Tropics in the South Sea, to examine the Oscillations of the Ba- 

 roinctLT. 15y iMcssis. Laiigsdorf and Horner. P. 450. From 

 these observations made witli great care, it appears that regular 

 oscillations take place in the barometer between the tropics. It is 

 lowest at half past three in the morning, highest at half past nine ; 

 becomes again lowest at lour in the afternoon, and rises again till 

 ten, when it is at its maximum. The difference of elevation 

 amounts to about -06 or '07 inch.

31. Statistical Description of the Salt Lakes of Russia, with a 

 preliminary Discourse on the Commerce of Salt in that Empire. 

 By C. T. Herrmann. P. 593. This is a curious paper. The 

 Russians obtain their salt chiefly from salt lakes in the Steppes and 

 the Crimea, in which the salt crystallizes during the summer 

 montljs. Since the beginning of the last century, Government 

 have had a monopoly of the salt, and have furnished it to the 

 people at a moderate price, from the benevolent design of letting 

 tiie subject obtain this necessary article at the lowest possible price. 

 But the business in the hands of government is attended with con- 

 siderable loss, which is every year increasing. The lake Elton in 

 north latitude 5Ii° near the Wolga, furnishes by far the greatest 

 quantity of salt. But these lakes are mostly situated in deserts, 

 and the expense uf the carriage of the salt is enormous and con- 

 stantly increasing. 



32. On the actual State of Agriculture in Russia. By C. T. 

 Herrmann. P. 6'G"2. Russia is an agricultural country. The 

 nortliern and southern parts are not so well adapted for the purposes 

 of the farmer, as the middle regions ; the first are too cold, the 

 second consist of the Steppes, which are uninhabitable on account 

 of the want of wood and water. The grain chiefly cultivated con- 

 sists of rye, wheat, barley, and oats ; besides flax and hemp, which 

 are very much attended to. The average return is five times the 

 quantity of seed sown. The following little table will give some 

 idea of the relative proportion of land cultivated, covered with 

 wood, meadow, waste land, &c. in Russia. 



Suppose the extent of European Russia to be 1, then there are 



Cultivated land 0-15022, or -^ 



Woods and forests 0*42973, or a 



Meadows 0-03043, or -^ 



Courts and gardens 000525, or -^
