This Table shows that muscular tissue in consumption con- 

 tains rather more than twice as much chlorine and consider- 

 ably more soda than it does in health ; and from what has 

 been stated above, it follows that muscular tissue in phthisis 

 yields more water, and is moreover wetter than healthy flesh, 

 the proportion of water being 154 for 200 of flesh in health, and 

 166*5 after death from consumption. Now chlorine and soda do 

 not enter into the composition of the completely assimilated mus- 

 cular tissue ; they form part, however, of the constituents of 

 muscles ; and it will be interesting to consider how their increased 

 proportion in the muscles of consumptive patients can be ac- 

 counted for. The various constituents of flesh, in health, in- 

 cluding the water, may be considered to be supplied from the 

 blood in the form of molecules, each of them containing certain 

 proportions of these constituents, which may vary in quantity 

 within certain limits. The water, however, is subject to very 

 slight variations, its proportion of 77 per cent, being very tole- 

 rably constant. This water binds together in the colloid form the 

 other material which enters into the composition of flesh, so that 

 the constituents of healthy muscle are not wet from the pre- 



* These chlorine determinations were made by dialyzing for tvventy-fonr 

 hours a known proportion of the watery extract of a given weight of flesh. 

 A portion of the fluid outside the dialyzer was then evaporated to dryness, 

 and the residue was incinerated, the chlorine beiog determined volumetri- 

 cally in the solution of the ash. It was finally calculated for the total vo- 

 lume of the fluid (in and out of the dialyzer). This may be considered as 

 giving very correct results, twenty-four hours being long enough for chlo- 

 rine to diffuse out of a dialyzer proportionally to volumes. Chlorides may 

 be safely considered as never being colloid.
