mainly of detached silicious spicules scattered

collodion (ko-16'di-on), n . [NL., also collodium, 
< Gr. KO/./.U?!I/C, like glue, < nAMa, glue, + eliof, 
semblance.] A substance prepared by dis- 
solving pyroxylin or guncotton in ether, or in 
a mixture of ether and alcohol, it forms a useful 
substitute for adhesive planter in the case of slight wounds. 
When the solution is applied to the wound, it immediately 
dries in a semi-transparent, tenacious film, which adheres 
firmly to the part, and protects the wound or abrasion. 
With the addition of a small quantity of Iodides and bro- 
mides, collodion is employed as the basis of a photograph- 
ic process, called the collodion or wet proct.**. To ob- 
tain a negative picture by this process, a glass plate is 
covered with a nlm of collodion, which is sensitized by a 
salt (usually the nitrate) of silver, and the plate exposed 
in the camera. The latent image obtained is then de- 
veloped by the application of a solution of iron protosul- 
ph.-ne. water, and acetic acid, and the unprecipitatcd 
silver remaining in the nlm Is dissolved by a fixing solu- 
tion of sodium hyposulphite or of potassium cyanide. To 
obtain a positive picture, a sheet of paper Is laid upon 
the face of the negative In a frame, the paper having been 
sensitized by floating on a solution of silver nitrate, or by 
any other of several methods. The frame is then exposed 
to light in such a manner that the rays, to reach the pa- 
per, must pass through the negative, and the exposure is 
continued till the tone Is sufficiently deep, after which 
the tint is improved by means of gold cblorid and other 
salts, and the picture fixed with sodium hyposulphite. 
Positive pictures may also be obtained direct by the col- 
lodion process. Collodion is used also as a water-proof 
coating in place of varnish, especially to protect lucifer 
matches from the effects of dampness. 
collodionize (kp-16'di-on-iz), r. t. ; pret. and

They are distinguished by the gelatinous character of 
their hydrates. Although often largely soluble in water, 
they are held In solution by a most feeble force. They 
appear singularly inert in the capacity of acids and bases, 
and in all the ordinary chemical relations. But, on the 
other hand, their peculiar physical aggregation, with the 
chemical indifference referred to, appears to lie required 
in substances that can intervene in the organic processes 
of life. The plastic elements of the animal body are 
found in this class. As gelatine appears to lie its type, it 
is proposed to designate sutistances of the class as colloid*.
