The memorial, which is accessible, as published in the "Gardeners' Chronicle," November 27th, 1858, page 861, recommended, speaking generally, the consolidation of the National Botanical collections at Kew.
In February, 1900, a Committee was appointed by the Lords Commissioners of the Treasury "to consider the present arrangements under which botanical work is done and collections maintained by the Trustees of the British Museum, and under the First Commissioner of Works at Kew, respectively; and to report what changes (if any) in those arrangements are necessary or desirable in order to avoid duplication of work and collections at the two institutions." The Committee published their report in March, 1901, recommending an arrangement similar to that proposed in 1858.) Down, October 23rd [1858].
The names which you give as supporting your memorial make me quite distrust my own judgment; but, as I must say yea or nay, I am forced to say that I doubt the wisdom of the movement, and am not willing at present to sign.

My reasons, perhaps of very little value, are as follows.

The governing classes are thoroughly unscientific, and the men of art and of archaeology have much greater weight with Government than we have.

If we make a move to separate from the British Museum, I cannot but fear that we may go to the dogs.
