branes will be usually found to have suffered more or less ffoih 

 the attack. Sometimes the general vascularity is only slightly 

 increased, but in most cases the vessels of the pia mater will be 

 found distended with blood, and that usually in the degree of ex- 

 citement exhibited, but in no instance have I observed the mem- 

 branes thickened, as in idiopathic phrenitis. The inflammatory 

 appearances within the cerebral cavity are usually less considera- 

 ble in those cases called dumb madness than in the raging. As 

 might be expected, the spinal brain, or spinal marrow, as it is called, 

 usually participates with the cerebral aff'ection : sometimes the 

 morbid marks are greater here than in the brain itself. The 

 membranes of it are often highly injected^^, the canal likewise is 

 sufi*used with fluid, and the nervous column itself presents diseased 

 appearances. — Journal Universel des Sciences Medicales, tom.

Much of the general tumefaction which existed during life 

 about the back of the mouth, disappears on the collapse of death, 

 but it commonly leaves the base of the tongue and the sublingual 

 glands enlarged and injected as well. Mr. Youatt has often, he 

 observes, found the parotid and submaxillary glands gorged also. 

 As regards the tongue, not only its base generally remains tume- 

 fied, but its papillae are particularly enlarged, as also the mucous 

 glands of the under surfaces, which have been the subject of 

 critical examination of late years ; and which Mr. Youatt, with 

 much probability, thinks have been mistaken by Marochetti and 

 others for his famed pustules. It is also important to be aware 

 that, whether a dog has been wormed or not wormed, no differ- 

 ence whatever is found in the appearance of the under surface of
