After seven years of painstaking study the author has succeeded in developing a method by means of which a selective stain of the neurog¬ lia can be made.The nerve cells and their processes do not take up the blue neuroglia stain; they appear yellow by contrast.The axis cyl¬ inders and nerve fibres remain entirely unstained.Of the neuroglia only the fibres and nuclei become stained', the cell bodies of the neuroglia cells remain unstained.Aside from the nuclei of the neuroglia cells tinmethod only brings out those neuroglia fibres which are especially differ¬ entiated.If there are interstitial substancesinthe central nervous system which lack such differentiated fibres, they cannot be brought in evidence by' this method.The technic of the method was given in the January number of this Journal.
