In this Tahle the result found for the albumen of the fibrous tissue in analysis 

 No. I. was introduced in Analyses II. and III. The albumen of the nutritive 

 material in analyses II. and III. is the mean of all ray determinations of albumen 

 in the extracts. 



These analyses show that, although the solid constituents of 

 flesh be deficient, still they exist in the same relative proportion, 

 or nearly so, as in healthy muscle — the phosphoric acid and pot- 

 ash of the effete material bearing to each other precisely the same 

 relation as they do in pyrophosphate of potash, namely 43 to 57, 

 the exact numbers found being 42*9 to 57"1. It follows that in 

 consumption tjaere is no actual change in the relative proportion 

 of the solid substances concerned in the nutrition of flesh. It 

 is remarkable, however, that the flesh of tubercular subjects 

 should be found to contain more water, chlorine, and soda* than 

 muscular tissue does in health. 



The proportion of chlorine and soda in healthy muscular tissue 

 and muscle from consumptive subjects is shown in the following

This is the eighth analysis of flesh which bears out my theory. 

 * Chlorine and soda cannot, apparently, be assimilated.
