    are equally cases essentially consisting in the pre- sence of foreign matters in the blood, so that what is known of one series, in this quality, may be ap- plied to the other with the utmost exactness. But the evidence afforded by the former is of peculiar value and distinctness in regard to the question before us, because the matters contami- nating the blood being possessed of marked che- mical characters, and the observer being himself the conscious means of their introduction—their presence in particular parts is susceptible of being determined by direct experiment. These facts, therefore, stand to those now consi- dered, in the relation of experiment to observation. Now the whole course of recent inquiry has tended to show, that with the exception of some familiar instances of indirect action, which need not now be specified—whenever medicinal or other agents exert a special action on particular structures, these agents become accumulated in the structures thus affected, and may be recovered from their tissue in proper form, and in much greater quantity than from other parts ; and, that when this action takes effect on secreting organs, these substances are found in the fluid secreted by them in much greater quantity than elsewhere ; testifying in this case also accumulation of the active matter in the part spe- cially acted upon. In proof of this assertion, I need only refer to the valuable mass of exact observations of late made public, on the action of lead, antimony, ar-
