It does not, however, follow, from this, that there is any necessary proportion in the degree of prevalence of scrofulous phthisis and the other forms of scrofula; on the contrary, it is possible that where the morbid diathesis manifests itself strongly in one form, it may do so feebly in the others. It would not follow, therefore, as a matter of course, that consumption must he a very prevalent disease in this district, even if it were fully established that external scrofula were so.
It is hardly necessary to remark, that my own observation, and the testimony of the local practitioners, go to establish the existence of consumption as a disease of very frequent occurrence; because it will be universally admitted that it is so in every part of England, and, indeed, it may be said, in every part of Europe, if not in the world. Without referring to statistical documents, l should say, as a general observation, that consumption is as prevalent in the Landsend district as in Sussex; and that it is more prevalent in both than in Scotland.
