The Force of Habit. Some time since, Lowndes, a tippling bookseller, presented a check at the banking house of Sir William Curtis & Co., London, and upon the cashier putting the usual question, “How will you have it?” replied, “cold, without sugar.”

The Narval, or Sea-Unicorn.

Among all the variety of weapons with which nature has armed her various tribes, there is not one so large or so formidable as the tusk of the narval. This terrible weapon is generally found single, and some are of opinion that the animal is only furnished with one by nature; but there is ample proof of instances to the contrary, for a narval with two teeth was for some time to be seen at the Stadthouse, at Amsterdam. The tooth, or horn of the sea-unicorn, is as straight as an arrow, is wreathed, and tapers to a sharp point; and is whiter, heavier, and harder than ivory.

The form of the sea-unicorn, as may be seen from the engraving prefixed to this article, resembles that of the dolphin, the head being about the seventh part of the body; the mouth is exceedingly small when compared to the enormous bulk of the animal, the eyes keen, and the nostrils placed on the top of the head.

The narval varies in color according to age; when young, the back is grayish, with small spots of a dark hue; and when full grown, is whitish, with small brown or gray spots, which vary much in their depth of color.

The sea-unicorn is generally found about Greenland and Iceland, but it is said that one has been seen near Boston. They swim with great rapidity, and are rendered formidable by their tusks, which they sometimes bury in the sides of a ship, or in the body of the whale. They are generally seen in numbers, and whenever they are attacked they crowd together in such a manner that they embarrass each other by their tusks.

“We one day saw,” says Scoresby, in his ‘Voyage to Greenland,’ “a great number of narvals, that swam near us in parties of fifteen to twenty; the majority of them were males, and had very long horns, or tusks, and seemed to be enjoying themselves by raising their horns above the water, and crossing them as if fencing. During their play they made a very strange noise, as if water were gurgling in their throats, which was probably the case, as the noise was only heard when they lifted their heads above the water. The greater number, apparently attracted by curiosity, followed the vessel, and as the water was clear, we could plainly see them go down to the keel and play with the rudder.”

The narval lives upon small fish, and not, as Cravez has asserted, upon sea-plants. Scoresby, in the following passage, confirms our statement:—

“My father sent me the contents of the stomach of a narval, which appeared to me very extraordinary. It consisted of small fishes half digested with the bones and fins of others, besides the fragments of cuttlefish, which seemed to constitute its principal food. There was a part of the back-bone of a turbot, fragments of another, with one almost entire—this was about two feet three inches long, and one foot eight inches broad. It is strange that the narval, without teeth, and having a very small mouth, apparently inflexible lips, and a short tongue, is able to seize and swallow a fish about three times larger than its mouth. As the animal in which these extraordinary contents were found was a male, with a tusk of seven feet, I think that this weapon had been used to catch the fish which had recently been made his prey. It is probable that the turbot had been pierced and killed before devoured, otherwise it is difficult to imagine how the narval was able to seize it, or how a fish of such activity as the turbot would allow itself to be taken by one with smooth lips, without teeth to catch, and without the means of holding it.”
