On pressing these glands a small quantity of a whitish, viscid, oleaginous matter escapes. They open on the internal surface of the stomach & are lined by a prolongation of the mucous membrane. Their other ex- tremities swell into a small ampulla. & the little glands are loosely connected by cellular substance. This struc- ture as far as I am acquainted is peculiar to the Lin mean genus Pelecanus. I am of [the] opinion that it is merely a very well developed state of the mucous follicular glands, & that the small auxiliary glands on the stomachs of the Procellarige is merely a smaller development of the same structure. This stomach terminates in the gizzard, which is nude, firm, and muscular. The convolutions of the great intestines are numerous. The pancreas is a long narrow body attached to the intestines. The liver is large & divided into two nearly equal lobes, that of the right side is a little larger & divided into smaller lobules. The structure of the animal enables it to fly to immense dis- tances, & one sees in this bird the structure of an eagle, as far as the organs of motion are concerned, & in respect to organs of digestion a true pelican. From the extrem- ity of the wing to the tip of the other measures 7 feet & they are moved by very powerful muscles. The sternum is round & acute & differs in no essential from that of the genus Falco. On the other hand its short feathery legs [are] furnished with very weak muscles & its unpalmated feet would indicate that it is not formed for swimming or diving. 15. These few days past the air has become much more cool in consequence of the frequent showers we have ex- perienced. In consequence of the blowy weather numer- ous individuals of the genus Sula have taken refuge on board the vessel, & easily allowed themselves to be taken.
