Birthday congratulations from the Naples Zoological Station. A new physiological department will be constructed. Describes work in progress at the Station.

Sends his paper on teleosteans.

Heard R. Owen read a paper at York [meeting of BAAS]. Owen had views similar to AD’s, but seemed not to be aware of work of others.

Thanks for AD’s letter.

Owen has published a paper on the brain in relation to the mouth ["On the homology of the conario-hypophysial tract", J. Linn. Soc. Lond. (Zool.) 16 (1881–2): 131–49]. CD cannot avoid suspicion that the original idea was borrowed from AD.

F. M. Balfour very ill. His death would be a great loss.
