EXPERIMENT STATION REPORTS. 139 



very lame in left liiud leg in a. m., but seemed all right in p. m. ; no 

 appetite; sore mouth; muzzle dry and cracked with lateral fissures ; slight 

 lachrymation ; had been slight, mucopurulent nasal discharge; tempera- 

 ture had been reduced from 106° and 107° to normal. This was the 

 only case that showed signs of recovery. 



Another of the three cases was a heifer calf less than a year old; 

 sick about five or six days; slight muco-purulent nasal discharge, slight 

 lachrymation and an opacity of the cornea of right eye with consider- 

 able precipitate in anterior chamber of eye; ate only very little; ap- 

 peared dull ; showed no pain ; passed normal, firm feces during day and 

 urinated normally; temperature, 100.8°. 



The last of the three was a black yearling steer; sick about five days; 

 three to five degrees of fever throughout ; passed about a pint of liquid 

 manure the day before, probably all that the bowels contained; no 

 apj)etite ; lachrymation abundant, purulent discharge from inner can- 

 thus of each eye; slight mucopurulent nasal discharge; very weak and 

 hollow in flanks; made to stand with difficulty; temperature, 105.8°. 

 Killed in p. m. Just before killing, blood was drawn from the right 

 jugular vein with sterile canula into sterile bottle. A sluggish stream 

 at first, quickly subsided into drops and the canula became filled with 

 a clot before an ounce had been drawn; killed by blow over brain and 

 cut throat. 



Post mortem: Blood flowed readily from carotids and jugulars at 

 first, but soon ceased. On removing the hide, immediately, the sub- 

 cutaneous tissues below the carpal and tarsal joints was cold, there 

 was some yellowish oedema in subcutem of brisket; all the subcutane- 

 ous vessels contained some blood and all the capillaries throughout 

 the body on the membranes seemed to contain enough blood to make 

 them visible; there were very numerous j^etechiae and ecchymoses in 

 connective tissues upon cutting through pectoral muscles. The peri- 

 cardial sac showed a few petechiae near its attachment to diaphram ; 

 the right ventricle Avas distended with a dark clot; lungs were pale ex- 

 cept the dorsal portion which was considerably congested; all lymphatic 

 glands were slightly odematous; the liA^er was very pale, almost par- 

 boiled in appearance, except for a few congested patches; the gall 

 bladder was distended with about a ])int of normal colored bile; the 

 kidneys were normal; spleen, possibly slightly enlarged but normal 

 color and firmness; bladder, partly full, urine normal; brain normal in 

 color meninges pigmented black; possibly, brain substances, slightly 

 softer than normal; nasal mucosa, only slightly congested; rumen, 

 fairly Avell distended and contents normal; nuicosa, normal; reticulum, 

 normal ; omasum, full and contents partly dry, mucosa, normal ; aboma- 

 sum nearly empty, mucosa, normal ; the entire intestinal mucosa Avas 

 congested more or less, in places the congestion expending through into 

 submucosa and vessels of serosa injected; Peyer's patches congested 

 especially; about three feet from the theovocal valve, the mucosa of 

 ileum showed about one foot of considerable hemorrhage; the intestinal 

 contents consisted of only a slight amount of nearly digested food ad 

 lieriiig mucosa; the periostum of the bones Avas considerably congested 

 and the marrow adjacent to the inner surface of the shaft of the bones 

 Avas tinged Avith blood.
