Questions correctness of two statements in Origin: 1. That fulmar petrels are the most numerous birds in the world;

2. That the increase of one form of thrush in Scotland has been concomitant with the decline of another form.

Wishes CD could publish Origin with footnotes.

Increases in bird populations: starlings are increasing, but AN cannot give reason; mistletoe-thrush increasing but not ousting song-thrush. Doubts trustworthiness of [George?] Edwards, CD’s authority in Origin on this matter [see Origin, 6th ed., p. 59].

AN opposed to bird protection legislation to prohibit egging. Argues egging does not decrease number of birds.

Thanks CD for his opinion on egging. Despite the intensity of the practice sufficient eggs always remain to carry on the breed.
