Coagulation is a.fort of accident.in the living body, and itisnot to be believed that the acci- dental concourfe of parts fhouldform the perfect fyftem oi a living bone; nor that coagulation, an irregular uncertain procels, fhould keep pace with the growth of the living parts; that a bone which is completely organized, and a regular part of the living fyftem, fhould, in all its progrefs towards this perfect ftate, be mere inanimate, inorganized matter: Yet this opinion once prevailed; and if other theories were at that time propofed, they did not vary in any very eflential point from this firft notion.
