relatives. Next to this is that which con- 
tains the’coninion people, then that whicli 
comprehends those of the same tribe, 
afterwards ‘that which’ cotitains ‘the citi- 
zens ; “and then! two other circles: follow, 
one:being the:circle of those that dwell in 
the vicinity of the city; and the other of 
those, of, the, same province. But the 
ontermost .and greatest circle, and which 
comprehends, all. the other circles, is that 
of the whole human race.” 
On; comparing these two extracts 
with each ‘other, it appears that in 
Hierocles the circles are scientifically 
detailed;: but that in Pope they are 
synoptically enumerated. Pope, too, 
has added another circle to that which 
is the outermost with Hierocles, viz. 
the circle which embraces every crea- 
ture of every kind. But as Hierocles 
in this fragment is only speaking of 
our. duties to kindred, among which 
the whole human race is in a certain 
respect included, he had no occasion 
to introduce another circle, though the 
Platonic doctrine of benevolence is as 
widely extended as that of Pope.

SIR, 
OUR. correspondent N. Justitia, 
in your last Magazine, gave you 
deserved credit, in saying you admit 
fact in preference to falschood, and he 
may add, you give more confidence to 
fact than to hearsay. Relative to the 
use of slaked lime on apple-trees, there 
can be no doubt of its being useful in 
the destruction of all insects, from its 
caustic quality in the immediate use on 
slaking; but it is soon deprived of the 
burning quality. Itis commonly used 
to, prevent the slugs from eating the 
young peas ; while dry and unslacked, 
the shigs crawling on it, their moisture 
causes the burning heat in the slak- 
ing which destroys them. As soon as 
ahy wet falls ‘on the lime, the destruc- 
tive quality is lost, and slugs will crawl 
over it, and destroy the peas. I have 
tried saw-dust, ashes, barley-husk ; 
while dry, the,. pricklincss prevents 
them from crawling up; but as soon as 
wet the effectis lost ;and the only way 
to get vid of them is by keeping ducks, 
who do noanjary to vegetables, but in 
the fruit season’ f) remove them from

all vegetables receive from the vapour 
and air, so essentially necessary for the 
health of trees. Your correspondent 
concludes that the good effect of the 
lime is proved by the fruit being much 
larger: that might arise from a different 
cause,—the year before might. have 
been superabundant; when that is the 
case, the fruit runs smaller than when 
there is a less quantity. It is a com- 
mon practice with gardeners to pick 
some of the fruit off the trees, that the 
remainder may be finer. 
1 am very doubtful if N. Justitia’s 
conclusion is founded on fact; the be- 
nefit the tree had received, by the 
proof of the fruit being larger, might 
arise from the above cause.

A PLAN suggested ultimately to ex- 
terminate the NATURAL SMALL-POx ; 
and to establish, by the TEST of EX- 
PERIENCE, the EFFICACY of COW-POCK, 
in the PREVENTION generally of that 
DISEASE; by J: VALE ASBURY, EsQ. 
MEMBER of the ROYAL COLLEGE of 
SURGEONS, and LICENTIATE of the 
SOCIETY of APOTHECARIES 7 LONDON. 
HAT the introduction of cow- 
pock as a substitute for the small- 
pox, should occasion contention, is not 
singular, when we consider the diver- 
sity of opinion generally inherent in 
the mind of man ; but, that the practice 
of vaccination should meet with so much 
opposition after twenty-four years’ ex- 
perience in England, and successfully 
in thousands of cases, is matter of asto- 
nishment, and can only be accounted 
for on the rank soil of prejudice. The 
late Bishop of Landaff, in the Anec- 
dotes of his Life, observes, that “our 
opinions on many important subjects 
are founded as much on prejudice as 
on reason;” the pretended ground of 
objection maintained. by the anti-vac- 
cinists furnishes us with ample proof of — 
the accuracy of this observation, It 
may be asked, where is even the atom 
of reason manifest in, preferring the 
malign disease, that horrible pestilence, 
which, if it do not destroy life, leaves its 
victim blind, beset with running sores, 
and thus becoming a loathsome. object 
of compassion, to that benign affection 
the cow-pock, which neither engenders 
disease nor produces deformity? 
The beneficial influence which every 
being may deriye from yaccine inocu- 
lation, will be best illustrated by taking 
askeich of the nature, and great fata-
