 chand,* (PoggendorfTs Ann, der Phys. u. Chimie, Ixxvi, 462, 1849.) 



A quantity of water from the Dead Sea was brought by Kunovvski 

 to Berlin, which he obtained at the north end not far from the mouth 

 of the Jordan. Its specific gravity at 19° C, was 1*18415; at 13°, 

 1*1859. The analyses afforded

We had 



intended to have given extracts of the proceedings of the recent Session 

 at Cambridge in this number of the Journal. But as a pamphlet is now 

 in course of publication, containing abstracts of the reports corrected 

 throughout by the authors, we defer it for the present. 



The proceedings were published at length in the Boston Evening 

 Traveller, from whose office the pamphlet will soon be issued, and 

 whence copies may be procured. We may add a word in behalf of 

 this daily paper, published at Boston, as we have long appreciated its 

 excellence. The various scientific and literary addresses and lectures 

 of Boston and its vicinity are reported by it in full, and by stenograph- 

 ers that rarely miss a word that falls from the speaker's mouth. We 

 are indebted to the editors in this way for the publication of Agassiz's 

 lectures on Embryology, which we have been assured by those who 

 know, are given with remarkable accuracy. The Lowell Lectures of 

 Boston, by men of the hightest standing in their departments, may, 

 through this paper, be enjoyed in distant portions of our country. We 

 may hope therefore that the Boston Evening Traveller will widely travel, 

 for it is one of the most important means in our country of dissemi- 

 nating scientific and literary information. — Eds.
