Hut, whoever ia convinceil of the jiaraaitic natuit? of the infective kinds of virus, will not hesitate to lailieve in the airpuscular nature of the tulierculous fwison also, and w'ill so remain in con- fident expectation that, in a not too distant futun?, proof will lie furnished of the existence, in the interior of tuliercle-mKlules and scrofulous products, of specific cor|>uacular elements which tho.se who arc fond of hi.storical names may again designate as ‘tuliercle- corpuscles.’ »So long, however, as this end is not reached, then; is no other sure criterion for tulierculosis than its infectivcnes.s.” The minute organi.sm, when found, will probably turn out to have a close family likeness to some other minute organisms, and its value as a morphological test may not be so great as the seekers for it expect Hut as reganls our existiiig means of ana- tomical or mor|)hological definition, it is hard to agree with * Cohiiheini, Dir.
