 family as well as the equine species, they being the subjects of 

 constitutional defect in the form of scrofula. Derangement of the 

 digestive organs almost always affect the brain, in consequence of 

 sympathetic relations existing between the two. Hence, in view of 

 preventing disease of the biain, we must keep the stomach in good

 do not differ materially from those which are present in dropsy of 

 the brain. In the early stage, the animal appears lethargic, sleepy, 

 and, when urged to move, reels and comes near falling. The head 

 is usually somewhat depressed, yet it is often inclined to one side:

 hips and shoulders, until, as a matter of charity, the owner pufc»
