352 THE MANAGEMENT AND DISEASES OF THE DOG. 



dogs made in Rudneff's pathological laboratory at St. Peters- 

 burg. The parts examined were the eerebral hemispheres, the 

 corpora striata, thalami optici, cornua ammonis, cerebellum, 

 medulla oblongata, medulla spinalis, and the sympathetic 

 and spinal ganglia. The changes were always most marked 

 in the ganglia, and were as follows : i. The vessels were 

 much distended and filled with red corpuscles. Here and 

 there along their course were seen groups of red corpuscles, 

 and round indifferent elements (probably emigrated white 

 corpuscles) scattered in the perivascular spaces. The walls 

 of the vessels were spotted with hyaloid masses of various 

 forms, sometimes extending into and obstructing the lumen 

 of the vessel-like thrombi. Not far from these were collec- 

 tions of white and red corpuscles. 2. There was found to be 

 a collection of round, indifferent elements in general around 

 the nerve-cells, sometimes penetrating into the protoplasm of 

 the cells to the number of five or eight ; sometimes in such 

 number as quite to displace the cell-protoplasm. The number 

 of migrated cells produced various changes in the form of the 

 nerve-elements. The nuclei of the cells were sometimes 

 pushed forwards towards the periphery by the intrusive ele- 

 ments. In other cases the nerve-cells seemed entirely re- 

 placed by masses of round indifferent corpuscles. These 

 changes were seen even in isolated nerve-cells. The author 

 points out the analogy of these changes to those described by 

 Popoff in enteric fever and injuries. 



With regard to the innocuousness of the milk derived from 

 rabid animals, there is a conflict of opinion. Gases, however, 

 are on record both of human beings and the offspring of 

 animals becoming affected through partaking of milk secreted 

 by hydrophobic and rabid subjects ; but many of these cases, 

 it must be confessed, are involved in doubt. 



Mr. Fleming, in his work on " Rabies and Hydrophobia," 

 observes : " the influence of the milk obtained from animals 

 supposed to be infected with rabies has received much atten- 

 tion, and, as in the case of the flesh, the facts relating to'its
