    exerts no rnodifying influence upon her foster-children in so far as can be tested by the examination of a single generation. (6) It follows, if the above is true, that in case telegony be actually demonstrated, the characteristics of a primary hnsband which are transmitted to the offspring got by a secondary hnsband, can only be so transmitted through the ovarian ova of the mother, Romanes, in his work on ‘ Darwin and after Darwin,’ vol. 2, pp. 146—148, refers to my earliest experiment; he thereon i-emarks that rabbits when crossed in the ordinary way never throw inter- mediate characters, and that the experiment is clearly without significance as far as it bears upon the inheritance of acquired characters, Mr. Romanes does not give his authority for the statement that rabbits when crossed never throw intermediate chamcters, and I venture to think he was mistaken in his view; that they do produce young which are apparently pure bred of the one type or the other, and possibly both, in the same litter is no doubt true, but it is also true that some at any rate of the young got by crossing are of an intermediate character. An examination of the litters 1 got by crossing a Dutch buck with Belgian Hare does confirms this view. Habbison AMD Sons, Printers in Ordinary to Her Majesty, St Martin’s Lane-
