THE METHODS OF RESEARCH, Prior to considering in detail the methods adopted for theminute examination of the brain, the student should be fullyimpressed with the conditions which render many of theprocesses applicable for other tissues quite inadmissible consistence of cerebral tissue is such that cutting finesections by the hand, either with an ordinary razor or theValentin blades, cannot be adopted with any hope of success,since the finest sections thus obtainable are useless for micro-scopic examination, which requires sections of extremetenuity. These extremely fine sections can only be obtainedby aid of the screw microtome from portions of hardened orfrozen brain. In order to modify the consistence of thetissue so as to adapt it for this purpose, various methods ofhardening by chromic acid, chromic salts, alcohol, picric acid,and osmic acid have been
