THE LUNG PLAGUE.

I could not detect friction sounds, loud respiratory murmurs, especially at the lower part 

 of the trachea and involving one lung. It is not a little remarkable to notice the want of 

 faith of some persons who watch the separation of such cattle, with great doubt as to the 

 correctness of the observation. In rinderpest the elevation of temperature occurs before 

 all other signs, and to a less marked extent this is the same with splenic fever ; but in 

 pleuropneumonia there is reason to believe that acute observation would reveal first the 

 local change and then the fever. 



In order to show the value of the thermometer in this disease, I subjoin the observa 

 tions made by me on two herds of cows suffering from it, and which I inoculated on the 

 26th of February, 1869, at Alexandria : 



Mlt. BIEMULLERS COWS.

Of Reid s cows, JSTos. 11 and 14 were sick, and of Biemiiller s, Nos. 9, 14, 15, and 

 19. Some doubt exists as to No. 19; I had not opportunity of seeing her again. Mr. 

 Reid thinks she might have been at heat, but from the indications, however slight, asso 

 ciated with the elevation of temperature, I believe it was one of the numerous latent cases 

 which the thermometer alone reveals to us. Nos. 14 and 15 were in the earliest stages of the 

 malady, and both grew worse, suffered for three weeks, and then recovered. 



OBVIOUS PREMONITORY SIGNS. 



The obvious premonitory signs are shivering fits, as in ordinary fever, but their tran 

 sient and mild character lead to their often being passed unnoticed. The animal s coat 

 looks dull, staring, and the skin is often rigid. An occasional cough of a dry and harsh 

 character is noticed, and, when inspecting a herd in a field, if the cattle are made to move 

 briskly, several will be found to cough. For some days the cattle appear to thrive well, 

 and milch cows yield a copious amount of milk. It has been remarked that they appear 

 full indeed fuller in the early morning than other animals which, like them, had not fed 

 since the previous evening. The excrement is dry, and urine somewhat scanty. 



An expert dairymaid, in the habit of milking cows where the disease prevails, is apt
