carefully watched and encouraged by the professors. The 
pupils in this remarkable session evinced the greatest do-

12. Merrorciocy. Limiis of heat and cold.—lIn uniting 
and comparing a great number of observations made with 
the thermometer, M. Araco has deduced the following con- 
sequences: Ist. In no place on the land, andin no situation, 
will a thermometer elevated two or three metres (from 6 to 
10 feet) above the surface, and sheltered from all reverbera- 
tion rise to the 37th degree of Reaumur or 46th degree of 
the centigrade scale (=115? Farenheit): 2d. In the open 
sea, in whatever place and season, the temperature of the air 
never surpasses 24° Reaumur (=86° Far.) : 3d. The great- 
est degree of cold observed on our globe, with a thermome- 
ter suspended inthe air is—40° Reaumur(=—58° Far.): 4th. 
The water of the sea in no latitude or season, acquires a tem- 
perature superior to 24° Reaumur, or 86° Far.—Idem. 
13. Swepen.—Agreeably to a printed report made to the 
* Society for the propagation of mutual Instruction,” in Stock- 
holm at the general meeting held the 19th of May, 1824, it ap- 
pears that in the twelve episcopal districts of Sweden there are 
60 schools on the new system, and that the number ofpupils was 
continually increasing. ‘The pamphlet contains a statement of 
the receipts and expenses of the society, a list of the 86 
members who composed it, and a discourse of M. Fryxell, 
Recorder, on the utility of the new method.—WM. J. J.

14. Tue American JougNAL OF SCIENCE AND ARTS con- 
ducted by B. Siuuman, M. D. &c.—The February number 
of this journal is thus noticed in the Revue Encyclopédique 
for May 1825. 
“This number of an excellent journal from which we 
have often entertained our readers, is very rich in articles of 
geology, mineralogy, and natural history. The mathematics 
also occupy a remarkable portion of it.” A brief analysis is 
then given of the most important articles in the number un- 
der review, and the writer concludes with the following ob- 
servations :—‘* We see that the journal of M. Silliman is 
among the number of those which are read with pleasure 
and curiosity, as soon as they appear, and which, as a com- 
ponent part of our libraries will be at all times consulted, 
and will furnish useful materials to philosophers of the pre- 
ent and future generations.” -
