or frequent vomitings. Sooner or later, diarrhoea comes on. 

 The evacuations are bilious, dark, and offensive ; the counte- 

 nance is expressive of anxiety and uneasiness, and there are 

 evident indications of prostration. Four or five days from the 

 onset, after shivering, vesicles appear on the head, and thence 

 gradually spread to other parts of the body : these vesicles 

 subsequently break, and the resulting scab falls off in due 

 course. 



"A pack of hounds ate tbe carcases of some sheep, dead 

 of clavelee (small-pox). Seventeen of them became ill. .At 

 first distemper was suspected, as the dogs were low-spirited, 

 weak, paralytic in their limbs, and had a viscid, greenish 

 discharge from their nostrils. A copious crop of ' pustules ' 

 appeared, and the disease was thereafter, rightly or wrongly, 

 regarded as small-pox. Eleven died. 



" It has been stated that some dogs were infected from 

 sheep with this disease, during the recent Wiltshire epidemic ; 

 and that in both animals the disease was identical in its 

 symptoms. 



"In small-pox the skin is affected in the following man-

 and dotted with small roundish spots, either isolated or irregu- 

 larly clustered together. Each spot gradually gets larger, 

 and its centre becoraes prominent and pointed, and contains 

 a clear fluid, which subsequently acquires a pus-like appear- 

 ance. Each spot is now flattened ; the contained fluid 

 escapes on the rupture of its envelope ; scabs form from the 

 drying of the fluid, and gradually fall off. In some parts of 

 the body a permanent minute scar remains, and the hair is 

 destroyed for good." 



Mr. Fleming observes :* " This is a rare malady, and may 

 be developed directly or by contagion ; it is supposed to be 

 also produced by the variola of man and of the sheep. It 

 chiefly affects young dogs, although old animals are not
