![E. IT is observed by Professor Tiedemann, that the brain of men endowed with but feeble intellectual powers is often very small; particu- larly in congenital idiotisraus. The brain of an idiot fifty years old, weighed but lib. 8oz. 4dr., and that of another, forty years of age, weighed but lib. l]oz. 4dr. The brain of a girl, an idiot, sixteen years old, weighed only lib. 6oz. Idr.* The brain of men who have distinguished themselves by their great talents, on the con- trary, is often very large. The brain of the celebrated Cuvier weighed 4lbs. lloz. 4dr. QOgr. f As in the above cases of idiocy, the weight of brain scarcely exceeds that of a new born child, it is to be presumed that by some means it has been arrested in its growth. F. MFOVILLE, in his Anatomic pathologique, • in noticing the alterations chroniques de la substance corticale gives a case which I shall again quote in his own words: J'ai observe * Troy or Apothecaries' weight, t Phil.
