Note 292 — ON PARASITES IN GENERAL. (continued 8)

In Iceland 28 per cent. of the dogs are infected with this Tænia, in Lyons 7·1 per cent., in Zurich 3·9 per cent., in Berlin 1 per cent., and in Copenhagen 0·4 per cent. In Australia even 40 to 50 per cent. of the dogs are affected. It is, however, a question whether, in addition to Tænia echinococcus, a second analogous form is not involved, as the form from Canis dingo attains a length of 10 to 30 mm.
