Infested calves shake the head vigorously, become emaciated, often 

 race about madly until completely exhausted. The ears become in- 

 flamed and the secretion of wax is greatly stimulated. Deafness is 

 said often to result in infested horses and mules. 



The following account is by a man whose ear was inhabited by a tick 

 of this species. This account is worthy of note because the course of 

 events is here rather accurately given, together with the sensations 

 aroused and other matters of interest. Mr. L., writing from Lancaster 

 (California), states: " I left Berkeley with a horse and wagon on the 3d 

 of September (1915) and drove about four hundred miles to Lancaster, 

 Los Angeles County. I slept on the ground every night except one, 

 arriving here on September 15. Some of my camping places were in, 

 others along-side of, cattle ranges or pastures. One of the places I dis- 

 covered before morning to be a regular camp for twenty or thirty 

 cattle of all sizes. This is where I did not sleep on the ground. 

 The cattle came in after I had made camp about dark and it was too 

 late for me to find another place, so I moved my bed into a small 

 shack, near the barn with old straw on the floor, which was about a 

 foot above the ground. Still I was right among the cattle. This 

 was the night of September 5, at Corrall Hollow, east of Liver- 

 more. The last night out, September 15, I slept on land that is 

 used only for grazing and have been working on similar ground ever 

 since; however, there are only a few cattle on the range. My other 

 sleeping places were mostly along the roadside, and sometimes cattle 

 were around. At other places there were none and I think there have 

 been no cattle near the house I live in for several years, or perhaps 

 a few passing near it once in a while. " Our records show that Mr. L. 

 went through territory where the spinose ear tick occurs. In 

 his first letter, dated December 10, 1915, he says "I am sending 

 you ... a bug . . . which came out of my ear, and which 

 was living there probably six or seven weeks. . . . About six or 

 eight weeks ago I began hearing unusual noises in my left ear. 

 Sometimes hours would pass without hearing them; sometimes every 

 few minutes, either day or night. The noise would saw awhile without 

 any regularity as to time or duration. I could feel no movement in my 

 ear like anything alive. Finally I thought I had better have it ex- 

 amined, so went to a local physician and told him I thought something 

 was in my ear. He examined it and said 'Yes, there is something in 

 there. I'll see what it is and what I can do for it.' After prodding 

 around awhile he asked, 'What do you suppose that thing is in there?' 

 I replied that I cHd not know. 'Well, it is a live bug, but I killed it.' 

 He pulled out what looked like a clot of good red blood, about the size 

 of a small pea, mixed with small bits of soft membrane. Then he
