![1st, In the vast majority of cases the general symptoms differ—i.e. of small-pox and scarlet fever. [This holds equally true with respect to the general symptoms of typhoid and typhus fevers.] 2nd, The eruptions, the diagnostic characters, if present, are never identical—i.e. in small-pox and scarlet fever. [The particulars detailed in the foregoing papers prove that this is as true of the eruptions of typhoid and typhus fever, as of those of small-pox and scarlet fever.] 3rd, The anatomical character of small-pox is never seen in scarlet fever. [Just in the same way the anatomical character of typhoid fever—i.e. lesion of Peyer's patches and the mesenteric glands —is never seen in typhus fever.] 4th, Both — i.e. small-pox and scarlet fever — being contagious diseases, the one by no combination of individual peculiarities, atmospheric variations, epidemic constitutions, or hygienic conditions, can give rise to the other. [I have here not attempted to determine how far this holds true with respect to typhoid and typhus fevers; but I have considered it in a paper read before the Medico- Chirurgical Society of London, December 1849,^ the contents of which I may anticipate so far as to state, that to my mind the origin of the two diseases from distinct specific causes, is as clearly proved as that scarlet fever and small-pox arise from distinct specific causes.] 5th, The epidemic constitution, favourable to the origin, spread, or peculiarity in form or severity of either—i.e. small- pox and scarlet fever—has no influence over the other, excepting that which it exerts over disease in general. [The facts detailed in these pages prove that this holds as true of typhoid and typhus fevers as of small-pox and scarlet fever.] If, then, the above are the grounds—and, after mature deliberation, I am able to assign no others—for the separation of small-pox from scarlet fever, I think it is indisputably proved, that typhoid fever and typhus fever are equally distinct diseases;—not mere varieties of each other, but ;pccifically distinct,—specific distinction being shown in ^ See page 139 et seq.](https://iiif.wellcomecollection.org/image/b2192272x_0149.jp2/full/800%2C/0/default.jpg)
