indeed, occupy themselves more with the dis.

with their habits and modes of life, But we

which elves little or no special knowledge of

illustrations of this during the last few years

Quite apart from what: alin be thought of the 
Darwinian “theories, the astonishing influence 
they have had in interesting the public 
scientific matters, and the powerful stimulus they 
have given to research BS observation, will be 
admitted by all, ur thinking, indeed, this 
is one of the strongest ali: of the inherent 
truth of the doctrines in question. If there were 
not a very large infusion of truth in them, they 
E 
would not manifest so much vitality, and act so 
powerfi in i ing the aggregate of our 
‘nowledge on physiological matters. If they 
contained less truth, we might, indeed, hav vid 
endless dah de a but they would be relatively 
barren in 5. 
aiis no wish to dwell on these points, 
our object now is simply to call attention once 
again to the circumstance that there is a depart- 
ment of botanical science which anybody with 
a pair of eyes and average intelligence may 
work at with pleasure to himself, and profit to 
ic importance, but ie reason 
of their direct practical value, The e- 
ration, if not the present, must consciously or 
y modify their ņț ding to

Influenced by these motives we now venture 
n thinking 
over the subject, thought that e movement 
must be due e alternate changes of form, 
now long, now ret in the constituent cells of 
the stamens. In order to verify this M. HECKEL 
ope himself of anzsthetics. He does not say 
sftp is mote he placed 
at you oak the stamen 
to take from them a slice to examine under the 
microscope, you cause contraction ; bt by, so 
to speak, paralysing the cells, a section may be 
taken, and the normal unirritated condition of 
the cells ascertained. So treated, longitudinal 
slices of the irritable part of the stamen (the 
concave inner surface in this instance) are seen, 
according to M. HECKEL, to be arranged in 
arallel rows, and each cell to be longer than it is 
wide, its yellow contents being diffused “aps a

So far M. HECKEL has been alluding to the 
inner concave face of the Berberis stamen, by 
Meigs fi which with a pin, or other convenient 
thing, we ‘may excite the movements already 
alluded t to, and which are excited, as we know, by 
honey.
