[528] On the properties and uses of _Mulsum_ in ocular medicine, see a full account in the Second Book of Alexander Trallianus, p. 176. [529] “Mollissimum genus earum _Penicilli_, oculorum tumores levant ex mulso impositi: iidem abstergendæ lippitudini utilissimi: eosque tenuissimos et mollissimos esse oportet.”—_Naturalis Historiæ_, liber xxxii. cap. xi. p. 289. In regard to the locality from which these sponges were procured, Pliny afterwards adds,—“Trogus autor est, circa Lyciam _Penicillos_ mollissimos nasci in alto, unde ablatæ sint spongiæ.”—_Ibid._ p. 290. [530] “_Penicillo_ fovere oculos oportet, ex aqua calida expresso, in qua ante vel myrti vel rosæ folia decocta sint.”—_Milligan’s Celsus_, liber vi. cap. vi. sec. 9, p. 288. When describing venesection at the bend of the arm, Celsus uses the word _Penicillum_ to imply the pledget or compress applied after the operation with the view of arresting the bleeding—“Deligandum brachium super-imposito expresso ex aqua frigida _Penicillo_.”—Lib. vi. cap. xi. p. 65. [531] _Milligan’s Celsus_, lib. vi. cap. vi. p. 284. [532] “Quo gravior vero quæque inflammatio est, eo magis leniri medicamentum, debet, adjecto vel albo ovi, vel muliebri lacte. At si neque medicus, neque medicamentum præsto est, sæpius utrumlibet horum in oculis _Penicillo_ ad id ipsum facto infusum, id malum lenit.”—_Ibid._ lib. vi. cap. vi. sec. 8, p. 286. [533] Deinde in balneo aqua calida quamplurima caput atque oculos fovere; tum utrumque _Penicillo_ detergere et ungere caput iridis unguento.—Lib. vi. cap. vi. p. 287. Scribonius Largus uses the analogous expression—“_Penicillo_ abstergeretur,” p. 232. [534] Igitur aversum specillum, inserendum, deducendæque eo palpebrae sunt: deinde exigua _Penicilla_ interponenda, donec exulceratio ejus loci leniatur.—_Ibid._ lib. vii. cap. vi. p. 342. After removing nasal polypi, he recommends a styptic tent, or, “aliquid ex _Penicillo_,” to be introduced into the nostrils (lib. vii. cap. x. p. 355). See also lib. vii. cap. iv. p. 324; and lib. viii. cap. ix. p. 425. [535] _Archæologia_, vol. ix. p. 240. [536] In his chapter on diseases of the eyes, after giving the formula for the _Basilicon_ collyrium of Euelpides—which was composed of poppy tears, cerussa, Asian stone, gum, white pepper, saffron, and _psoricum_—Celsus adds:—“Now there is no simple which by itself is called _Psoricum_; but a certain quantity of chalcitis, and a little more than half its quantity of cadmia, are rubbed together with vinegar, and this being put into an earthen vessel, covered over with fig leaves, is deposited under ground for twenty days, and being taken up again it is powdered, and is thus called _Psoricum_.”—See Greive’s _Celsus_, p. 343.
