We are indebted to Mr. Bushnell for a beautiful specimen 

 of Mesotype, which he discovered also at Washington. It is 

 attached to a fragment of gneissoid hornblende, in which rock 

 it appears to occur in veins. It consists of fibrous crystals 

 about an inch in length, which are arranged in a stellular 

 form, the centre of the aggregation being sufficiently compact 

 to yield a splintery fracture. Its color is white, tinged oc- 

 casionally with blue. It scratches calc. spar. Before the 

 blowpipe, it immediately curls up, becomes opaque and vitri- 

 fies without intumescence : with borax, it, with difficulty, af- 

 fords a transparent glass. Attached to the same specimen, 

 and intermingled with the mesotype, I noticed several little 

 masses of transparent, lamellar Stilbite. I am unable to give 

 any information, at present, respecting the quantity in which 

 this mineral exists, but the specimen before me seems to pro- 

 mise, that it will be found to be abundant. 



I have much satisfaction in being able to indicate another 

 occurrence of tabular spar in our country. Mr. Oliver P. 

 Hubbard, a student here, has brought me a very beautiful 

 specimen of this mineral, which he discovered at Boonville, 

 Oneida county, N. Y. It precisely resembles the same 

 mineral found at Willsborough, and with it, is associated, in 

 place of the colophonite, which there accompanies it, a green 

 granular Pyroxene, which, for transparency and richness of 

 color, surpasses every thing of a similar nature hitherto known 

 in this country. The contrast afforded by the delicate white- 

 ness of the tabular spar and quartz, with which, it is mingled, 

 and the fine green of the coccolite, renders it, if possible, more 

 beautiful, than the Willsborough specimens. At any rate, 

 the difference of appearance in the accompanying minerals 

 of these places, will contribute, mutually, to enhance the in- 

 terest of their specimens. Mr. Hubbard informs me, that it 

 promises to be very abundant, although as yet he has not 

 noticed it, in place ; — the specimens he obtained, were from 

 large boulders, which had been dug up, in effecting some im- 

 provements upon the public common in that place. — Yale

5. New Edition of Cleaveland's Mineralogy.— We under- 

 stand that Professor Cleaveland is preparing for the press, a 

 new edition of his treatise on Mineralogy. We are informed 

 that it will be considerably enlarged, and that it will give, as 

 \far as possible, a view of the state of the science, at the time 

 )f its publication.
