Oratio de Quadr: Lunale Hypocratis, 1690
Item
Identifier: Coll-33/Folio C [190]
Scope and Contents
Graduation speech, in Gregory's hand, of one Laurence Oliphant. This young man may have been Gregory's future brother-in-law.
The subject is Hyppocrates' lunula. Two documents on the same subject come before this, no doubt as supporting notes. One is the draft of a letter from Gregory to Wallis, referring to a 1687 article by Tchirnhausen in the Leipzig Acta, the other, a transcript of that article.
