CLASS MAMMALIA. 69 near Romford, in November, 1865 (Field, Nov. 25 th, 1865, p. 377). In the Supplement to Daniel's Rural Sports (London, 1813, 4to, p. 480), there is an account of a Hare being run down by a single dog, a cross between a Hound and a Spaniel—and that a nearly blind one—at Great Baddow in December, 1808. The chase was for a wager. The same author gives (vol. i., p. 548) the details of a very long course near Felstead, in February, 1789. Both occurrences are of some interest, as showing the amount of sport afforded by this creature. Lepus cuniculus, Linn. Rabbit. This destructive creature is very common in all parts of Essex, and little need be said about it. Its food, habits, and appearance are sufficiently well- known to all dwellers in the country. It may not, however, be so well-known, that occasionally specimens occur, which in colour are quite black, or white, and this, I believe, without any admixture of tame blood. Mr. Reginald W. Christy gives (Essex Nat., vol. ii., p. 33) a description of several black Rabbits that he observed at Roxwell. Mr. E. A. Fitch describes (ibid., vol. iii., p. 25) a litter of albinos found at Hazeleigh. In neither instance does there seem any reason to suspect a cross with a domesti- cated parent. There are, in the large warrens of the counties of Norfolk and Suffolk, any number of silver-grey rabbits. I do not hear of any of this variety in Essex, unless the black ones mentioned by Mr. R. W. Christy, may be sports in this direction, for the young silver-grey animal is generally black in its first coat.
