tion Argo ; the value of the mass of Uranus, deduced from observations of 

 its satellites, by Dr. Lamont of Munich ; and other short notices. We have 

 notes of observations at the Zoological Society, by Mr. Bennett on the tenta- 

 cula of Physalia pelagica ; by Mr. Gray on the cephalopod inhabiting the 

 argonaut ; by Mr. Bell on the genus Galictis which, with the two species G. 

 vittata and G. allamandi, he characterizes ; and by Mr. Ogilby on the Hylo-

 several papers have been read — Mr. C. C. Babington's on the structure of 

 the Cuscuta europa-a the greater dodder; Mr. Griffiths on the Mosses of 

 Upper Assam, including many not hitherto described ; Mr. Scomburgh's on 

 the Mora excelsa, a lofty and singular tree, native in the forests of British 

 Guiana, affording timber of excellent quality, being close-grained, strong, 

 tough, and durable, and not liable to split; and Mr. Valentine's on the ex- 

 istence of Stomata in Mosses where these organs were generally supposed 

 to be absent until JMr. V. discovered them in the Bryum crudum and the 

 Fumaria hi/gromelricu, in which last they consist of a single cell in the form 

 of a hollow ring. The Theory of Volcanoes, constituted the subject of a 

 paper read at the Royal Institution, by Mr. Brayley, whose object was to 

 explain the theory of volcanic action dependent on that of the secular varia- 

 tion of the isothermal surfaces within the globe, and to offer reasons why 

 the chemical theory of volcanoes originally proposed by Sir Humphrey Davy 

 should not be discarded ;is a mere chemical dream. Mr. Blake's experiments 

 relating to the electrical currents produced during the processes of fermen- 

 tation and vegetation ; Mr. Watkin's letter on the decomposition of water 

 by thermo-electricity ; and Messrs. Dease and Simpson's discovery of the 

 north-west, come under the head of intelligence and miscellanies, which are 

 followed by meteorological observations and a table closing the "June" of 

 this very instructive and philosophical journal.

 Edinburgh, 1838. 



This Journal fiist appeared on the field of literature in 1823 ; and, " from

 human race ; and they have endeavoured to accomplish this end in that 

 spirit of purity and peace which their philosophy so strongly inculcates on 

 those who embrace its tiuths." Fifty-three quarterly numbers, forming ten 

 thick volumes, having been completed, the conductors open a new series of 

 their periodical with No. LIV, and renew their engagements to prosecute 

 the original objects of the journal in the same generous spirit and with una- 

 bating zeal.
