by Delore (1864) and Giacomini (1874). In M. Delore’s case, about 2000 were obtained post mortem. Of these, 111 occurred in connection with the nervous centres, eighty-four being in the cerebrum, twenty-two in the membranes of the brain, four in the cerebellum, and one within the substance of the medulla oblongata. Dr Knox published a less notable instance in the ‘Lancet’ (1838); and in the year 1857, Dr Hodges, of Boston, U.S., published a case where the cysts, which in size he compared to rice grains and coffee beans, were felt subcutaneously. The coexistence of Tænia and Cysticerci in the same individual has also recently been observed in France (‘Lond. Med. Rec.,’ 1875). Besides these, several remarkable instances have lately been reported by Davy, Tartivel, and others.
