vessels, that the smallest puncture 

 cannot be made in any part of 

 it, without occasioning pain and a 

 discharge of blood. It is that part 

 of quadrupeds of which leather is 

 made. The cutis can be entirely 

 dissolved by the action of boiling 

 water, and consists chiefly of gelatin, 

 from which circumstance it is a 

 principal article in the manufacture 

 of glue. 



CU'TTLE. | The sepia of Linn&us. 



CU'TTLE-FISH. } A species of Cepha- 

 lopoda, genus Mollusca. The bone 

 of the sepia (which is an internal 

 bone, flat and broad, somewhat 

 resembling a sole in its appearance,) 

 is found, commonly, washed up on 

 our coasts, and when ground into 

 fine powder is used as pounce, and 

 is sometimes employed in the mak- 

 ing of tooth-powder. The sepia 

 attains to an immense size in the 

 seas of India and China, and it is 

 said that its arms, which are eight 

 in number, are sometimes several 

 fathoms long, so that it will, by 

 throwing them around a boat, 

 endanger the safety of the boat's 

 crew, and that it is usual to keep 

 on board a hatchet for the purpose 

 of severing them on such occasions. 

 Thecuttle-fishhasno external shell, 

 but is protected from its enemies 

 by a peculiar internal provision, 

 consisting of a bladder- shaped sac, 

 containing a black and viscid ink, 

 soluble in water, the ejection of 

 which, by rendering the surround- 

 ing water opaque, conceals and 

 defends the animal. The sepia has 

 its feet around its head, and walks 

 along the bottom of the sea with 

 its head downwards. The feet are 

 lined internally with little round 

 serrated cups, or suckers, by which 

 the animal both seizes its prey 

 and adheres to other bodies. The 

 mouth, which resembles a parrot's 

 beak, or the bill of a hawk, is 

 placed in the centre of the arms. 

 The ink of the cuttle-fish is said to 



form an ingredient in the composi- 

 tion of Indian ink. 



Professor Buckland states, in 

 describing the ink found in a fossil 

 ink-bag of the cuttle-fish, " So 

 completely are the characters and 

 qualities of the ink retained in its 

 fossil state, that when, in 1826, I 

 submitted a portion of it to my 

 friend Sir Francis Chantrey, re- 

 questing him to try its power as a 

 pigment, and he had a drawing 

 prepared with a triturated portion 

 of this fossil substance, the draw- 

 ing was shown to a celebrated 

 painter, without any information 

 as to its origin, and he immediately 

 pronounced it to be tinted with 

 sepia of excellent quality." 



The common sepia used in draw- 

 ing is from the ink-bag of an 

 oriental species of cuttle-fish. 



CY'ANITE. (from /oWos, Gr. color 

 c&ruleus, or sky-coloured.) Called 

 also Kyanite, and by Saussure, 

 Sappare, is a mineral of a grey, 

 blue, and blueish-green colour. It 

 occurs regularly crystallized, as 

 well as massive and disseminated ; 

 the form of the primitive crystal is 

 an oblique prism. Its texture is 

 foliated; laminaa long; fragments 

 splintery. It feels some what greasy. 

 Before the blow-pipe it becomes 

 almost perfectly white, but it does 

 not melt. Its constituent parts 

 are, alumina 64'30, silica 34'33, 

 with a trace of oxide of iron and a 

 very small portion of lime. 



CY'ANOGEN". (from KiWos, blue 

 colour, and ^ewdw, to produce, 

 Gr.) A colourless gas which burns 

 with a purple-blue flame. It is the 

 essential ingredient in Prussian 

 Blue. 



CYA'THIFOBM. (from cyathus and 

 forma, Lat.) In the form of a cup, 

 or drinking-vessel ; cup-shaped. 



CYATHOCBIHI'TES. (from icvaOos, a
