    The following results were obtained by Dr. Glover, in a series of analyses :* c. h. n. o. 1. Crude granular mesenteric tubercle 54.97 6.63 12.31 26.09 2. Crude granular mesenteric tubercle 56.40 15.56 3. Crude tubercle from lung 53.43 6.64 14.02 25.91 It will be observed that these analyses furnish a close resem- blance to the composition of the so-called protein compounds, and, therefore, that tubercle bears a relation to protein. Taking Liebig's formula as the basis of the hypothetical substance denominated protein, we have the following: C48 Ha, Na 014 Albumen, however, being the basis of those substances known as protein compounds, constitutes the proper physiological product with which we may compare the pathological substance known as tubercle. The following is the composition of albu- men, as given by Scherer and Mulder: Soberer. Mulder. Carbon 54.9 53.5 Hydrogen 7.0 7.0 Nitrogen 15.7 15.5 Oxygen ] T22.0 Sulphur [• 22.4 \ 1.6 Phosphorus J (. 0.4 100.0 100.0 It will be observed that, taking Scherer's analyses for com- parison, there are marked differences between the elementary composition of tubercle and albumen, which will be the more evident when brought into juxtaposition, thus: Albumen. Tubercle. Carbon 54.9 53.888 Hydrogen 7.0 7.112 Nitrogen 15.7 17.237 Oxygen (Mulder) 22.0 21.767 Suiphur (Mulder) 1.6 Phosphorus (Mulder) 0.4 * Pathology, etc., Scrofula.
