 twisting their heads in all directions, with most ludicrous pertinacity. In these northern regions they are so fearless of man that they will allow themselves to be approached within a few hundred paces without exhibiting the slightest mistrust. When, however, we tried to seize one of them, they threw themselves headlong into the sea, from whence, after having swum about and dived a little, they again ascended to their resting-place. Upon rocks much resorted to by sea-fowl we have observed that the Razor-bills always take possession of rents and crevices, in which they deposit their egg. Some are found under stones, and a few in holes. Each pair produces but a single egg, which is of large size, much elongated, and very variable both in colour and markings, insomuch that no two can be found exactly alike. The young when hatched are clad in a thick coat of brownish black down, with white faces. Before they are half grown they become impatient of longer confinement, and apparently excited by the noise around them, throw themselves into the sea beneath, or roll themselves over and over upon the rocks until they reach it. The parents immediately follow them, and instruct them how to obtain food. This first leap of the young is a very hazardous proceeding, and thousands, instead of falling into the water, are dashed to pieces on the stones, insomuch that at this season the foot of the rock is literally covered with their mangled remains.

THE GREAT AUK.

The (Alca pinguinus or impennis). This extraordinary bird occupied the northern regions of the Atlantic at the commencement of this century, but is now apparently extinct, owing to the determined pursuit to which it has been subjected. So abundant was it even a few years ago, that it was used in Greenland and Iceland as an article of food—at present its stuffed skin could not be bought for its weight in gold. This species is described by Fleming as a British bird, and he assures us that it not unfrequently bred in the Island of St. Kilda. The distinguishing mark of this interesting species was the rudimentary condition of its wings, for wings they must be called, presenting as they do all the parts met with in ordinary birds, but yet so small as to be quite useless as instruments of flight. The beak, as may be seen in stuffed specimens, is elongated and very high, and gently curved along its culmen; the lower jaw is deep and vaulted, but much compressed at its sides; its cutting edge from the corner of the mouth to beyond the nostrils is nearly straight, but beyond that bends downwards at an obtuse angle to the tip. The sides of the bill present several furrows towards its anterior extremity: of these, six or seven are on the upper, and nine or ten on the lower mandible. The structure of the foot resembles that of other Auks, as does the plumage. The tail is also composed of the same number of feathers. Its stature is nearly that of a Goose; its length being about thirty inches; the wings are not more than six and a half or seven and a half; the tail measures three inches or three and a half. Upon the upper surface the plumage is glossy black; on the throat blackish brown; an oval white patch is situated immediately in front of the eye. The under side and a thin streak across the tips of the secondary wing-quills are white. The winter plumage is entirely white. The beak and feet are black. The history of a bird so recently blotted out from the list of living creatures becomes a subject of considerable interest, and several writers have endeavoured to rescue from oblivion the principal facts recorded concerning its habits and mode of life. Previous to these inquiries, it was generally understood that the Great Auk inhabited all parts of the Frozen Ocean; such, however, appears not to have been the case. We have no proof that it ever visited the coast of Spitzbergen, nor has it been found on the shores of North America even at very high latitudes. It is authentically stated that it used formerly to breed on the Faroe Isles and was a frequent visitor to the Hebrides. Brüllock obtained one from the latter islands in 1812, and Fleming was present at the capture of another on St. Kilda's Isle in 1822. A dead specimen was washed ashore in Normandy in 1830, and this is the furthest point south it is known to have reached.
