You quite misapprehend the purport of my question. The illustrators to Dr. Risien Russell's paper are not to be done on wood but by Collotype. What I want to know is, whether collotypes can be put into the text, or must be printed as plates. Please let me have an estimate for collotypes, as well as an answer to this question.
