And, in the second place, as it is well known, that the chyle mixes with, and becomes blood itself, very shortly after it is poured into the blood vessels, the milk, and other foreign matters united with it, would then be deserted, and would be left in that same undiluted state, in which they have been in- jected into the vessels, and in which they kill. As to the chemical change, which these foreign matters are supposed to undergo, in the lacteal and lymphatic vessels, that will be readily admit- ted. It is just one of the propositions we wish to maintain. We wish to establish, that all matters, capable of forming chyle, must be reduced to that state previous to their entrance into the circula- tion; and if they will only grant this, they shall have our free consent to call the change, a chemicalone. If, therefore, any substance causes death, &c. when injected immediately into the blood vessels, it follows, of necessity, that that substance, pro- vided it be in the same form, will always produce the same effect, let the mode of introducing it into the circulation be ever so much varied. We will avail ourselves of this reasoning on a subsequent occasion, to extricate us from a difficulty. We do not mean, however, to insinuate from this, that some other substances may not be thrown into the blood-vessels, and may not exist there without much danger. This inference would be opposed by facts, and one of a very remarkable <£ Z/e^lv erf fy*tC***Jy /*riL*<s ^& ¥£~ /£>-**+ **£
