Citizen Coulomb, fome time fince, 
caufed feveral large poplars to be cut 
down on his eftate. lt was in the {pring 
feafon, and the fap had begun to mount 
into the branches, which were covered 
with new leaves. As he was infpeét- 
img the workmen, he noticed that one 
of the trees, on being cut nearly through 
to the centre, emitted a found fimilar to 
that produced by air bubbling from the 
furface of water. He perceived that this 
poife, as Well as the difcharge of a limpid 
and taftelefs liquid, did not take place 
till the trees were neatly cut through 
to the centre, ‘This led him to furmife, © 
that the fap in large trees was only 
imparted to the branches by the me- 
dullary canal in the centre, with which 
rhe branches have a direét communica- 
tion. To afcertain this point, he caufed 
feveral large poplars to be pierced with 
a borer, when it appeared, that, within a 
certain diftance of the centre, the infiru- 
ment remained nearly dry ; but no fooner 
did it penetrate to the middle, than a 
watery fubftance was emitted in great 
abundance, accompanied with the bub- 
bling nvife before mentioned. This effect 
was regularly produced on every repeated 
experiment during the fummer, the found, 
as well as the liquid emitred, bearing a 
.due proportion to the precife degree of 
heat, and confequent tranfpiration of 
the foliage. At might, and during cold, 
damp days, very gtle effect was difcesned.

From thefe experiments it fhould feem’ 
that the only circulation of ‘the fap in 
trees is effeéted by the parts which border 
on this centrical medullary canal, by means 
cof the infinite number of horizontal radi, 
at the extremities of ‘which ‘the buds 
are formed, which eftablifh'a fucceffive 
communication with the centrieal canal. 
This communication, of courfe, augmerts 
in exaét proportion to the growth of the 
bud till it becomes a branch. 
Dr. Reimarus, correfpondent. of the 
Hamburch fociety, having remarked, that 
a few drops of belladonna diffolved in 
water, and applied to the eyes, caufe the 
pupil to dilate in fo extraordinary a 
manner, that the iris is nearly reduced 
to nothing, was led from this circum- 
{tance to fuggeft the propriety of having 
recourfe to this expedient, preparatory te 
the operation of couching the eye for a 
cataract. Ofthis intimation Dr.Grafmeyer, 
who praétifes this operation with grear 
fkill at Hamburgh, has made a very fuc- 
eefsful experiment. The effect produced 
by the folution in queftion on the eye, 
continues about half an hour, affording, 
by the dilatation of the- pupil, an excel- 
fent opportunity of performing the ope- 
ration, without danger of hurting the iris; 
and the palfy, if it may be fo termed, 
which invades the retina, prevents the bane- 
ful confequences which otherwife might 
accrue from too fudden acceffion of light. 
Bothe, of Magdeburg, is engaged upon 
a new critical and exegetical edition of the 
works of Plautus. A f{pecimen, which he 
has already publifhed, of his undertaking, 
proves him completely qualified for the 
tafk, and poffeffed of great critical knuw- 
ledge. 
Gerard Vrolick, profeffor of phyfic and 
botany, at Amfterdam, has publifhed a 
differtation, at Leyden, on the annual de- 
foliation of trees and vegetables ; in which 
hexmaintains, that the leaves of trees have 
a diftis&t vegetable life, chara€terized by 
different periads, though conneéted with . 
the life of the parent tree, and in fome 
meafure dependant thereon. On the an- 
nual return of the period of defoliation, 
the leaves drop off and perifh with age, 
but the life of the ftock fubfifis. He 
Maintains that the dead leaves detach 
themfelves from the branches by the 
fame laws which caufe any mortified part 
of an organized body to feparate itfelf by 
the abforption of the live particles imme- 
diately conne&ting the decayed and healthy 
members. ‘To prove this affertion, he 
cites examples from organized animals, 
which, as well as vegetables, poffefs many 
parts endowed with a diftinét and feparate
