This half and half apportioning of effort seems reasonable also in respect of Advances in Parasitology, although once more in this volume the main emphasis is on protozoological research. However, the reviews on amoebiasis, American trypanosomiasis and trichomoniasis are deeply concerned with pathological features of the host-parasite relationship, and a review on liver involvement in mammalian malaria also indicates my belief that this area of parasitological effort merits our closest attention in
