146 FIRST JOURNEY IN EUROPE. _ [1839, 
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 com- 
menced 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 Mu- 
seum, studying from the specimens of Plukenet, 
Catesby, Miller, ete., etc., the authority for old Lin- 
nan species in Ilex, Prinos, Eupatorium, ete. 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, Lagasea, Hortus 
Matritensis, and very probably his species, even C. 
sinuata. It came from New Spain. You will see Lind- 
ley is all astray about the genus, and no one knows its 
affinities even, but Brown. Lagasca himself refers it 
to Boraginer. It is true Loasew, I was this even- 
ing 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, ete., that we may 
publish a little from his own pen. Iam to spend a 
day with him next week, and I will try to get some- 
thing 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, ete. We must find it 
out. Bentham has given me his ‘ Scrophularize Indi- 
ce,” and the three last parts of his “ Labiate;” 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
