TO CALCULOUS DISEASES.

them. My own inquiries, in addition to the valuable information communi- 
cated by Mr. Hutchison, in the paper already referred to, enable me to state 
the proportional frequency of the disease in a few districts. 
The operations which have been performed at the Dundee Hospital, on cases 
belonging to Dundee, and to the county of Forfar generally, are about 54 in 
36 years, or 1.38 per annum*; this, as the population is 113,000, is at the 
rate of one case for 107,000 inhabitants. 
In the Aberdeen Hospital, the proportion is much more considerable ; for in 
the course of 77 years, as by a list which Mr. Cromar of that establishment 
was so good as to transmit to me, 285 operations have occurred, on cases 
belong to Aberdeenshire, and to the town of Aberdeen, containing together, a 
population of 155,000 ; which is at the rate of one case for every 42,000 inha- 
bitants. On the other hand, in the Hospital of Inverness, not more than 5 
operations, as Mr. Hutchison states, have occurred in the last 20 years, 
which, for the population of 90,000 contained in Inverness-shire, including the 
town of Inverness, is not at the rate of more than one for every 300,000 
inhabitants. But when it is considered, that this hospital is resorted to by the 
poor of the contiguous counties of Ross and Nairn, as well as by those of Cro- 
marty and Sutherland, the extreme paucity of stone cases, in this mountainous 
district, must be manifest. — In the Infirmary of Glasgow, 49 cases have occurred, 
in the course of 15 years, according to a list which Dr. Macfarlane did me 
the favour to forward to me, or about 3.26 per annum ; and of these, 31 be- 
longed to the city and suburbs, containing about 147,000 inhabitants, which 
is at the rate of 2 per annum, or one for every 71,000 inhabitants. The 
remaining 1 8 were from the country ; but I am unable to state the districts 
from which they were derived. There is reason, however, to suppose, that the 
tendency of the neighbouring counties to this disease, is very much less than that 
of Glasgow, for they have only afforded as small a number of calculous diseases 
as 18 to the Infirmary of that city, which may be regarded as the principal 
establishment for cases requiring capital operations in the West of Scotland. 
In the neighbouring town of Paisley, consisting of 38,000 inhabitants, 
about 18 cases have occurred in 10 years, all of them of poor inhabitants of
