![was of the same nature as small pox. Navier (a French author), in 1753, traced the relation subsisting between scarlatina and the distemper of horned cattle, and came to the conclusion that scarlet fever was originally com- municated from cattle to man. In some cases the body receives at one and the same moment the germs or miasms of two exanthemata, and though they occasionally proceed pai'i passu, the more usual law is that of suspension. Generally the lesser exanthem is suspended by the greater. Measles is sus- pended by small pox. Cow pox is held in abeyance by measles; but instances of the reverse proceeding are on record. [For cases illustrating the co-existence of two febrile exanthemata in the same individual, and the suspension of one by another, see Appendix C] The connexion of exanthematous eruption with a like affection of those mucous expansions or tissues which are in contact with the atmospheric air, and exposed to its direct influences, claims your especial attention. It is a feature in the eruptive fevers of the highest importance both in theory and practice. A reason may be found for this connexion in the similarity of the structure and offices of skin and mucous mem- brane. The epithelium of the one corresponds with the epidermis of the other. The result is, that all such mucous membranes are susceptible of the changes of efflorescence, papula, vesicle, and pustule. Small pox, measles, and scarlatina, alike exhibit, in their early stages, affection of mucous surfaces,—either of the nose, mouth, fauces, larynx, or trachea. Erysipelas some- times betrays the same tendency, and this strong dispo- sition of the morbid poisons to affect the throat is still](https://iiif.wellcomecollection.org/image/b21055257_0036.jp2/full/800%2C/0/default.jpg)
