The specimens are mostly mere bits, pasted down in a huge folio volume. I suspect this was done by Fraser, and the labels have sometimes been exchanged, so that it requires no little patience. Some of the things I most wished to see are not in the collection, and there are several in the collection which are not mentioned in the “Flora.” You would laugh to see what some of the things are that have puzzled us: thus, for instance, his “Cucubalus polypetalus” is Saponaria officinalis! His “Dianthus Carolinianus” is Frasera! in fruit. I will soon send you my notes on the collection, or a copy of them. Bentham looked over the Leguminosæ, Labiatæ, etc., with me. I have had two sittings at Pursh, but have not yet finished; I hope another day will do it, but am not certain. I shall still require about three days more at the British Museum, two at the Linnæan Society, and one at Lindley’s. An evening or two at Bentham’s will suffice to certify his Labiatæ, Scrophularinæ, etc. I must also have a day with Brown, if I can get it at his own house. I hope very nearly to finish this next week, if life and health are continued.... February 12, 1839.--I am fearful even another day will not see the end of Lambert’s collection, and I suspect a week is none too little for the British Museum. Lady Charlotte Bury came into Lambert’s and had a long chat with him; such a pair of originals! She is to dine with Lambert on Sunday, but stipulated early, as she always made it a point to read prayers to her servants on Sunday evening!
