early suggested by Mr. Ward, and has been tested and confirmed by 
extensive experience ; as appears from the instances related in the text, 
and the testimonials of Loddiges, Hooker, Lindley, Smith, Graham, 
&c. given in the appendix. As we have not sufficient space for the 
details of these experiments, we can only state the general results, 
which are, that plants from South America, Australia, India, &c. 
sed during the voyage to temperatures varying from 20° to 120° Fahr. 
have almost uniformly reached England in a healthy condition, when- 
ever the directions of the inventor have been faithfully attended to: 
viz. when the plants were not over-watered when packed up; the cases 
well closed; the glazed roof protected with strong wire-guard; or 
the panes accidentally broken immediately replaced; and the plants, 
thus protected from the spray of the sea, fully exposed to. the light of 
day. The latter precaution is all-important; for, as Mr. Loddiges re- 
marks, there cannot be a worse method of sending living plants than in 
these same cases placed in the dark. 
Did our limits allow of further extracts from this little treatise, we 
would fain notice the hints which our author throws out for the illustra- 
tion of vegetable physiology and pathology, on the importance of light 
in the animal economy, of pure air in the treatment of diseases and of 
the mode of obtaining it, and, above all, his kind attempts (worthy the 
true lover of Nature) to diffuse the enjoyments which his discovery af- 
fords him among the poorest classes of dark and crowded cities, “ the 
most unfurnished with the means of life,” many of whom, either from 
early associations, or from that love of Nature which exists to a greater 
or less degree in the bosom of us all, are passionately fond of flowers, 
and endeavor to gratify their taste at no small = 
4. Hooker’s London Journal of Botany.—Besides the continuation 
of Mr. J. Smith’s paper on the arrangement and definition of the gen- 
era of Ferns, (which we have previously noticed,) the August number 
of this well-sustained periodical comprises a short article by E. Tuck- 
erman, Jr. on the Empetrum Conradii, Torr., which, having been es- 
tablished by Dr. Klotzsch, of Berlin, as a separate genus under the 
pre-occupied name of Tuckermannia, Mr. Tuckerman has with pecu- 
liar propriety given it the name of Oakesia ; thus paying a deserved 
compliment to Mr. Oakes of Ipswich, Mass., one of the discoverers of 
this interesting plant within the limits of that state, and ‘* whose name 
is inseparably connected with the New England flora.” Dr. Torrey 
was led to suggest the probability of the existence of this plant in New- 
foundland from the enumeration of a second species of Empetrum by 
Pylaie, in his catalogue of the plants collected in that island; and the 
fact has recently been confirmed by Mr. apres who examined a 
Vol. xz111, No, 2.—July-Sept. 1842.
