To William Ogle 22 September 1875
Summary
Asks whether the twins WO reported to CD [see 5470] were named Macrae. F. Galton has told him of a similar case with twins so named who inherited crooked little fingers from the maternal side [see Variation, 2d ed., 2: 240]. [The twins referred to by WO were actually his sisters, see 10170.]

From William Ogle [23–4 September 1875]
Summary
Asks whether CD has observed that bees limit their visits to a single kind of flower on each journey from the hive, as Aristotle has said they do. What advantage would such a limitation be to the insects?

To William Ogle 25 September 1875
Summary
From Galton’s "twin study" he suspects that some progenitor of WO’s had the peculiarities in question.
Has collected cases of signs of assent for a revised edition of Expression.
Suggests bees visit same species because they know how far to insert proboscis and thus save time.
