INFLUENCE OF CLIMATE ON THE MOST COMMON 



DISEASES. 



The following tables* show the comparative mortality of certain 

 diseases for the last three years ; and, although the registration 

 of deaths and the nomenclature of the diseases were very imperfect 

 until 1S67, when the present system of registration was inaugurated 

 by the Board of Health, still they are sufHciently accurate to give a 

 very good idea of the relative mortality, as influenced by climate for 

 the different years. This will be better appreciated when I state, that 

 in 1866, 475 deaths were reported from unknown causes, and as near 

 as I am able to ascertain, about 500 deaths occurred of which no 

 record has been kept. In 1S67, 134 deaths were reported from 

 unknown causes, and nearly all in the first six months, and about 100 

 deaths occurred of which no record has been kept. In 1S6S, only 28 

 are reported from unknown causes, and about 34 in which no record 

 could be obtained. In judging of the comparative mortality, the 

 increase in population must be taken into consideration.

* Valuable assistance has been rendered, in the preparation of all the tables, by J. W. Russell, 

 Secretary, and H. P. Wright, Clerk of the Board of Health ; and I am indebted to Mr. J. G. Lang- 

 GUTH for all meteorological observations, not otherwise credited, taken at 117 Randolph Street
