The author, in a monograph of two hundred and fifty pages, discusses the literature critically, classifies gliomas and paragliomas on a histogenic basis and gives a detailed description of the various types. He believes that the work will be of value in that the descriptive material is based entirely on preparations made with a single technic, that in which silver carbonate and its various modifications are employed. He defines glioma and paraglioma, stating that the neuroglial network of the nervous system only, exclusive of the meninges, endoneurium and perineurium, is truly neuroglial and capable of forming gliomas. He excepts the cells of Schwann, which he considers equivalent to oligodendroglia and which are therefore, theoretically at least, capable of forming peripheral gliomas. He includes under the term paraglioma tumors formed by neuroblasts and ganglion cells and those derived from the germinal cells of the epiphysis and from the epithelium of the
