LETTER OF TRANSMITTAL. 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF ANIMAL INDUSTRY, 



Washington, D. C., July 2, 1912. 



SIR: I have the honor to transmit herewith a manuscript entitled 

 "The Roundworms of Domestic Swine, with Special Reference to 

 Two Species Parasitic hi the Stomach," by Mr. W. D. Foster, of the 

 Zoological Division of this bureau. I respectfully recommend its 

 publication in the bulletin series of the bureau. 



The paper deals particularly with two species of nematodes which 

 have recently attracted considerable attention in connection with 

 the Federal meat inspection. The parasites are shown to be of wide 

 distribution and frequency of occurrence hi American swine, and they 

 are a source of possible serious injury to these animals. 



The illustrations were drawn by Mr. W. S. D. Haines, of this 

 bureau. 



Respectfully, 



A. D. MELVIN, 



Chief of Bureau. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
