An interest in tumors of the central nervous system, due to the development of neurosurgery and the advent of roentgenotherapy, has caused us to combine lines of research that up to the present have been followed in one or the other realm separately. This new attack, carried on over a period of more than two years, is based on material consisting of 251 tumors. We have made certain modifications in the details of the classification proposed by one of us (G. R.) with Lhermitte and Cornil in 1924. This has been carried out with the help of our personal documents gathered since that time, and with the help of the new technic and studies that have appeared recently, particularly those of Harvey Cushing, Percival Bailey and Wilder Penfield.
The classification that we propose comprises essentially the same general ideas as that formerly reported. We seek, on the one hand, to
