Mr. Alex Wetmore , 
Corinne, Utah. 
Dear Mr. Wetmore: 
Both lots of samples of water which you sent in were 
safely received am have been forwarded to the Bureau of 
Chemistry. We referred the bird parasites in conformance 
with the suggestion made in a previous letter, and they 
came back with the statement that they could not be identified 
without a complete review of bird parasites in general, which 
at the present time is impossible. 
I do not understand from your letter whether you wish 
to have chemical or microscopical examinations of blood and 
renal matter made. The purpose would undoubtedly make a 
difference in the method of preservation desirable and 
certainly would decide to whom I shall g o to get instructions 
*> 
regarding a method. 
The formalin and other supplies which you request have 
been sent. I would suggest that, if you find it practicable, 
you buy formalin local ly since we have no convenient way of 
sending it in large quantities. 
With best wishes, 
Sincerely yours, 
LaJ. I c ( c CHaxjl
