    A change of title from “Protozoa and Disease” of four preceding books to “Protists and Disease” has become necessary by reason of my having found that the pathogenic organisms dealt with are not protozoa, but protists allied to Synchytriaceae. In other words, in making comparative study of alien bodies that abound in the lesions of molluscum contagiosum, cancer, and other diseases, we have examined protozoa with great care when we should have given the closest attention to every detail of the life-history of certain vegetable protists, especially Synchytriaceae and some Olpidiaceae. But in spite of our having searched in the wrong depart¬ ment of biology the nature of cancer, smallpox, and other human diseases would before now have become plain to all, had there not been some weakness in the foundations of biology. The nature of this weakness is not obscure: it consists in a serious defect in the cell-theory, a defect the bearing of which is shown in chapters of this book, and which may also be briefly outlined here. If we bear in mind that the word “nucleus” denotes a morphological conception, the cell-theory in its present
