56 DR. YELLOLY'S REMARKS ON THE 



instruments, as having been distinguished for his abilities in theology, physic, 

 surgery, and lithotomy*. 



From the establishment of the Norfolk and Norwich Hospital in 1772, to the 

 end of last year, making a period of fifty-six years, 649 operations of lithotomy 

 have been performed in it, which is at the rate of rather more than 1 1 ^ per 

 annum, and about 1 in 40 on the total number of admissions, which amounted, 

 in that period, to 26,52 1-|-. If we deduct from this number, the cases which 

 have come from Suffolk and Cambridgeshire, amounting to 74, (of which, 

 htawever, only a single instance has occurred from the latter county,) there will 

 remain 575 furnished by the population of the county of Norfolk, which amounts 

 to 351,000 ; and this will produce about 10.26 cases per annum, or 1 for every 

 34,000 inhabitants. 



The number of cases arising in Norwich;}:, in the same period, is 128, or 

 about one fifth of the whole ; while 447 are derived from the coimty of Norfolk, 

 independently. Norwich, therefore, which contains 50,000 inhabitants, fur- 

 nishes annually 2.28 cases on its population, or 1 for every 21,000 inhabitants ; 

 while the other parts of Norfolk afford only 7-98 per annum on their popula- 

 tion of 301,000, or 1 for every 38,000 inhabitants, which is not much above 

 one half of the proportion of Norwich. — Considerable differences likewise exist, 

 with regard to the ratio of numbers furnished by the different hundreds of 

 Norfolk ; the eastern parts of the county, however, contributing more largely 

 than the western. Thus the six western contiguous hundreds, including Lynn, 

 have furnished not more than one half of the proportion of the six eastern 

 hundreds, including Yarmouth ; and the difference is still more striking with 

 regard to some of the individual hundreds ; for the hundreds of Taverham, 

 Tunstead, and Walsham (contiguous hundreds on the eastern parts of the 

 county), have regularly furnished about five times the proportion of the con- 

 tiguous western hundreds of Freebridge Marshland, Freebridge Lynn, and

f The hospital contains about 100 patients, and averages about 80. — I have adopted the census of 

 1 820 in my calculations, and have usually put aside the hundreds. 



X With Norwich I include, as is usual, what is called the County of the City of Norwich, a district 

 which extends, in one direction, about two miles from the city, and in the others, from half a mile to 

 a mile.
