Thanks for his memoir ["On the appendicular skeleton of the Primates"].

Has asked gentlemen who administer chloroform to make observations [on expression?] for CD.

Answers CD’s queries on sexual characters and differences among the Urodela.

Is interested in the relationship of pectoral and pelvic limbs in man and apes and has looked at reptiles and amphibians to find traces of the earlier conditions of the limbs.

Asks whether CD knows any instances of deformities or pathological conditions occurring simultaneously in both sets of limbs.
