(_Phil. Gabr. Hensler_, ““Program” (College Exercise) on the _Herpes_ (Creeping eruption) or _Formica_ of the Ancients,—a Malady not unconnected with the Venereal Disease.” Kiel 1801. pp. 64. 8vo.) This “Program”, which _Hensler_ wrote on his resignation as Dean and for the Public Announcement of certain Graduations, is divided into 10 Divisions, of which Div. 1 gives a survey of the Contents, Div. 2 considers certain passages from the genuine Writings of Hippocrates (Prorrhetic. 11, 18, 21, “de aere, aquis et locis”—“of the effects of air, water and locality”, II. Aphorism. V. 22.) dealing with _Herpes_, from which we gather that under the name _Herpes_ were understood eating (phagedenic) Ulcers, that the _Herpes esthiomenes_ attacked especially the abdomen and the Genitals, that _Epinyctis_ was pre-eminently a disease of adults, whence a suspicion arises of its being communicated by coition. Div. 3 gives medical opinion on the different kinds of _Herpes_ down to _Celsus_. Div. 4 gives the same on _Epinyctis_, special importance being given to the pains at night. Div. 5 discusses the _Therioma_ of _Celsus_ (V. 28. 3.), which according to _Pollux_, Onomast. IV. 15., specially affects the Genitals, and is closely akin to the _Epinyctis_. Div. 6 gives the views of _Galen_ on _Herpes_. Div. 7. The Author proceeds to the _Formica_ of the Arabians, and shows that they have designated several distinct Skin-diseases by this name. Div. 8 treats the views held by Arabic writers down to the XVth. Century; whilst Div. 9 gives the shape these views took _during_ the XVth. Century. In Div. 10 _Hensler_ draws the following conclusions from the evidence he has adduced: _Formica_ was the same thing as the _Herpes_ of the Greeks; under both names, yet by no means exclusively, were indicated syphilitic affections. Immorality at all periods generated Venereal Disease, which arose at first rather sporadically, but towards the end of the XVth. Century in consequence of its universal diffusion became virtually epidemic. The early neglect of Etiology, as well as the Galenian hypotheses of deteriorations of the humours, stood in the way of the right understanding of the Disease. Venereal Disease is not a single Malady, but a Diathesis (General Condition of Body), which in accordance with time and circumstances may manifest itself in different forms. “Hujusmodi vero lues mihi illa _omnis_ esse videtur, quae _ipso coitu_, quo quidem loco luis praecipuus focus est, facillime cum aliis _communicari_ et ad ipsam prolem propagari possit. _Summa_ ejus _genera_ esse equidem arbitror _Lepram_, malum, quod _Pians_ vocant, ipsamque Syphilidem.” “This contagion seems to me to be a general one, and of this sort that it is capable of being very readily communicated to others by the act of coition, where indeed is the chief _nidus_ of the Disease, and of being propagated even to posterity. Its main forms are, in _my_ opinion,
