    FURTHER RESEARCHES ON §OME PARASITIC PRO- TOZOA FOUND IN CANCEROUS TUMOURS./ By M. Armand Ruffer and H. G. Primmer. (Plate XXIII.) From the Conjoint Laboratories of the Royal Colleges of Physicians {Land.) and Surgeons {Eng.). Section A. In a former paper, published in this Journal1 by one of us (M. A. R.), in connection with Mr. J. Herbert Walker, a short account was given of the work which had already been published on this subject. We think it unnecessary, therefore, to go over this ground again, deeming it sufficient here to mention the observations which we have been able to find in the various medical journals issued during the last five months. Soudakewitch 2 has published a second paper, in which he maintains and extends his former conclusions. He describes and figures a large number of bodies discovered by him in cancer, and which he regards as intracellular parasites. Moreover, at the end of his work, he refers to the mode in which he thinks parasites may act as etiological factors in cancer. We must confess, however, that our observations do not warrant us, for the present, in accepting all Soudakewitch’s conclusions. With regard to the figures which illustrate this highly interesting paper, we venture to doubt whether all of them really refer to parasites. At any rate, we would state it as our very definite opinion that the figures (Plate XII., Figs. 5, 18, 22) described as falciform bodies are not true falciform bodies, i.e. spores. Fig. 5 refers, in our opinion, to the chromatin bodies often met with in parasites, whereas Figs. 18 and 22 are not of a parasitic nature at all. They resemble in many particulars some of the bodies described by Podwyssozki and Sawtschenko, and we shall have an opportunity of discussing them again. We notice that so competent 1 M.
