and reproduce by eggs, which are large, and generally found r° 
clusters, known to fishermen under the name of sea-raisins. 
Like the zoophytes, they possess the property of redintegration) 
already described, being able to reproduce any arm that may h° 
destroyed. There is another singular peculiarity which the cuttle' 
fish shares with man. Under the influence of strong emotion th e 
human face becomes pale, or blushes, and in some individuals it 
said to become blue. This has always been supposed to be an attribute 
of humanity ; but the cuttle-fish shares it with our race. Yielding t° 
the impressions of the moment, the cuttle-fish suddenly change 13 
colour, and, passing through various tints, it only resumes its fainih ar 
one when the cause of the change has disappeared. They are, in 
fact, gifted with great sensibility, which reacts immediately upon then 
tissues, these being extremely elastic and delicate. Sudden changes 0 
colour are produced — changes which far exceed the same phenomena 111 
man. Under the influence of passion or emotion man is born to blush) 
but under no sort of excitement does he cover himself with pustules , 
this the cuttle-fish does : it not only changes colour, but it covers 
itself with little warts. “Observe a poulpe in a pool of water,” sa} s 
Ii’Orbigny, “as it walks round its retreat — it is smooth, and of ver - 
pale colour. Attempt to seize it, and it quickly assumes a deeper ti» > 
and its body becomes covered on the instant with warts and hau > 
which remain there until its confidence is entirely restored.” 
Tho Ccphalopods thus constituted — crowned with numerous fl eS ^ 
arms bearing sucker disks, enveloped in a sac-like mantle, open 1,1 
front, and sometimes enclosing a rudimentary shell, with a rudim 011 
tary brain and cartilaginous skeleton, breathing by gills, which ar ® 
bathed hi water passing beneath the mantle, and discharged throng 
a tube — are divided by Dr. Loach into two families ; namely, 
poda. having two tentacles and movable eyes ; and Odopoda, with 0 
tentacles, and eyes fixed. 
The Decapoda includes the cuttle-fish, Sepia ; the squids, Solid. ’ 
and the calmars, TeutMdee. The Sepiadse have eight arms ris 11 ^ 
from the crown of the head, armed with four rows of suckers, 1 
long, slender tentacles, with broadly-expanding ends and stafn . 
suckers, eyes moving in their sockets, body broadly ovate in 
the body elongate, and a horny, flexible shell in Solicjo, and conic*
