There were a few enlarged lymphatics here andthere, and the subcutaneous tissue was open, loose, and containedmuch serum. On analysis of the cutaneous excretion it was found thatit contained large quantities of nitrogen in the form of ^ Fig. 121.—Liveb.

It wasnoticed that there was a large proportion of volatile. butyric,and a small amount of lactic acid.
