reference to the relationship of each plant as regards the pro¬ 
perties, &c., except that the species of a genus are always 
kept together. The stamens and pistil are the reproductive 
organs, and upon the number, connexion, and situation of 
these the svstem is founded. It consists of 23 classes of 
plants, which have either stamens or a pistil, and a 24th class, 
the plants of which, such as the ferns and mosses, have no 
true flowers. The terms are of Greek derivation, and the 
words andria and gynia are used metaphorically for stamen and 
pistil. The first eleven classes depend upon a definite number 
of distinct stamens; the 12th and 13th upon the number 
and situation of the stamens; the 14th and loth on the 
length of the stamens ; the l6ih, 17th, 18th, and 19 th, by the 
connexion of their filaments and anthers; the 20th, on the 
connexion of the stamen to the style; the 21st, 22d, and 
23d, when the stamens and pistil are not united ; and the 
24th embraces plants without true flowers. 
These classes are again subdivided into orders, the charac¬ 
ters of which are derived chiefly from the pistil. But for 
an arrangement of these classes and orders, I must refer 
the reader to a very clear and perfect synopsis, given in 
‘ Babington’s Manual of British Botany.’

PUNCTURE OF THE COLON BY A PIN CAUSING 
THE DEATH OF A HORSE. 
By G. Fleming, V.S., Military Train. 
On the evening of the 27th Jan. my farrier-major reported 
one of the troop horses as having been attacked by colic 
during my absence from camp, a few minutes previously, but 
that having given him the usual medicines for that affection 
he was now well. 
Happening to go round the stables during the evening 
stable-hour, I saw the horse. He was a fine healthy animal, 
in tolerably good condition, and nothing appeared to be the 
matter with him then, as he was feeding heartily; and when 
the men left the stables for the night he was standing still 
and quiet, eating his hay. 
About half-past four the next morning, I was hastily sum¬ 
moned to see him again, as he had been found by the stable 
picket, lying behind the stable door.
