[229] British Museum, add. MSS. 24,068. This is a volume in 8vo containing a medical collection. It belonged in 1422 to Heinrich Zenner and afterwards to Magister Wenceslaus Brock. No. 22, at fol. 97vo, is as follows: ‘Pillulae Magistri Michaelis Scoti, quae fere competunt omnibus egritudinibus, et non possit scribi earum bonitas, unde nolo eas amplius laudare etc. Recipe Aloe epatice optimum, uncias iii., brionie, mirobolonorum indorum, reb. belliricorum, emblicorum, citrinorum, masticiis, dyagridii, azari, rosarum, Reubarbari an. unciam i.

It is as follows: ‘Pulvis Domini Fred. Imperatoris, valens contra omnium humorum exceptionem et precipue contra fleumaticum et melanconicum, ex quibus diuturnae infirmitates capitis et stomachi habent [?] provenire. Valet quippe contra defectum visus et stomachi debilitatem cibaria sumpta digeri et membris incorporari facit, valet contra stomachi ventositatem Scotomiam ante oculos inducentem, restaurat memoriam quocumque humore perditum, verum (?) dolorem ex frigiditate provenientem mitigat. Recipe: Carium, petrosillini anisi, marati, sexmontani, Bethonice, Cymini, calamite, pulegii, ysopi, spicenardi, piperis, sal gemme, rute, centrumgalli, herbae regiae, heufragie, olibani, mastici, croci, mirabolanorum, omnium, et plus de citrinis, an. ʒ 1. et utaris omni tempore indifferenter.
