General Observations on the Balænidæ.
The entire form of the animals so nearly resembles a fish, as to lead the naturalist, and practical whaler, to insist that the Cetaceæ are fishes; nothing but the researches of the anatomist could have rescued the whale from that class.
The exhibition of the great Rorqual, at the Royal Institution, in 1835, was considered by the great mass of the visitors, as a sheer imposition. They wished to see the skin stuffed. The baleen (in that case in sitû) was disbelieved to be a reality by most persons who visited the exhibition. One or two persons actually demanded a return of the admission fee. Yet to the anatomist, the contemplation of the spinal column (trunk) composed of sixty-five vertebræ (out of many of which the entire skeleton of the ox could have been fashioned), and these connected by sixty-five joints, many of them containing a gallon of joint-oil, presented a lever, or rather a whip-shaft, to the tail, which left no doubt of the effects of the application of its distal extremity to a whale-boat.
I remember a whaler of the name of Thoms, residing on the Island of Kapiti, who was merely touched by the tail of a Mysticete, and nearly every bone on one side of the body was broken. Fortunately, there was no “duly qualified doctor” to be had, and Thoms consequently got quite well, with the exception of a slight lameness. When brought to the station, he was lifted out of the boat with considerable difficulty, being literally glued to the boat by the blood lost.
The sternum, also, is remarkably short, having only two or three pairs of ribs connected to it. Now, this, instead of indicating a rudimentary condition, rather proved the Divine perfection in all nature's works. In consequence of the smallness of the sternum, the great respiratory muscle— the diaphragm—measured in the great Rorqual, 60 feet in length, by an

average breadth of 10 or 12 feet; thus enormously increasing the capacity of the chest at the will of the animal, either thereby depressing the locomotive power, or increasing it when determined on a rapid journey.
It has been demonstrated by the comparative anatomist, that the Mysticetae, and, in all probability, the Rorquals, at an early period of uterine development, have numerous cone-shaped teeth, unfilled, for their future existence. These teeth, accordingly, never proceed beyond the first stage of development, and the young cub at birth, is a sucker. The palate, soon after birth, becomes covered with numerous transverse ridges, and a white horny substance begins to spring from them, lengthening with the growth of the animal, and corresponding to the development of the jaws, longest where the arch of the upper jaw is greatest, and diminishing towards the throat and snout, to mere hairs. Thus, the animal destroys myriads of minute mollusca, and even microscopic marine insects, which, from their enormous increase, might become the source of pestilence, had it not been for their wholesale consumer.
