round and round, rushing first to one side, and then to the other, 

 biting at the manger and hay-rick, snapping at the bars of the latter, 

 and even worrying at their own limbs, attempting to climb up the 

 sides of the box with their fore feet, falling over backwards, and when 

 lying on their side, the limbs moved as if in full trot, the breathing 

 was loud and quick, perspiration rolled off their bodies, eyes were 

 staring, rolling, and bloodshot, mouth open and frothy, and at intervals 

 they gave out peculiar screams or cries ; when on their feet, they were 

 dangerous to approach. Treatment : While down, the animals were 

 secured, and well bled from the temporal artery ; chloral-hydrate and 

 bromide of potassium were also administered, and cold water applied 

 to the head, but all to no purpose, as both animals had to be 

 destroyed. 



565. Organic Changes, such as abscesses in the horse's brain, 

 may arise from complicated or " bastard " strangles. This pyaemia 

 form of strangles, unfortunately, in some seasons is not uncommon. 

 Like the commencement of all brain affections, when the abscesses 

 are developing in that organ, there is great drowsiness and dullness, 

 the horse hangs its head in a sleepy condition, with pulse full and 

 slow, and breathing quiet and deep; and any food that is taken is 

 eaten in a sort of mechanical manner. As the case progresses, the 

 animal commences to wander round the box, presses its head in the 

 manger, or against the wall, the breathing and pulse becomes quicker, 

 and finally, the animal hangs its head on one side, and day after day, 

 walks, so to speak, round and round its own head, making it a centre. 

 These cases always end fatally. On post-mortem, the brain is found to 

 be a mass of pus, or matter ; thus showing, in cases of simple 

 strangles, how necessary it is that every care and attention should be 

 paid at the commencement, and remedial measures be adopted so as 

 to prevent these fatal terminations. 



566. Hydrocephalus, or water on the brain, I have met with 

 in young foals, their foreheads being, as a result, much enlarged and 

 distended. The little animals were very dull and sleepy, yet they took 

 milk freely. As they grew bigger and stronger, the water became
