Summary
Agrees Max Müller’s book [see 3752] is interesting but cannot see how it will further his "cause".
A book by J. W. Colenso [The Pentateuch and book of Joshua critically examined, pt 1 (1862)] has just appeared and will "make a noise".
Would like some observations made on Cypripedium.
Will not publish yet on Lythrum as he must make many more crosses; the mid-styled is fertile with half of its own stamens.
Would like to try a few experiments on tendrils.
