THE OCEAN WORLD. 
suckers, each arm of the cuttle-fish carries about two hundred and 
forty, the total number being nearly a thousand. The mouth we have 
already described, iu Dr. Roget’s words : “ The teeth move vertically; 
much as the cutting edge of the two blades of a pair of scissors move 
upon each other, tearing the prey by the assistance of their hooked 
terminations.” 
The tongue is covered on its upper part by a thick horny bed, 
bristling in the centre with a series of recurving teeth, while its edg 0 
is armed with three other erect teeth, which are slender and hooked' 
The oesophagus is long and slender. At the abdomen the gullel 
expands into a sort of frill, to which succeeds a gizzard, with strong, 
fleshy walls ; and, finally, a very short intestine, which directs itself 
forward, terminating on the median line of the body. Towards th 0 
anterior parts is a cavity, of which a few words must be said. ® 
occupies the free space comprised between the exterior surface of tb e 
abdomen and the internal faeo of the mantle ; and here the resp 1 ' 
ratorv organs, namely, the brmehise, are lodged. Here, also, are th e 
reproductive and excretory organs. 
The branchiae, which are two in number, are voluminous, but short, 
tufted, and leaf-like. The branchial cavity can dilate and contra 0 ! 
itself alternately. It communicates externally by two openings : th e 
one, fashioned into a cleft, receives, while the other, which is p r °' 
longed into a tube, serves to eject, the water, and becomes a power ! 11 
organ of locomotion. 
The inspiration of the animal is thus made by a cleft in the mantl 0 ; 
and expiration by the tube : the renewal of the respirable liquid act 0 
as a sort of sucking and forcing pump, at the surface of the lamella 
branchials. The cuttle-fish, in short, will be at no loss to reply t0 
the question of the Don Diego of Corneille — 
“ Rodrique, as-tu du casur ?” 
for they have three hearts. The two first are placed at the end 
the branchiae. With each beat of the pulse the venous blood 1 
brought from all parts of the body, and propelled through each S 
or branchue. Vivified by respiration in the internal tissue of 1 1 
branchiaq it is carried by the veins into the third heart, situated 11 P C ’ U 
the median line of the body ; and now the regenerated fluid is ag alU 
distributed throughout the rest of the economy.
