might depend upon the diet of its inhabitants, consisting 

 chiefly of what is termed " Norfolk dumpling." Mr. Burnard 

 remarks, that the chepatees of the Hindoos of the Upper 

 Provinces are a very similar kind of food, and may at least 

 have some secondary influence in the production of stone. 

 This opinion has been repeated by later writers. 



From information kindly afforded by Mr. Forsyth, it would 

 appear, that Calculus is more common in the Upper Provinces 

 than in Bengal, and that operations for stone have been most 

 common at Cawnpore, Agra, Muttra, and Delhi. They have 

 not been unfrequent at Benares, Allahabad, Bareilly and 

 Jubbulpore, but have been far more frequent at Delhi than 

 at any other station. It would be curious to ascertain whether 

 the prevalence of Calculus at most of these places may not 

 be connected with the kunkur, and at Jubbulpore, with the 

 beds of limestone which prevail to some extent in the 

 coal formation ; but we cannot venture to theorise on the 

 subject. 



As connected in some degree with this subject, we quote as 

 follows from the " British and Foreign Medical Review" for 

 July, in a notice of a Thesis of Dr. Falck's on Bronchocele : — 



" 1 . Although different authors have found bronchocele to 

 be accurately confined in certain districts to particular strata 

 of rocks, as in Kumaon, according to McClelland, to transi- 

 tion limestone : in Wurtemberg, and according to Riedle, to 

 shell limestone : in England and in Siberia to magnesian 

 limestone : in Hesse to shell and magnesian limestone : in 

 Switzerland to transition limestone and nagelflugh, yet in 

 several districts situated on similar formations, as in Wolf- 

 hagen and Hof Geismar, bronchocele rarely occurs. 



" 2. The assertion of McClelland that bronchocele is infre- 

 quent in districts where the primitive strata prevail, is op-
