ON EXPERIMENTS IN INHERITANCE.

mating with the yellows, and such matings should have commenced 

 before this interim report is in print. The problem upon which it is 

 sought to throw light will, I think, be recognised as one of importance 

 in regard to the theory of heredity, and I anticipate that the present 

 inquiry will lead to valuable results : that is to say, apart from any 

 other points that may be raised, it will be of equal value either to 

 confirm Cuenot's results or to obtain results different from his, and there 

 is every prospect of one or other of these alternatives being fulfilled. 



The Committee in submitting the above report desire to draw atten- 

 tion to the importance of enabling Mr. Laurie to continue his investiga- 

 tions. The amount granted last year has proved inadequate to meet the 

 necessary expenses, and therefore they now apply to be reappointed with 

 an increased grant.

The Zoologij of the Sandwich Islands. — Eighteenth Report of the Com- 

 mittee, consisting of Br. F. Du Cane Godman (Ghairm^an) Mr 

 David Sharp (Secretary), Professor S. J. HiCKSON, Dr. J» L 

 ScLATER, and Mr. Edgar A. Smith. 



In December 1907 a part of the 'Fauna Hawaiiensis,' by Lord Walsiu<r 

 ham, was published. It includes descriptions and figures of about four 

 hundred new species of Lepidoptera. Another part of the ' Fauna ' is at 

 present in the press. It deals with Coleoptera, the authors beiu"' the 

 Secretary and Mr. Hugh Scott. Dr. R. C. L. Perkins is preparing another 

 part devoted to Coleoptera, and it is hoped that the work will be completed 

 m about a year. 



The Committee ask for reappointment without a grant.
