Has just returned from collecting in Central America and is planning to go to the Galapagos to gather specimens in all branches of natural history.
Notes on sexual differences within certain species of birds.
Shot a sandpiper in Norway, the hind toe of which was clasped by a freshwater bivalve.
Sends replies to CD’s queries about sex ratios in humming-birds.
At the suggestion of J. D. Hooker CD offers his opinion on the value of a proposed collection to be made at the Galápagos. The display would not be attractive or appealing to amateurs in natural history, but the scientific value of good collections of every species would be very great if those of each island are rigorously kept separate.
Encloses some queries.
Would also like information about proportion of male to female humming-birds.
Reference to OS’s paper in Ibis, vol. 2.
CD thanks OS for answering his questions and especially for giving the case of the sandpiper; "such little facts are my delight". [See 6253.]
