[1] The learned Theophilus Bonetus observes, that this disease was unknown to Hippocrates and Galen.--Vide _Polyath. Lib. ii. Cap. xxviii. De Incubo et Catalepsi_. Unknown it could not be to such observers of nature, although they may not have written upon it. In the book however, ascribed to Galen, entitled “De Utilitate Respirationis,” the following short, but comprehensive notice, is to be found concerning it.--_Et Ephialtes quædam Epilepsia, quæ fit in somno: fit autem ex mistione tanquam Epilepsia. Ideoque non in vigilante, sed in dormiente: ut enim, prædictum est somnus et epilepsia fiunt in eodem loco, et ex simili causâ: unde Aristoteles dicit epilepsiam esse somnum quendam: verum ephialtes longo tempore perdurans in Epilepsiam convertitur._ [2] Memorat denique Silimachus Hippocratis sectator, contagione quâdam, plurimos ex istâ passione, (i. e. Incubo) velut lue, apud Urbem Romam confectos.--_Cœl. Aurel. lib. i. cap. iii._ de Incubone. [3] _Forrestus incubo affectus putabat, pectus suum comprimi a cane nigro, unde respirare non potuit, utut fæmina videret esse somnium fallax, uti de se refert._--L. 10. Obs. 51.
