In the introduction Dr. Salmon states that great care has been be-

 drawn from nature. 



The uodular disease of the intestines {(Esophagostoma columbianum, Curtice), to-

 common and wide-spread, bnt its cause and nature were mysterious until they were 

 discovered through the investigations of this Bureau. * * * The facts obtained 

 in the investigations of the fringed tape-woriu and the hair lung-worm are also of 

 more than ordinary interest.
