plain unfashionable people in the afternoon. These Whitfieldians are, one would think, farther separated from the Established Church than Wesleyans (which was certainly not the case in Whitfield’s time, who refused to take any steps to establish a sect apart from the Church of England); for in the Wesleyan chapel I attended the liturgy was read, but here we had none of it. Only last summer I read a biography of Whitfield with much attention; and it was very interesting to worship in this chapel of his. It recalls more interesting associations than Westminster Abbey or any vast and splendid cathedral. But I must bid you good-night, purposing to rise early and have an hour or so before the pressing business of the day is commenced to write another sheet to you and our good Dr. Torrey, to whom I have so much to say, if I could ever find time for it. Friday.--I have been to-day at the British Museum, studying from the specimens of Plukenet, Catesby, Miller, etc., etc., the authority for old Linnæan species in Ilex, Prinos, Eupatorium, etc. It is slow and tedious work, and I shall not have time to do so much of it as I could wish. Brown told me to-day about Petalanthera. It is Cevallis, Lagasca, Hortus Matritensis, and very probably his species, even C. sinuata. It came from New Spain. You will see Lindley is all astray about the genus, and no one knows its affinities even, but Brown. Lagasca himself refers it to Boragineæ. It is true Loaseæ. I was this evening at Bentham’s, and found he had a specimen of C. sinuata from Hooker, collected by Brydges in Mexico, I think. I have asked Brown to give us some notes on the subject, a generic character, etc., that we may publish a little from his own pen. I am to spend a day with him next week, and I will try to get something out of him. He hinted to me some days ago that he knew something about Cyrilla, but I could not get it out of him. I’ll try again. He tells me he has a character to distinguish true Rhexia, which has escaped Don, De Candolle, etc. We must find it out. Bentham has given me his “Scrophulariæ Indicæ,” and the three last parts of his “Labiatæ;” I have bought the rest (£1 2s. 6d.), and last evening we looked over his North American specimens, and the notes in his copy. He gave me also, the other day, the only published part of the “Plantæ Hugelianæ” and a few other pamphlets. He is a liberal soul.
