science, although we continue to send out rabies vaccine when it is requested. Thirty-four 

 patients were treated at the Bureau of Science in 1912, 36 in 1913, 35 in 1914, and 112 from 

 January 1 to December 31, 1915. 



This table shows that as much work is accomplished now as 

 formerly, and in some cases there is an increased demand for 

 sera and vaccines. In order to accomplish so much, the employee 

 has been compelled daily to work many hours overtime as well 

 as on holidays and Sundays. Great difficulty was experienced 

 in securing suitable horses for the production of diphtheria anti-
