82 DISEASES OF THE GREYHOUND. 



The near approach of this eruption is announced by an increase of 

 fever. 



' On the second day the spots are larger, and the integument is 

 slightly tumefied at the centre of each. On the third day the 

 spots are generally enlarged, and the skin is still more prominent 

 at the centre. On the fourth day the summit of the tumour is 

 yet more prominent. Towards the end of that day the redness of 

 the centre begins to assume a somewhat grey colour. On the 

 following days the pustules take on their peculiar characteristic 

 appearance, and cannot be confounded with any other eruption. 

 On the summit is a white circular point, corresponding with a 

 certain quantity of nearly transparent fluid which it contains, and 

 covered by a thin and transparent pellicle. This fluid becomes less 

 and less transparent, until it acquires the colour and consistence 

 of pus. The pustule during its serous state is of a rounded form. 

 It is flattened when the fluid acquires a purulent character, and 

 even slightly depressed towards the close of the period of suppura- 

 tion, and when that of desiccation is about to commence, which 

 ordinarily happens about the ninth or tenth day of the eruption. 

 The desiccation and the desquamation occupy an exceedingly 

 variable length of time; and so, indeed, do all the different 

 periods of the disease.' 



Mr. Youatt advises the ordinary treatment for febrile disease, 

 viz., a warm, airy, loose box, and protection from any sudden 

 change of temperature, which he says is almost invariably fatal. 

 As in the human subject, pneumonia is a very common complica- 

 tion of small-pox, and must be treated by bleeding, &c., vigorously,
