 much serum. 



On analysis of the cutaneous excretion it was found that 

 it contained large quantities of nitrogen in the form of ammonia,

a small proportion as urea, a proportion as albuminoids, about 5 

 per cent, of fat, and also salines in the form of phosphate, sul- 

 phate, and chloride of sodium, with a little chloride of potassium, 

 and the proportion of water as low as 10 per cent. It was 

 noticed that there was a large proportion of volatile butyric, 

 and a small amount of lactic acid. It will be seen from the 

 photo-micrographs that the papillae of the skin are hypertrophied
