extra mortality, which might produce most important results. 

 Many of the streets being extremely long, and containing houses, 

 even in the same ward, differing very greatly in sanitary condition, 

 the number of the house ought in every case to be recorded. As 

 in England, no interment ought to be allowed, without the pro- 

 duction of a duly authorized medical certificate, assigning both 

 the proximate and the remote cause of death, both of which should 

 be recorded. 



The only items tabulated in the City Clerk's register are the 

 numhers in the columns for males and females, and the totals for 

 each week. There are two columns for disease, simply divided 

 between 'epidemic' and 'others;' but the epidemic of cholera, 

 which caused this return to be instituted, (on July 16, 1854,) 

 having terminated in November, no returns have been entered 

 under the disease columns since that date. The columns for 

 ' children ' include all deaths under twelve years of age. 



The returns for 1854 are of course incomplete. There is an 

 entry of 274 deaths from cholera, from June 28 to July 11 ; and 

 of the total deaths registered from cholera being 1067, principally 

 in July. The greatest mortality was in the week ending July 

 23rd, viz.: 281 ; the least, Nov. 25, viz. : 33. The totals are as 

 follows :

The cemetery tables enable us to present the complete returns 

 for twelve years, from Jan. 1, 1855, to Dec. 31, 1866, inclusive; 

 and to divide them between ' children' and adults. 



The population for each year has been calculated, as exactly as 

 possible, not by adding and subtracting a fixed quantity, as in 

 tables 4 and 5, but according to the average rate of increase, which 

 is found to be very nearly '4 • 7 per cent. ; (that of all England being 

 somewhat under 2 p. c.) Of course a considerable part of this large 

 increase is due to immigration, and is a fluctuating element. This
