tween sixty and eighty, eleven and two-thirds per cent. ; above the age of 

 eighty, thirteen and a quarter. 



The other term af comparison is procured by taking '-iOOOof the inhabi- 

 tants of the l2fh airondisseinent of Paris, where the workmen belong almosi 

 entirely to laborious trades, and are so poor that at least: three-fourths of 

 them die in the hospital. Among these 2000 individuals. M. Henoiston dt 

 Chateauncuf found, that of persons between the ages of thirty and sixty, 

 seven and a quarter percent die annually; between the ages oi sixty and 

 eighty, twenty-one and nine-tenths; and above eighty, all died within one 

 year, The relative mortality at short intervals of asres will appear from the 

 following table, where the first line indicates the intervals of age, the second 

 the annual per centage of deaths in the richest order of society, and the 

 third the annual per centage in the poor ranks. 

 30 to 40-50—60—70- 80—90. 



Rich, 1.08, 1.17, 1.941, 3.60, 8. 04. 13. 22. 



Poor, 1.57, 2.13, 3.50, 7.50. 14.36. 100.0. 

 It appears from an important document, printed a few months ago, by the 

 Faculty of Advocates of Edinburgh, thai in that body, consisting of in- 

 dividuals who enter in not younger than 21, and on an average at the age 

 of 23 or 24, the expectation of life, or the number of years which they live, 

 one with another, after their admission, is 402-1 lths nearly This calcula- 

 tion is taken from the lives of 210 individuals, the whole of whom entered be- 

 fore the year 1765 ; and since then it is well known that the average dura- 

 tion of life has been considerably improved. Among the 210 individuals, 

 113 survived their entrance (at the age of 24) 40 years or upwards ; of these 

 118, 29 survived between forty and forty-five years; 25 between forty-five 

 and fifty ; 25 between fifty and fifty-five; 17 between fifty-five and sixty ; 13 

 between sixty and sixty-live; 3 between sixty-five and seventy ; and one 

 survived 73 years. 



DOMESTIC ECONOMY. 



Fuel for the purposes of Heating and Cooking.— \n order to ascertain 

 what quantity of ground' will grow a faggot to consist of eighty black 

 Italian or Lombardy poplars, or Huntingdon willows, of three years 1 growth. 

 These we shall suppose to be grown in rows, 2 feet apart, and the plants 

 6 inches distant in the row. At this rate every plant will occupy a square 

 foot, and as there are 43,560 feet in an acre, that space will consequently 

 produce 544 faggots every third year, or every year 181 faggots of three 

 years' growth, which are thirteen more than will be wanted for the purposes 

 of baking and warming throughout the year. Now, these 13 faggots being 

 composed of 1040 shoots, say only 1000, suppose them to be distributed at 

 equal distances throughout the acre, and allowed to attain five years' growth 

 instead of three, this will give 200 trees a year, three-fourths of the length 

 of which will cut up into bundles of billet-wood from 2 inches to 5 inches 

 diameter, for cooking on the open fire ; and the side spray, and the remain- 

 ing third part of the stem may be made into faggots, to make good the re- 

 quisite number for the oven, or to compensate the injury which these 1000 

 larger trees may do to the 30,560 among which they are placed : this calcu- 

 lation we think is sufficient to show thai an acre of wood applied to cottapt - 

 on our construction, and probably even to those on the ordinary plan, will 

 supply fuel for every year. 



On the poisonous Effects of certain spoiled . rftieles «f Food.— (Archive* 

 Generates de Madeline, Fevrier, 1830.J— It is well known thatc?rlain articles 

 of food have been frequently observed on the continent to acquire poisonous 

 qualities of a peculiar kind, and in a way which chemists :uiH physicians 

 have not hitherto been able to explain very satisfactorily. Among Ihcse arti- 

 cles the most frequent are a peculiar kind of sausage, and a particular kind 

 of cheese used in Germany ; but both in France and Germany bacon and 

 ham ha\e been also several times found to acquire poisonous qualities analo- 

 gous to tho^c which characterize the sausage poison and cheese loison. A 

 very elaborate inquiry into an accident supposed to hare arisen from spoiled 

 ham, has just been published by M. Olivier, in the Archives Gem-rales dr 

 .Medecine. His investigations set completely at rest the common notion Ihfl I 

 such accidents arise from the accidental impregnation of the meal with n 

 tallic poisons; but he has not succeeded in discovering the real cause.
