The treatment must be regulated by circumstances, but the principal indication is to remove the remote causes in the early stages, and to obviate the effects in the latter. If active inflammation be going on, bleed and blister; and if tumefaction of the neighbouring parts have occasioned it, attempt their reduction. Elevate the head as much as may be. Mr. Sewell recommends a seton in the neighbourhood of the obstruction when known; and in desperate cases he observes, that tracheotomy has been performed with considerable advantage; but the extreme difficulty of detecting the exact situation of the obstruction, will prevent its being generally adverted to.—Blaine.
Rock-doe, s. A species of deer.
Rock Pigeon, s. (Columba livia, Brisson.)
Ornithologists seem to differ in opinion concerning the rock and stock pigeon; though it appears almost impossible to conceive them a distinct species. In those described under such names there seems to be so much similitude, except what may be expected from a species half reclaimed, and frequently returning to their natural wild habits again, that we cannot but consider them as one and the same species.
The rock dove is considered to be the origin of our tame pigeons, as it is said to possess the white on the lower part of the back, in which part the stock dove is described to be ash-coloured, and that this last is rather larger. But these variations we have observed in pigeons killed in their native haunts amongst the rocks on our coasts; and our dove-cote pigeons frequently have no white on the back. It is therefore probable many of our common species, after having been bred in a pigeon-house contiguous to such rocky situations, return to their natural habits, and there produce some variation in colour.
The bird now before us we killed on the cliffs in Cauldy Island, in South Wales. It weighed eleven ounces; length thirteen inches and a half; breadth twenty-two; the bill is brown, inclining to purplish-red; point dusky; irides light yellow; the head dark bluish ash-colour; neck and breast glossed with green and copper, as viewed in different lights, most conspicuous on the sides and back of the neck; the upper part of the back and wing coverts pale ash-colour; across the middle of the greater coverts is a broad band of black, and another of the same on the ends of the secondary quills, running into each other on those feathers nearest the body; the greater quills are dusky, dashed with ash-colour, the outer ones darkest, and all of them most so towards the tips, slightly edged on their exterior webs with white; the lower part of the back white; the rump and tail dark bluish ash-colour, the ends of the latter black; the two exterior feathers whitish on the outer webs towards the base; the sides under the wings, and under wing coverts, white; the belly bluish ash-colour; legs red.
These birds have sometimes appeared in prodigious flocks in winter, frequenting our beech woods for the sake of the mast or seed of that tree. These flights, however, are less numerous and less frequent of late years. Sometimes they are seen in company with our common pigeons, at the barn doors, in severe winters; and are said to be known by their inferior size and darker colour.
The only place where I have ever seen the rock dove in a wild state, was at Howford, near Mauchlane, in Ayrshire, where two or three pairs nestled on the cliffs of the romantic rocks overhanging the river, but in situations so inaccessible, that I never knew them robbed by the most daring boys. It would be hard to say whether these had strayed from some neighbouring dove-cote, or had originally come thither from some wild brood; though the former is not so probable, as instances, I believe, are rare, of domestic pigeons voluntarily deserting their birth place.—Montagu—Rennie.
