Of the fallacy of inferences drawn from an inspection of the cranium, as to the development of the different parts of the encephalon, we have an example in the assertion of Gall, that castration oc- casions atrophy of the cerebellum; a statement which has been completely negatived by the ob- servations of Leuret. tures so much as by an absence of the longi- tudinal projection of the first, or the lateral projection of the second, and by a general symmetry of the whole configuration, which ma} be characterised as oval or elliptical; such being the form presented when the cranium is viewed either facially, basally, or vertically. The distinctive characters of these three types will now be more particularly considered ; and the European type may be conveniently taken as the standard of comparison, since it is in many respects intermediate between the two others; one of these departing from it in one direction, and the other in the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Todd, Robert Bentley, 1809-1860.
