Letters : Rhyl, Wales, to J. Van Voorst [London] [1866] Sept. 22, 1866 Oct. 4.

The collection consists of two handwritten signed letters discussing the Record of zoological literature, begun the previous year and published by Van Voorst. Clark had ordered a copy of vol. 2 (1865). In the first letter, Clark commiserates with Van Voorst on the difficulties of finding subscribers for a new annual publication. Clark suggests that Van Voorst sell the work in parts, to attract buyers interested only in a particular subject or unwilling to pay for the complete contents. In the second letter, after having received the volume, Clark calls it a "capital work" and "important and well conducted" and says "I will mention it to 2 or 3 of my friends." He also comments"in my own subject I can detect as yet no slips whatever" on the part of the recorders.
