Cutting-In a Right Whale or Bowhead.
A-Fluke-chain adjusted to the "small."
B-Fin-Chain fastened around left fin.
C-Ring of fin-chain into which blubber-hook is fastened to raise fin and blanket-piece (the starting point when unwinding blubber from the whale).
D-Hole in root of lip into which blubber-hook is inserted to hoist lip on board ship.
F-G- Scarf to detach and hoist lower lip.
E-H- Scarf cut from fin below and forward of eye to blow-holes H on head.
E-I- Scarf from fin E to back of whale I.
J-K- Scarf cut in removing blubber while whale is being rolled. (The other spiral lines show final scarfs.)
L-Hole mortised in head for head-chain.
M-One method of hoisting head by head-chain and toggles, the chain being pasdsed through the blow-holes.
M, M (Fig.2).-Newer and better method of hoisting head by use of chain strapped blocks. Tail of chain passed through from H, under several feet of blubber to and through the hole cut at L and then coupled to sister-hooks on the lower block.
N-Cutting made by man with an ax (while overboard) in order to detach the head bone.
O-Lower edge of bone which is very thin and requires only light strokes to free it.
P-Markings showing where the spade is inserted to start the throat bone in detaching head.
Q-Where the hole is made in throat in order to haul it on board.
R-Throat-chain and toggle by wihich throat is sometimes taken on board.
S-Dotted line to show where backbone is cut to lessen strain on windlass when taking off lbubber.

Right Whale and Sperm Up to 60 Feet Finners Up to 110 Feet
1-Greenland Right Whale, Balaena Mysticeptus, up to 60 feet in length, generally found near Arctic ice. The smaller whalebone whale of the Atlantic and Southern oceans is somewhat similar in shape; it runs to 50 feet; shows tail as it dives; has no fin on back. It is called the Nordcapper or Biscayensis and Australis. 2- The Sperm or Cachalot,; Physeter Macrocephalus. A toothed whale 50 to 60 feet;; shows tail when it dives; sometimes breaches,; i.e. leaps several times in succession as it travels; blast low and projected forward. 3- Seihvale, Balaenoptera Borealis, 40 to 50 feet; blast about 10 feet; does not usually lift tail out of water before final dive; has fin on back, is therefore a "finner.; 4- Fin whale, Balaenoptera Musculus, up to 75 feet. The Blue whale Balaenoptera Sibbaldii is similar, with smaller fin on back; both make blasts about 18 feet. The Blue whale in Southern seas has been killed up to 110 feet.

5-Paralichthys albiguttus, on very fine gray sand, almost entirely covered with sand, from August 19 to 21. Note the two small depressions in the sand at the base of the caudal fin. The lower one is much more prominent than the other. This individual breathed only through the lower gill. The water which entered the mouth passed back under the body and oozed up through the sand, forming the depressions. The animal was very effectively concealed. 6-Same individual uncovered.... 7- Paralichthys, 13 cm. long, in a glass dish over very fine black sand. Note the remarkable similarity between the pattern and the shade in the fish, especially the central part of the body, and those of the sand. The tips of the fins and the tail have no pigment and consequently stand out boldly against the background. 8- Paralichthys albiguttus, 16 and 10 cm long, on a smooth jet black background. Note the conspicuous white spots. In some instances all of these, except a trace of the one at the base of the pectoral fin, disappeared entirely

Solea vulgaris : General view of the musculature of the common sole seen from the right side, after removal of the skin. The superficial abductors of the ventral fin have been removed, to expose the elevators and depressors of the ventral fin-rays which lie beneath them; the same dissection has been made along the anterior fourth of the dorsal fin
