[L. collocutus (pp. of colloqui, speak together: see colloquy ) + -ory.] Pertaining to or having the form of a colloquy or conversation; colloquial. [Rare.] We proceed to give our imitation, which is of the Amœbean or Collocutory kind. Poetry of Antijacobin , p. 10. Collodaria (kol-ō-dā'ri-a), n . pl . [NL., κολλώδης , viscous, like glue (see collodion ), + -aria .] A group of spumellarians without a skeleton, or with a rudimentary one composed mainly of detached silicious spicules scattered outside the central capsule; a suborder proposed by Haeckel for the families Thala icol lidæ, Collozoidæ, Thala osphæridæ , and Sphæ rozoida . collodion (ko-lō'di-on), n. [NL., also collodium , κολλώδης , like glue, κόλλα , glue, + είδος , semblance.] A substance prepared by di olving pyroxylin or guncotton in ether, or in a mixture of ether and alcohol. It forms a useful substitute for adhesive plaster 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 bromides, collodion is employed as the basis of a photographic proce , called the collodion or wet proce . To obtain a negative picture by this proce , a gla plate is covered with a film 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 developed by the application of a solution of iron protosul phate, water, and acetic acid, and the unprecipitated tion of sodium hyposulphite or of pota ium 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 paper, must pa through the negative, and the exposure is continued till the tone is sufficiently deep, after which the tint is improved by means of gold chlorid and other salts, and the picture fixed with sodium hyposulphite. Positive pictures may also be obtained direct by the collodion proce . Collodion is used also as a water-proof coating in place of varnish, especially to protect lucifer matches from the effects of dampne . col lod ionize (ko-lō'di-on-iz), v. t.; pret. and remaining in the film is di olved by a fixing solu pp. collodion i zed, ppr. collodion i zing. [ Into this [a special solution] is dipped the proof after taking it from the water and draining it, the collodion i zed side uppermost. Pop. Sci . Mo. , XIII. 442. collop
