Summary
Answers to CD’s queries will take time. CD may not be aware of the influence of accommodation on the diameter of the pupil of the eye. Parrots, for example, contract or dilate the pupil independently of amount of light [see Expression, p. 304]. Sends his book on the subject [On the anomalies of accommodation and refraction of the eye (1864)].
