DISEASES OF THE NERVOUS SYSTEM. 247 



brought for observation on treatment, to the Vienna Imperial 

 Veterinary Institute, and published in the " CEsterreichische 

 Vierteljahresschrift fiir Wissenschaftliche Veterinarkunde," 

 for 1875* we observe tliat in the session of 1873-4, there were 

 no fewer than 125 dogs admitted as rabid, or suspected of 

 being affected with rabies. Though some of the pathological 

 alterations were so frequent that they could be accurately 

 grouped, yet others were so inconstant that there could not 

 be said to be any certain indication of the presence of the 

 disease. Iij some were found alterations in the brain ; in 

 others, changes in the blood, lymphatic glands, and kidneys ; 

 and in others, morbid manifestations in the digestive organs 

 were met with. The malady prevailed as an epizooty, and an- 

 imals of both sexes, various a,ges and breeds,. when or whether 

 bitten often unknown, were at different times brought to the 

 Institute. Frequently little could be learne4 with regard to 

 the animals which were brought dea.d, and even their con- 

 dition previous to death could rarely be ascertained. With 

 regard to the value of some pathological alterations in forming 

 a judgment as to the presence of the disease, the following 

 epitome is given of the result of the necroscopical examina- 

 tions made of these animals : 



a. Alterations in the brain. 1. Haemorrhage into the 

 subcutaneous tissue of the cranium of a suspected dog. 2. 

 Haemorrhage into the dura mater of two rabid and one sus- 

 pected animals. 3. Injection in the pia mater and plexus, 

 choroides. in 28 rabid and 2 suspected. 4. Hyperaemia of the 

 brain in 2 rabid. 5. Softening of the brain in various degrees 

 — from mere shining softness {gtrzdnd und weierseiti) , to com- 

 plete pulpy liquefaction — in 35 rabid and 2 suspected 

 animals (of these the' whole brain was generally involved in 

 3 rabid cases ; the cerebellum in 3 rabid, and 2 suspected ; 

 the upper surface and base of the brain in i rabid animal. 6. 

 Distension of the lateral ventricles, through a collection of
