25,000 are not domiciled. The average nuniber of births annually 

 is 21,000, and of these, the proportion of males to females is as 

 25 to 24. The annual consumption of bread is ll.j, 880,000 

 kilogrammes; of oxen 70,000; of heifers 9,000; of calves 

 78,000; of sheep 34,000; of swine 72,000; of eggs 74,000,000; 

 of pigeons 900,000 ; of fowls 1,200,000 ; of wine 870,000 hec- 

 tolitres. 



Sueden. By the census taken in 1819, the population of the 

 kingdom appears to be 2,543,412. The births in that year were 

 2329, and the deaths 3238— difference 909. Nearly a half of 

 the children are born out of marriage. One out of three chil- 

 dren have invariably died. Marriages 504, and divorces 24. 



Prussia. From reports drawn up in 1819, it appears that all 

 the States, exclusive of Neiifchatel, comprehend 5014 square 

 geographical leagues (15 to a degree of the ecjuator, equal to 25 

 French leagues) or 2,202,54 1 acres Rhenish measure, with 

 10,800,112 inhabitants, including tlie military. All the great 

 bodies of water occupy about 2,202,541 acre;; — about a 49th 

 part of the whole surface. It results from a census by the police, 

 that at the end of 1818 the population had been augmented 

 75,000, by foreigners having settled there : in Berlin alone were 

 enumerated 1042 males and 1728 females that had arrived there 

 in 181') to seek employment as domestics. 



The whole population of Greenland, according to the last Re- 

 port of the Missionary Board, consists of 3586 individuals, spread 

 through 17 colonies on the western coast. The interior is not 

 habitable, owing to accumulations of ice. The population has 

 increased 714 since the year 1789. 



The entire population of the Tyrol and the Voralberg in 1819 

 consisted of 355,030 males and 377,052 females. Total 73'^,082. 

 In the Voralberg alone the individuals were 81,966. The in- 

 crease since 1808 has been very considerable. 



RKiMEDY FOR MILDEW ON WHE.^T. 



Dr. Cartwright, to whom the agriculturists of the kingdom lie 

 under great obligations for numerous improvements, has disco- 

 vered that a solution of common salt, spriidded on corn infected 

 with mildew, completely removes the disease. In the year 1818, 

 he was engaged in a series of experiments to ascertain the mini- 

 mum of salt that would be re(]uired to destroy vegetation in cer- 

 tain weeds, as coltsfoot, bindweed, the common thistle, &c. The 

 salt it was found had very little effect on weeds or other vegeta- 

 bles, when they had arrived at that stage in which they cease to 

 be succulent and are becoming hbrous ; but as soon as the rain 

 washed the salt down to their roots, if in sufficient (piantity, they 

 languished and died. Happening to ha^e some wheat at the time 

 that was mildewed, the Doctor reasoned thus: The mildew is
