Report of work carried out by the Biological Department of the Bureau 



during the financial years July 1914 — July 1916. 



On account of the war, the working out of the Bulletin Statistique has 

 been a great deal delayed by shortage of material. Nevertheless, the de- 

 partment has succeeded in finishing the statistics for the years 1911 and 1912, 

 and it is expected that these two years will be edited during the beginning of 

 1917. Further, the work with the statistics for the year 1913 has been started, 

 and if the material still wanted should arrive, it is expected to be finished during 

 the spring of 1917. 



At the beginning of the war Dr. Reichard left the Department.
