In the above table it will be seen that Bronchitis was more pre- 

 valent in 1867 than in 1S66, and that there was a large mortality in 

 1 868, This diflerence is owing to imperfect registration. Croup, a 

 more common disease, was more frequent in 1866 than in 1867, and 

 again, in 1S68. Diphtheria was very prevalent in 1866, the mortality 

 much less in 1867, and greater in 1868. Of Laryngitis, no deaths were 

 reported in 1866, 10 in the last six months of 1867, and 23 in 1868. In 

 Pleurisy, there was not much difference. The cases of Pneumonia for 

 1 866, I am satisfied are too low, and that not all the deaths were 

 reported, as there are only three less than in 1867, when the tempera- 

 ture was more equable and the extremes were not so marked as in 1 866, 

 or in 1868. The mortality by this disease in 1S68 was very great in 

 the months of January, February, March, and December, when the 

 weather was extremely cold. A diminution occurred in April and 

 May, when the weather was mild, with an inci'ease in June, when it 

 was again comparatively lower. It was also in January and Feb- 

 ruary that most died of Small Pox, owing to its being complicated 

 with Pneumonia, which is a common occurrence in the latter stages 

 of the disease. In Congestion of the Lungs, the same discrepencies 

 occur, — as, for the first three months, more deaths must have taken 

 place in 1866 than in 1867, owing to the changes of temperature, as 

 corroborated by the observations of 1868. Consumption, the most 

 common and flital of all diseases, is probably more correctly reported 

 than any other. It being a hereditary and protracted disease, the 

 effect of the changes of temperature is not as marked as in the 

 acute pulmonary diseases, other causes tending to its fatal termina- 

 tion, such as occupation, confinement to a vitiated atmosphere, and 

 depressing mental influences. It will be obsei-ved that more deaths
