Inthe bodies of those who die suddenly, as in consequence ofaccidents, suicide^ or judicial sentence (of the latter of whomI have examined three cases), they are probably never absent;and it is the same with the majority of children. In thesecases they are as numerous and as distinct as in size of the splenic corpuscles is liable to certain varia-tions in Man and in animals and has hitherto, for the most. Fig. 228.
