The Prognostics and Aphorisms of Hippocrates are further illustrated by the learned and interesting Commentaries of Stephanus Sophista, Theophilus, and Damascius, which were published a few years ago by Dietz. From the nature of their works, it is impossible to give any satisfactory outline of their contents within our narrow limits. We shall merely give one specimen of them. It is stated in one of the Aphorisms of Hippocrates, that dyspnœa and delirium occurring together in fever, indicate a fatal termination. Upon which Theophilus and Damascius remark, that the one symptom implies disease of the heart and the other of the brain. (Ed. Dietz. T. H., p. 415.) Celsus gives an elegant translation of this part of the works of Hippocrates. The following is his version of the description of the Facies Hippocratica: “Ad ultima jam ventum esse testantur, nares acutæ, collapsa tempora, concavi oculi, frigidæ languidæque aures et imis partibus leniter versæ, cutis circa frontem dura et intenta, color aut niger aut perpallidus.” Other unfavorable symptoms are also strikingly portrayed: “Mali morbi testimonium est vehementer et crebro spirare: a sexto die cepisse inhorrescere; pus expuere; vix excreare; dolorem habere continuum; difficulter ferre morbum; jactare brachia et crura; sine voluntate lachrimare; habere humorem glutinosum dentibus inhærentem; cutem circa umbilicum et pubem macram, præcordia inflammata, dolentia, dura, tumida, intenta, magisque si hæc dextra parte, quam sinistra est; periculosissimum tamen est, si venæ quoque ibi vehementer agituntur.” Aëtius and Oribasius, like our author, borrow almost every thing from Hippocrates and Galen. Rhases and Avicenna, particularly the latter, treat of the prognostics in fever very fully. Avicenna, like Hippocrates, sets down deafness as an unfavorable symptom. Hippocrates had stated, that jaundice coming on before the seventh day is unfavorable; but Averrhoes affirms, that all the Indian and Persian physicians reckoned it a favorable symptom. Rhases considers yellowness of the skin an unfavorable symptom, unless the fever be of a bilious nature. Alsaharavius says it is an unfavorable complication when it does not prove critical. It is proper to mention here that Hippocrates modifies the above prognostic by stating in one of his aphorisms, that jaundice coming on on the 7th, 9th, 11th, or 14th day is favorable. (iv. 64.) Alsaharavius states it as a dangerous symptom, when the patient lies on his back with his legs drawn up. This agrees with the prognostic of Celsus “Mors denuntiatur ubi æger supinus cubat, eique genua contracta sunt.” Avicenna and Averrhoes state it as a fatal symptom when the patient sinks down in bed and exposes his hands and feet. (Averrhoes, Comment. in Cant. Avicennæ.)
