io8° or 109°. The more acute the case and the hotter the 

 weather the greater the rise. The highest records are obtained 

 late in the day, the lowest in the morning. The temperature 

 often rises for two to four days, and then suddenly drops with the 

 occurrence of collapse and imminent death. While the thermo- 

 meter is of the highe,st value in taking the temperature, yet the 

 extraordinary hyperthermia is easily detected by grasping the root 

 of the horn or ear, or by feeling the nose, feet, anus or lips of the 

 vulva. 



After 2 or 3 days the respirations become accelerated to 60 to 

 100 per minute, and the pulse to 90 to 100 or more. There is com- 

 plete loss of appetite and rumination after the development of 

 these symptoms, the mouth is hot and it ma}' be dry, the muzzle 

 dry, the head pendent, the eyes dull or semiclosed and congested 

 (usually icteric), the bowels confined, to be relaxed again as the 

 fever subsides. A disposition to stand or lie down in water has 

 been frequently noted. Nervous .symptoms are usually present. 

 The extreme dulness, languor, and apathy, the drooping head 

 and ears, the unsteadiness of the support the animal staggering 

 or propping himself up by spreading all four limbs, and the 

 tendency to assume and retain a recumbent po,sition, are marked 

 phenomena in our domesticated northern cattle. The paresis 

 may absolutely incapacitate the animal from getting up. In our 

 wilder range cattle it may show itself in active delirium and 

 lyignieres notes the same of the Pampas cattle in Argentina. The 

 animal lying dull and apathetic (triste), on being approached 

 may rai-se his head, open his eyes and glare threateningly at the in- 

 truder. Sometimes when trembling violently, and swaying ready 

 to fall, he will marshal all his remaining energy to plunge at a 

 man on foot or mounted. Some have become blind and uncon- 

 sciously walked against obstacles, others have been noticed to run 

 in wide circles. 



The milk .secretion is suppressed, any little that can be drawn 

 in the advanced stages having a thick, creamy appearance. 

 Abortion is common in the pregnant cow. 



The condition of the urine has, however, always drawn 

 especial attention and the names red-water and hcemoglobinuria 

 have accordingly been largely applied to the disease. When, in 

 infected areas, the milder types of the disease have failed to show 

 red-water (Jamaica), the identity of the affection with Texas
