ises, Ave cordially invite such to co-operate with ns in our endeavors. 

 With the aid of those associated with us in Government work, partic- 

 ularly of Messrs. L. O. Howard, E. A. Schwarz, and John B. Smith, we 

 feel justified in expressing this hope and send to all, who may receive it, 

 this first number, greeting. 



During a large part of the year the force of the Division is actively 

 engaged in experimental work and original research, which fact will pre- 

 clude the issuing of this bulletin as regularly as an ordinary monthly; 

 but it will be our endeavor to issue it on an average once a month, and 

 to complete a volume with each year.
