Broughton-Alcock and Thomson: Embadomonas intestinalis Embadomonas intestinalis (Wenyon and O'Connor), 1917; Description of the Cysts and Free Forms found in a Case in England. By W. BROUGHTON-ALCOCK, M.B.

THE author demonstrated a series of slides showing intestinal mucus crowded with Spirochata eurygyrata, fecal matter from another case showing Spirochaeta stenogyrata and a third specimen showing Spirochata eurygyrata in the mucous portion and Spiroch.ta stenogyrata in the fecal portion of the same stool. He discussed the question as to whether these are two forms of one and the same organism or two separate species of Spirochata, saying that authors appear divided upon this question. He then continued as follows:Miss Hogue, in America, has recently publisbed a very interesting article in the Journal of Experimental Medicine, December 1, 1922, describing cultures of Spirochaeta eutrygyrata but the illustrations drawn are, unfortunately, few, and are unlike the Spirochata eurygyrata as I have always seen this organism, and as illustrated by Le Dantec 1903, Fantham and others. Unfortunately, also, there is only complimentary reference to the narrow coil type of Werner seen in the fascal portion of many normal stools and obviously non-pathogenic, since it is never found in the mucous portion nor characterized by association with a dysenteric, diarrheeic or catarrhal colitis condition. As to the pathogenicity of Spirochata eurygyrata, my experience leads me to believe that it can produce a catarrhal condition with the passage of mucus containing shed degenerated epithelial lining cells, occasionally red blood cells, and, what is extremely rare such a case as was seen in a first attack with typical dysenteric symptoms and passage for three weeks of much blood with non-purulent mucus.

regard to them. But I must dissent from some of the statements which have been made during this discussion to the effect that no regular teaching whatever has been given hitherto to medical students in England in venereal diseases. Nor can I accept the suggestion that because a medical student contracts a chancre on his finger whilst attending a midwifery case, it is because his medical education with regard to syphilis had been neglected. I know of a very distinguished obstetric physician and gynaecological teacher who met with the same misadventure. Both alike, I have no doubt, were guilty of some slight carelessness or apparently trivial inadvertence. I do not doubt that the student had received much instruction from several of his teachers about the hydra-headed phases of syphilis, nor that the obstetrician I refer to was in the habit of cautioning his students and nurses against the dangers to themselves which syphilis in the mother presents, and the dangers to the infants which maternal gonorrhoea creates. Still, I feel sure that the question of improved or more specialised teaching in syphilis, as well as questions relating to the statistics, notification, registration, and segregation of persons affected with syphilis will, in the interests of public health, soon come under the careful consideration of a committee of the Royal Society of Medicine, which was recently appointed after representatives of the society had held a conference with certain representatives of the Eugenics Education Society. Some weeks ago an inquiry was set on foot by our society with the aid, and through the medium, of the Secretary of State for Foreign Affairs, as to what is being done in other countries in regard to the registration and segregation of syphilitics, and already several reports have been received from abroad. These reports, together with the information and recommendations contained in the practical and suggestive papers of Major H.
