ness. The conjunctiva is reddened, and the heart beat 

 rapid. The respirations are slow and regular or they may 

 be stuporous and irregular, of the Cheyne-Stokes' variety. 

 The temperature is about normal. 



If the animal does not die at once, it is usually left with 

 a partial or complete paralysis, monoplegic or hemiplegic in 

 character, depending upon the size and location of the 

 hemorrhage. If the hemorrhage is small and away from 

 the cortex, there will be only slight convulsions shown 

 followed by muscular incoordination, the animal stumbling 

 or staggering from side to side and falling. 



Diagnosis. The sudden occurrence, the history, the char- 

 acter of the respiration and the paralysis make the diagnosis 

 not difficult. 



Prognosis. The prognosis should be unfavorable, only the 

 milder cases terminating favorably. 



Treatment. Place the animal in moderately cool, well- 

 ventilated quarters away from exciting influences. Cold 

 applications should be applied early to the head, and if there 

 be convulsions, antispasmodics (morphin, 0.0162-0.1944) may 

 be administered. Give potassium iodid (0.1-0.8) to resorb 

 the hemorrhagic exudate, and keep the bowels open with 

 mild purgatives, such as castor oil (15.0-40.0). Later the 

 paralysis may be treated by the administration of strychnin 

 to almost the toxic point (0.00054-0.00216). The faradic 

 battery is also useful in treating the paralysis. 



As this condition is brought about by a high blood pres- 

 sure and is most commonly seen in plethoric animals, it is 

 well to reduce the blood pressure by depletion methods, such 

 as a restricted diet and occasional bleeding from the saphena 

 vein, to prevent another attack. 



TUMORS OF THE BRAIN. 



Tumors of the brain are rare in small animals but are 

 occasionally observed. They may involve any part of the 

 brain and its covering membrane, and histologically may be 

 of any type.
