146 Dr. J. B. S. Jackson's Dissections of a 
close and well marked. The Fallopian tube, cut open, was 
extremely thin and delicate, its mucous coat being thrown into 
fine longitudinal folds; 2: lines transversely where it leaves. 
the uterus, and about 8 lines at the further extremity, though 
at this last part it cannot be said exactly where it terminates, 
since it finally expands into a delicate membrane, as it does in 
some other animals. The ovaries were of a flattened, oval 
form, and 3: by 13 inches ; surface somewhat fissured ; a single 
incision being made through one of them, no vesicles were 
seen. On each side of the genital fissure, and very near to it, 
was another, about 5 inches in length, at the bottom of which 
was felt the nipple. 
F. Cuvier says, (Op. cit. p. xxiv.) “On ignore le mode 
d'accouplement des cétacés souffleurs. Personne jusqu à 
présent n'en a été témoin. L'opinion la plus probable, c'est 
qu'ils s'unissent couchés tous deux sur le côté. Steller dit 
que son manatus (le Stellére) s’accouple avec la femelle 
couchée sur le dos.” Hunters opinion appears to be very 
absurd, though Mr. Beale quotes it without remark. Now, 
on this point, Capt. Chase's observations were exceedingly 
interesting, and were stated by him with full confidence. He 
informed me that he had more than once had the most favor- 
able opportunity of witnessing the act in the spermacetl 
whale, in the right whale, and in the “ porpoise ;” in the two 
first, it continues for a few minutes, but, in the last, it 1S 
almost momentary ; the position is horizontal, and not upon 
the side, nor does the female remain supine, but, being close 
to the surface of the water, they occasionally turn so a$ alter- 
nately to bring the top of the head above the water, evidently 
for the purpose of respiration. The right whale, he t mis: 
breeds at particular seasons, but the spermaceti at any season 
of the year; and he agrees with most observers in never 
having seen more than a single young one at a time about 
an old female; in cutting up one of these last, he has seen 
“a bucket-full of thick, rich milk” discharged from the
