Invasion of the Nasal Cavity by a Leech *Rearranged by the Editor, I. M. G.[Comment.—We submitted Dr. Astavans' note to Dr. C. Strickland, Professor of Medical Entomology, Calcutta School of Tropical Medicine, who has kindly commented as follows:—"With reference to your endorsement on the attached paper, Dr. Roy identified the leech as Dinobdella ferox, but awaited Professor Moore's return to Calcutta for confirmation. This I have now obtained.The interest of the paper must be judged by existing records of infestation of the respiratory passages of man by leeches in general and D. ferox in particular. As for the former there are many, the majority of which seem to have been in Egypt and nearby countries due to Limnates spp.As for the latter there have been no previous records of such a case in man, though the nasal cavity of cattle is the normal habitat of the species. The history given by the writer is in accord with the usual history in animals."—Editor, I. M. G.]

He also suffered from occasional epistaxis. On examination I could see the worm, but it was rapidly lost to view in the naso-pharynx. I, therefore, definitely concluded that the worm was there and awaited its reappearance with an artery forceps in my hand ready to secure it, but I was disappointed for it did hot appear for about 15 minutes. I then applied a turpentine swab to his nostrils, and placed my index finger firmly over the orifice of the naso-pharynx at the same time asking my assistant to douche out the nasal cavity with potassium permanganate lotion. The worm slipped up and down, two or three times but ultimately it was caught in the artery forceps; it appeared that the worm was of enormous length. Subsequently it was extracted after a forcible pull and left in a tray of water where it remained alive for two days. The worm measured
