    T have given a more detailed account of the evidence on which I found my conclusions. I have been careful to do this as many, who have not taken the trouble to work out the subject in detail for them- selves, have questioned my facts, and, of course, denied my conclusions. The life-history of this parasite is so complicated, and its demonstration in- volves so much patient labour, that one must not be unprepared for this: a long time may elapse before accumulated confirmations have brought about the general acceptance of the facts I have described. Sceptics who have the opportunity of working ought to work and collect evidence before they contradict or offer anything but a very qualified opinion. Endemic haemoptysis and tinea imbricata are both new and interesting diseases. The short note on the parasite called after me by my friend Dr. Cobbold, I have introduced in the hope that those who have the chance of post-mortem examinations in Orientals may look for the animal. What pathological importance it may possess I cannot say; probably it will turn out to be only a helmintho- logical curiosity. The parasitic diseases, apart from any special interest attaching to them, possess many instructive and suggestive analogies to the more widely-spread and deadly zymotic diseases. Such facts as filarial periodicity, the action of intermediary hosts in the spread of communicable but non-infectious disease, the embolism of the lymph-channels by the aborted ova of the filaria—the disease of a disease, so to speak—
