A. C. W. The yolk of an Egg is the yelk, or yellow of the egg. In Beaumont and Fletcher's Wife for a Month it is so written:

"like to poach'd eggs,

See Richardson's Dictionary, s. v.

Jarltzberg. The name Radical is only an abbreviated form of Radical Reformer, which was the title originally assumed by the political party now known as Radicals.

C. E. B. (M.D.) Dublin. The Query shall be immediately inserted, if forwarded. The former does not appear to have been received.

H. Henderson (Glasgow). Glass may be cemented for Photographic Baths, &c. with sealing-wax. We think our Correspondent would find Dr. Diamond's Collodion Process far simpler than that which he is following.
