TENDENCY TO CALCULOUS DISEASES.

population, the records were not sufficiently ample to afford the requisite in- 
formation. I did not therefore, avail myself of the well known kindness and 
courtesy of the medical officers of other provincial establishments, to trouble 
them with inquiries, which the plan of their registers might not, perhaps, give 
them the means of satisfying. 
If I might venture, however, to make the suggestion, I would respectfully 
submit, how subservient our public hospitals, the boasts and ornaments of the 
country, might be made to important statistical inquiries, by a more extended 
system of registry, than is at present usually adopted, either in the metropolis, 
or in the country ; and how conducive to pathological improvement, the infor- 
mation would be, which they might thus be so readily enabled to furnish. 
The annexed Table will show the relation of calculous cases to population, 
in the principal instances which I have mentioned.
