The following table, exhibiting the principal causes of death, during the last six years, and the birthplaces and parentage of those who died in 1854, presents the record of mortality in an interesting light. In all estimates connected with the mortuary statistics of Boston, a city that contains a foreign-born population nearly equal to that of the native-born, the consideration of the fact of parentage should not be omitted. The localities that the former occupy, together with their habits, &c., justify the exhibition in this distinct form :

It will be seen by the foregoing statement, that from only seven diseases-viz. Apoplexy, Disease of the Brain, Erysipelas, Old Age, Palsy, Thrush, and Typhoid Fever, was the mortality among native-born persons greater than among foreigners and their children, united. The great disparity between the deaths of foreigners and Americans from Disease of Bowels, Congestion of Brain, Cholera, Consumption, Convulsions, Croup, Debility, Dropsy in the Head, Infantile Diseases, Dysentery, Hooping Cough, Inflammation of the Lungs, Marasmus, Measles, Teething, and Puerperal diseases, is most striking and suggestive.

As usual, Consumption appears as the prime destroyer, -numbering 752 as its victims,-an increase of 19 over the number of any previous year, being nearly 17 per cent., or one-sixth of the whole number of deaths. The deaths of Irish males and females, and American females, are very nearly equal; while those of each class are very nearly double those of American males. Of the foreign-born that died of Consumption, 400 were Irish (including 30 children of Irish parents), 14 English, 10 Germans, 6 Scotch, and 31 were born in the British Provinces.

Of Cholera, 261 cases are reported. The first death in Boston from this malady occurred on the 10th of June, in Fleet street. The victim was an Irish laborer. By referring to the foregoing table, it will be seen that only 38 of those who died of Cholera were born here, not including 36 children of foreign parents, being about 1 to 6, compared with foreigners and their children. An examination of the localities to which the disease was mostly confined, will give to this great disparity a striking significance.

There were but few cases in which the predisposing cause could not be easily traced to filthy and ill-venti
