HWB’s concern over CD’s poor health.
Gives accounts of reviews of his book in the Times and in the Revue des Deux-Mondes by E.-D. Forgues ["Un naturaliste sous l’équateur", Rev. Deux-Mondes 46 (1863): 703–37].
Thanks CD for the A. Gray review of his paper [see 4022].
Reports his current work is a monograph on Mantidae.
