A sub-normal temperature may be produced artificially at a 

 much lower point than it can occur in disease. The best records 

 of this are in the human. Practitioner Peters took the tem- 

 perature of a woman found drunk in the winter and it was 78.8; 

 she recovered. This is the lowest case on record. It is said 

 that an animal cooled to 75.2 will die. 



^ The following is a table of the temperature of the domestic 

 animals, taken from the German with the addition of Dr. 

 Baker's : 



Animal. No. of Observ. German. Baker. 



Horse 7S 99.9 100 



Ox 16 103.4 101-2 



SHeep 39 103.1 102-3 



Dog 162 102.6 101-5 



Hog 13 103.4 102 (Brog.) 



Fowls .. 106.7-111 107-111 



The temperature varies somewhat according to the atmos- 

 pheric conditions and depends upon the amount of exercise to 

 which the animal has been subjected. In taking the temperature 

 the animal must be quiet, exercise raises the temperature. Driv- 

 ing animals raises their temperature, especially hogs, whose fat 

 prevents them from cooling off. 



In conducting the mallein test for glanders in horses, the 

 temperature should be taken before feeding and drinking; cold 

 water lowers the temperature. The animals should be com- 

 fortably placed so as not to cause them any excitement. 



CONGESTION. 



Congestion (Latin conger e, to heap up) is defined as the 

 increased flow of blood to a part. It is also called hyperaemia, 

 meaning an excess of blood. It is divided into Active and Pass- 

 ive. The active is confined to the arterial system, the passive 

 to the venous. There is also another congestion which is called 

 HYPOSTATIC. Congestion is described with the name of the 

 organ affected; as, cerebral, hepatic, renal etc. 



A physiological congestion may be produced by nature to 

 allow the organ to perform its function. For example, as par-
