 in many cases, without one manifestation of any dis- 

 position to bite, or do the smallest harm. I have seen 

 this particularly in pugs and terriers. A very great 

 number, indeed a majority, of those who arc affected 

 have obstinate costiveness, and which is a very gene- 

 ral and well marked symptom. This costiveness is 

 found to be very obstinate, and, when overcome, it 

 yet does not appear to produce any relief. It ap- 

 pears to arise from the peculiar inflammation that 

 exists in the bowels of most of tliem, and it is to this 

 source that it is so common for them to appear para- 

 Ivsed and weak in the loins. I have seen an aifcc- 

 tion of the bowels produce a tendency in a dog to 

 sit constantly oh his rump wholly upright, and in 

 others it has produced convulsive spasms not unlike 

 St. Vitus's tlance, and I have seen one side wholly 

 paralysed, while the other has been unaffected : but 

 an evident failing in the loins is a very connnon ac- 

 companiment to the disease. There is also in every 

 one of them marks of great oppression on the head ; 

 for in the most furious, however watchfid they may 

 appear, they are every now and theu closing their 

 eyes, and the head drops as in dozing. The dura- 

 tion of the complaint is various in dogs: few die 

 sooner than tlie third day, and few survive longer 

 than the seventh. The average number die on the 

 fourth and fifth day. In other animals the existence 

 of the complaint is much about the same time. 



I shall now proceed to notice the appearances on 

 dissection, as strict attention to this subject will often 

 be found to be of the utmost importance ; for very 

 frequently it is only after death that an animal is sus- 

 pected of being affected with madness, though he
