214 THE president's address. 



being compiled from the returns made by the registrars within 

 the several poor law unions, and as along the boundary of 

 Devonshire, unions now overlap a little on one side and now a 

 little on the other, the identification of the two counties is not 

 exact. But the overlapping portions do very nearly counter- 

 balance one another, and we shall not go far wrong if we take 

 the births and deaths in the registration county as if they 

 applied to the geographical Cornwall. The figures then are : — 

 1851-60— Births .. 122,663 

 Deaths . . 73,367 

 showing an overplus of births of 49,296, and as the actual 

 increase was only 13,832, it is evident that there went out of the 

 county in the course of the 10 years at least 35,464, and if these 

 had remained within it, the total popiilation would have been 

 404,854. 



Following up a similar process for succeeding decennial 

 periods we find : — 



1861-71 1871-81 1881-91 



Overplus of deaths over births .. 46,830 33,903 31,026 

 and as there were fallings off of 

 population in each decennium 



to the extent of 7,047 31,667 8,115 



there must have been an out- 

 going of at least 53,877 65,560 39,140 



This shows a total emigration from 1851-1891 of at least 

 193,641. As it may be assumed that out of this army that has 

 gone forth, those who have died have left at least an equal 

 number of descendants behind them, we can easily understand 

 that Cornish men and women and their children now living out 

 of the county are fit to rank in numbers with those remaining 

 at home. In fact the numbers that have gone out have 

 exceeded those given in these tables, because there has been a 

 small, relatively unimportant, but still measurable, movement of 

 population from without the county into it, and the emigration 

 must be increased by the numbers required to counterbalance 

 this inward movement. 



We are able, by a little further examination, to estimate, 

 at least approximately, what correction should be thus made, 

 and the facts we shall have to consider in arriving at this
