174 FIRST JOURNEY IN EUROPE. £1839, 
to go to Jussieu to-morrow, but Webb has made an 
appointment with me to see Dr. Montagne (muscolo- 
gist, ete.) and his microscope, which is one of the 
latest and best of Chevalier, and will enable me to 
decide if I may venture upon one for Sullivant. 
On Saturday Decaisne told me, almost by acci- 
dent, that he was to do the Asclepiadee for De Can- 
dolle’s “* Prodromus,” at the same time showing me a 
paper of his on the family that I was unacquainted 
with, much to his surprise, but he at once gave me a 
copy. You must know, that although I knew no- 
thing scarcely of this family when I left you, and now 
know little as to general structure, yet I pride myself 
a little on my researches in extricating the synonymy 
of the species in London, in Herbarium Linneus, 
Hort. Clift., Herbarium Gronovius, Banks, Walter 
and Pursh, and here of Michaux. Accordingly on 
Monday (yesterday) Decaisne and myself had a regu- 
lar examination of all the species we could find here, 
and I furnished him with all my notes upon the 
synonymy, and left with him those I had with me 
from your herbarium, to be returned to London in 
September next. Decaisne has been with me also all 
this evening. 
I find that very many of the pamphlets we have 
sent from time to time have miscarried, particularly 
the copies of my ‘“ Ceratophyllacex,” sent by Castil- 
neaux, and, what is mortifying, Guillemin and Jus- 
sieu received copies, but Brongniart and Decaisne 
none. I have just sent my only remaining copy 
here (for you sent me none) to Brongniart,! with 
an explanation. 
1 Adolphe Theodore Brongniart, 1801-1876; distinguished French 
botanist, more especially in fossil botany; professor of botany at the 
Jardin des Plantes.
