 found by Rudolphi in the" duodenum of a calf, but for long was 

 considered of no consequence as a pathogenic factor. Recent 

 observations of Stiles especially have shown, as might have been 

 expected of such a parasite, that all that was wanted was the 

 opportunity for encrease and diffusion to make it a virtual scourge. 

 In examining the unthrifty cattle of DeWitt, Gonzales, Victoria 

 and Calhoun Counties, Texas, he found the worm in the upper 

 part of the duodenum of half the animals subjected to necropsy. 

 The habit of the genus of sinking the teeth into the mucosa and 

 sucking strongly by the aid of the muscular oesophagus, and the 

 oozing of blood through the many orifices that have been sucked 

 and abandoned, deplete the vascular system, the recuperation of 

 which is interfered with by the local irritation and the disturbance
