priest or the midwife may say to the contrary. By abstrac- 

 tion of so much blood as brings down the pulse we lessen 

 for some time — 



The fullness of the vessels, 

 The number of red corpuscles, 

 The force of the heart's impulse, 

 " arterial impulse, 



The excitement of the nerve centres. 

 Equalize the circulation. 



And by each and all of these influences we diminish the 

 vascular excitement connected with the inflammation, and 

 thus lessen the amount of resultant exudation, and make its 

 changes less destructive. 



Other practitioners of the new school try to produce the 

 same effects by powerful sedatives, and with success in many 

 cases. For this purpose 60 to 80 drops of aconite, in water, 

 or sulphuric ether, every two hours, until there is depression 

 of the circulation indicated by the pulse ; at the same time 

 giving one ounce of nitre in a pint of water. 



The symptoms that do not warrant either of these depres- 

 sive measures are — 



When the patient is shivering and the 

 skin cold. 

 ^ r When the symptoms of disease continue 



btage ot , ^^^ several days. 

 Transudation ^^.^^^^ ^^^^ ^^^^^ ^^ ^^^^^^^ ^^^ f^^^l^_ 



When signs of debility are observable. 

 ^When exudation has taken place. 



These are contra indications that no depletive measures 

 can be pursued with safety, and they are such as most people 

 of ordinary intelligence can know for themselves, and of 

 course avoid. 



The diagnosis, symptoms, and treatment of pneumonia in 

 its first stage we have tried to show as briefly and clearly as 

 the plan of this little work would permit. We have not said 

 all, but enough for correct and safe management of animals 

 in this disease.
