Not illustrated. 1917 edition. Excerpt: ... as before. Make the stabs practically continuous so that the brain can be broken apart along the line of these stabs. This procedure is easy to carry out and can be done very accurately. Each cerebral hemisphere will now have been cut into four pieces, to be called frontal, parietal, occipital and temporal pieces. These pieces are to be weighed separately at first, and then the parts of each hemisphere are to be assembled and weighed together in order to get the corrected weight of the hemisphere as a whole; this weight must equal the sum of all of the parts if these parts have been correctly weighed. If brains are not carefully fixed, so that their natural shape is preserved without distortion, it is obvious that the cuts as above described will not pass through the same parts of each brain and that the pieces, consequently, will not be strictly comparable one with another. The object of this gross weighing-of brains in well-established cases of dementia pnecox is to determine whether in this disease any special part of the brain is out of proportion to other parts, or out of proportion to the same parts taken from a normal brain. In order to have this work mean anything, brains from other psychoses, or from normal cases, must be similarly cut and weighed so as to be compared with the dementia prsecox material. If, for example, the frontal segment of the brain should prove to be especially light in dementia precox, this would be an indication for special work on this part. The method is admittedly rough, but if a large number of well-preserved brains is studied in this way by the different hospitals, and the results are brought together, individual errors will be somewhat neutralized. Incidentally, some information may be gained by this more
