tres des moyens
d'attaque."[204]

Turning to the 'Botanic Garden' itself, I find that this admirable
sentence belongs to M. Deleuze, and not to Dr. Darwin, who, however, has
said what comes to much the same thing,[205] as may be seen p. 227 of
this volume. But the authorship is immaterial; whether the passage was
by Dr. Darwin or M. Deleuze, it was, in all probability, known to
Lamarck before his change of front.

The note on Trapa Natans again[206] suggests itself as the source from
which the passage in the 'Philosophie Zoologique' about the Ranunculus
aquatilis is taken,[207] while one of the most important passages in the
work, a summary, in fact, of the principal means of modification, seems
to be taken, the first half of it from Buffon, and the second from Dr.
Darwin. I have called attention to it on pp. 300, 301.

We may then suppose that Lamarck failed to understand Buffon, and
conceived that he ought either to have gone much farther, or not so far;
not being yet prepared to go the whole length himself, he opposed
mutability till Dr. Darwin's additions to Buffon's ostensible theory
reached him, whereon he at once adopted them, and having received
nothing but a few notes and hints, felt himself at liberty to work the
theory out independently and claim it. In so original a work as the
'_Philosophie Zoologique_' must always be considered, this may be
legitimate, but I find in it, as Isidore Geoffroy seems also to have
found, a little more claim to complete independence than is acceptable
to one who is fresh from Buffon and Dr. Darwin.
