mortality of Surrey, that is to say, of the population of Extra-Metro- 

 politan Surrey, which from its large amount will give satisfactory results ; 

 and I further think that we should make the comparative calculations for 

 the same year that the ages were determined, as the only method which 

 can give reliable results. 



" Are there reliable data upon which similar calculations may be made 

 with regard to Beddington parish, as it is of much public importance that 

 a minute calculation should be made to compare the expected with the 

 real results ? 



" I have the honour to be, my dear Sir, 



" Yours very faithfully, 



"ALFRED SMEE.

" MY DEAR SIR, Adequate materials exist in the Census Report for 

 1871, and in the Registrar-General's Annual Report for the same year, to 

 calculate the mortality which might be expected amongst the population 

 of Croydon based on the mortality which occurred amongst the population 

 of Extra-Metropolitan Surrey. 



" I have the pleasure to enclose the result of the calculations, made 

 for every year up to five years of age, for every five years up to twenty-five 

 years of age, and subsequently for every ten years of age ; but as the 

 population of Croydon is included in the population returns of the Census 

 with reference to Extra-Metropolitan Surrey, I have deemed it necessary 

 for the purpose of a rigorous comparison to subtract from the population 

 of Extra-Metropolitan Surrey the numbers of persons living and dying in 

 the district of Croydon, by which it is shown that 56 more deaths at all 

 ages occurred at Croydon in 1871 than might be expected from the 

 mortality of Extra-Metropolitan Surrey. I have also calculated the mean 

 mortality per thousand; the results will be seen in the accompanying 

 tables. 



" It is to be remarked that the mortality of the first years of infancy 

 is greatly in excess at Croydon over that in the Surrey district. 



" I am not aware that any materials exist for estimating the mortality 

 in Beddington parish, as the Census reports do not distinguish the popula- 

 tion of that locality from the population of Extra-Metropolitan Surrey, and 

 the deaths are not given separately by the Registrar-General. 



"It is proper to observe that as the deaths in Croydon town are 

 conjoined with those of surrounding districts, it is probable that, if the 

 returns of its suburban districts were subtracted from the returns under 

 the head of ' Croydon,' so as to reduce the figures to those of the town 

 proper, the deaths in Croydon would appear in still greater excess.
