78 A Description of a new Mineral Species. 
Phenomenon in vegetable life —Near Quincy, in Middle Florida, 
the following fact has been witnessed by myself, in common with ma- 
ny others: Two Pine trees (Pinus palustris,) of considerable height 
growing near each other, the trunk of one of them, near its upper ex- 
tremity, coming in contact with a limb of the other, they grew toge- 
ther. Subsequently, the former became severed near the earth, by 
burning, apparently. The tree, thus severed and suspended, conti- 
nués to live! deriving its sustenance entirely from the fluids on the 
the other tree—a remarkable parasitic !

Read before the Boston Natural History Society, July 7th, 1833. 
Durine the summer of 1827, Mr. F. Alger and myself made a 
Mineralogical and Geological Survey of the peninsula of Nova Sco- 
tia, an account of which was published in the American Journal of 
Science, Vols. xiv. xv. While on this survey, we collected a great 
number of minerals, principally of the zeolitic family—among which 
we observed several groups of crystals, having the lustre and general 
appearance of analcime, but incompatible with that species, in their 
crystalline form. On our return to Boston, I examined, more partic- 
ularly, the external and chemical characters of this mineral, and 
showed it to my friend Mr. Nuttall, who requested me to let him take 
the specimen with him to London, where he showed it to Mr. Brooke, 
who measured the angles of the crystal with the reflective goniometer, 
and expressed his opinion that it was phosphate of lime. 
On Mr. N’s return to thiscountry, he told me of Mr. Brooke’s de- 
cision. I mentioned to him the manner in which the mineral com- 
ported itself with tests, and before the blow-pipe flame, which prov- 
ed that Mr. Brooke was led i nto error by taking one set of characters 
only. A few crystals were now sent to Dr. Torrey, of New-York, 
by Mr. N. requesting his opinion of them. A short time after which 
Dr. Torrey published a note in the American Journal of Science, sta- 
ting his belief that the mineral was Nepheline. 
While in Paris, I gave a few crystals to Mr. Dufrenoy, of the school 
of mines, requesting him to measure them with the reflective goni- 
ometer, and to give me the result of his examination. I received a 
note, a short time afterwards, giving me some of the angles which he
