For the proportions of the deaths by measles, scarlet fever and small-pox 

 at the different ages, to the whole deaths, for the towns in Scotland, and 

 their striking correspondence with the above, we have to refer to the preceding 

 tables, in which they are exhibited. The following results brought out for 

 other diseases, in a similar manner, show, that were the Scotch registers so 

 improved that we could rely upon their accuracy, there is a great probability 

 that the proportion of deaths at different ages, in a given population, by any 

 particular disease, would be found to be nearly uniform, whatever the total 

 amount might be ; and that when there was a departure from a certain pro- 

 portion at these ages, a local cause might be found to account for it. 



It will be found from the tables showing the average annual amount of 

 deaths by the several diseases, that the proportion of the total deaths by the 

 diseases included under the head of bowel complaints, amounts to 0*167 per 

 cent, of the population in Edinburgh ; to 017 1 per cent, of the population in 

 Perth ; to 0263 per cent, in Dundee ; and to - 370 per cent, in Glasgow. 



The following is the annual average proportion which the deaths by Bowel 

 Complaint, at different ages, bear to the whole annual average deaths by 

 that complaint, in different towns, and also to the population.
