ed a little over the specimen
of M. Andium "hesitating" between the two groups. (155/4. In speaking of
the characters of Mastodon Andium, Falconer refers to a former paper
by himself ("Quart. Journ. Geol. Soc." Volume XIII. 1857, page 313),
in which he called attention "to the exceptional character of
certain specimens of M. Andium, as if hesitating between [the groups]
Tetralophodon and Trilophodon" (ibid., page 100).) I have been assured
by Mr. Wallace that abundant Mastodon remains have been found at Timor,
and that is rather close to Australia. I rejoice that you have smashed
that case. (155/5. In the paper in the "Nat. Hist. Review" (loc. cit.)
Falconer writes: "It seems more probable that some unintentional error
has got mixed up with the history of this remarkable fossil; and until
further confirmatory evidence is adduced, of an unimpeachable character,
faith cannot be reposed in the reality of the asserted Australian
Mastodon" (page 101).) It is indeed a grand paper. I will say nothing
more about your allusions to me, except that they have pleased me quite
as much in print as in MS. You must have worked very hard; the labour
must have been extreme, but I do hope that you will have health and
strength to go on. You would laugh if you could see how indignant all
Owen's mean conduct about E. Columbi made me. (155/6. See Letter 157.) I
did not get to sleep till past 3 o'clock. How well you lash him, firmly
and severely, with unruffled temper, as if you were performing a simple
duty. The case is come to such a pass, that I think every man of science
is bound to show his feelings by some overt act, and I shall watch for a
fitting opportunity.

P.S.--I have kept back for a day the enclosed owing to the arrival of
your most interesting letter. I knew it was a mere chance whether you
could inform me on the points required; but no one other person has so
often responded to my miscellaneous queries. I believe I have now in my
greenhouse L. trigynum (155/7. Linum trigynum.), which came up from seed
purchased as L. flavum, from which it is wholly different in foliage. I
have just sent in a paper on Dimorphism of Linum to the Linnean Society
(155/8. "On the Existence of the Forms, and on their reciprocal Sexual
Relation, in several species of the genus Linum.--"Journ. Linn. Soc."
Volume VII., page 69, 1864.), and so I do not doubt your memory is right
about L. trigynum: the functional difference in the two forms of Linum
is r
