    rately, must necessarily yield different results; but as this deli- cacy of chemical manipulation is difficult, if not impossible, we look only to the analysis of all the constituents, in the aggre- gate, which are found in tubercle. As a first and general proposition it may be affirmed, that tubercle, in its ordinary forms, consists largely of animal matter. Thus Thenard found solid tubercle to consist of 98.05 animal matter; chloride of sodium, phosphate of lime, carbonate of, lime, 1.85; and some traces of oxide of iron. Hecht-found in six grammes of tuberculous matter: albumen, 1 gramme, 4 decigr.; fibrin, 2 grammes, 8 decigr.; gluten, 1 gramme, 2 decigr. Preuss found 19.5 per cent, of solid matter, 80.5 water; the solid portion consisted of an animal matter which gave the reactions of casein, a fatty substance containing cholesterine, and a small quantity of salts.* The nature of the animal matter is a subject of dispute. ANALYSIS OF SOLID TUBERCLE. Let us turn first to the ultimate or elementary analysis. The following result was obtained by Scherer, in an analysis of crude tubercle :f Carbon 53.888 1 Hydrogen 7.112 I Nitrogen 17.237 | ~ iUU Oxygen 21.767 J 100.004 The formula for this analysis is thus expressed: C43, H35, N6, 013. The analysis of tubercle obtained from different parts of the body, according to Scherer, exhibits a remarkable uniform- ity of composition, as will be seen by the following table.J Tubercle from the lung C;3 H!5 N6 013 Tubercle from the liver C43 HM Ne 0M Tubercle from the peritoneum CM H38 Ne 0]3 Tubercle from the brain C48 Hs7 N„ 013 Tubercle from the mesentery €« Hgg Na 013 * Glover on Scrofula. t Simon's Chemistry. % Ancell.
