    of flesh in health. On examining the muscular tissue of consumptive individuals, it will usually be observed, especially when there is much emaciation, to be wet and soft, instead of firm and dry, as in the case of death from other diseases. It therefore appears that the water in muscular tissue after death from consumption, besides being in excess, is in a less colloid condition, or, in other words, has not for the other constituents of flesh that peculiar attraction it has in health, and which binds them all together: and it would follow that the soluble colloid constituents of the muscles of consumptive subjects (those substances which become transformed into flesh) are in a less colloid condition than they would be in healthy flesh. If so, this must check more or less the formation of muscular tissue in phthisis. The water being in excess would, of course, account for a deficiency of the solid con- stituents. The following is a tabular statement of my analyses of human muscular tissue after death from phthisis. Table A. contains the result of an early series of analyses, and does not include any determination of potash.
