‘¢ O Linneus! the world in its successive revolutions eve- 
ry where can offer the ruins of cities, temples, pyramids, with 
those of prostrated columns, gorgeous palaces, and mausolea. 
But the sight of thy gardens is not done away—they are in- 
cessantly renewed with a greater luxuriance. May thy gen- 
ius preside over us, and there always will be a bountiful soil 
for a plant, a fertile country for a nation, and a cultivated 
ground, with a hut for the poor.” 
N. B. A general meeting of the New-York Linnzan 
Branch will take place during the month of November next, 
of which due notification shall be given to distant or resident 
honorary and corresponding members. mmunications 
may be directed to Samuel L..Mitchill, honorary president, 
or to Felix Pascalis, president, or to Elizur Mead, secretary.

3. On the cutting of cast tron by soft iron.— BENNINGTON 
Iron Works, Sept. 1, 1826.—Having recently been a little 
' more at leisure, I have repeated the experiments me ntioned in 
my letter of the 24th January last,* of cutting iron and stee 
by means of a revolving dix of plate iron, and am now con- 
vinced that the difference there noticed in the effect of the 
dix, was owing to the different degress of thickness of the 
substances subjected to trial; and that cast iron is as easily 
cut as either wrought iron or steel, if the plate be thin enough 
to be rapidly heated to ignition in the immediate line of con- 
tact with the disk. Isaac DooLiTTLe. 
4. Correction by Gen. Martin Firtp—Extract of a let- 
-ter addressed to the Editor, and dated Be_Lows Faults, 
une 5, 1826.—In the Journal of Science, &c. Vol. 6, p- 
219, and Vol. 9, p. 55, it is erroneously stated, that Pinite, 
and Rubelite are found at Bellows Falls, Vermont. These 
errors have found their way into other publications ; and the 
applications, from distant correspondents, for those minerals, 
have become very frequent. 
The mineral, which occurs abundantly in the rocks about 
the falls, and particularly on the rocky island above the 
= and on Fall Mountain, is unquestionably Fibrolite, 
which has been strangely mistaken for Pinite.
