THE president's ADDRESS. 215 



estimate enables us also to throw some little light upon the 

 interesting question, what has become of the sons and daughters 

 of Cornwall who have left their native county. 



At the census of 1861 there were Cornishmen living out of 

 Cornwall in the United Kingdom amounting to 21,461. If we 

 take the ordinary rate of mortality in the United Kingdom, this 

 number would be reduced by 1871 to 17,138. 



On the other hand there were living in Cornwall in 1861 

 non-Cornish born persons — 29,678, and these with the same 

 calculation, would be reduced to 24,249. 



In point of fact we find that at the end of the decen- 

 nium, Cornishmen living in the United Kingdom out of Cornwall 

 were 35,628, and non- Cornishmen living in Cornwall were 

 30,767. 



It appears, therefore, that during the decennium at least 

 6,518 non-Cornishmen must have come into the county, and 

 18,490 Cornishmen must have gone out of the county to live in 

 the United Kingdom. The Cornishmen who have gone out of 

 the county in that decennium amount therefore altogether to 

 60,395,* and as we have ascertained that 18,490 have left the 

 county for the United"Kingdom, it follows that 41,905 have left 

 the county for the Colonies and Foreign countries over sea. 

 Applying similar methods of calculation we find :

Yet one more inquiry may be of interest. I have not said 

 anything hitherto in this summary of the proportion of the sexes. 

 But the figures of the census show the males and females in the 

 county at each decennium, and it will be observed how 

 remarkably the proportion has changed during the century. 



*That is 53,877 being the loss of population already quoted, plus 6518, 

 counterbalancing the influx of non-Cornisbmen.
