Size of Heads and BrainPower.
In an article m jfche " Popular Science Monthly," Dr M: A. Sl>arr s^ys that "there are many interesting facts which make one believe that the greater the extent of brain surface m man, or, to put it a little differently," the more the folds and deeper the cresses between them, the greater is the 'tnan's mental power ; and just here it becomes apparent that to judge of the extent of the entire brain surface by the size of the head, or by the extent of the superficial, irregular surface which is covered by the skull, without any regard to the number of folds of their depth, is to fall into an absurd error; and here we bea;m to see how baseless the old phrenology Teally is. For a little brain with many deep folds may really, when spread out, have a larger surface than a large brain with a few shallow folds, and a so-called bump or elevation on the apparent surface of the organ, even if it produce a corresponding elevation on the head, which it frequently fails to .dp, :>will indicate nothing regarding the number of folds or the depth of the creases which lie about it, so that it may be stated without hesitation that from the size or shape of the! head no conclusion whatever can be made as to the extent of surface of the brain, and consequently no conclusion can be reached regarding the mental capacity." In short it is not the size of brain that is the guage of power, but the number and extent of the convolutions.
