Hoods warn by Doctors of Divinity of Aberdeen

Will you allow me to inquire, through the pages of your publication, of what *colour* and *material* the *exterior* and *lining* of hoods were composed which Doctors in Divinity, who had graduated at Aberdeen, Glasgow, and St. Andrew's, prior to the Reformation, were accustomed to wear? I imagine, the same as those worn by Doctors who had graduated at Paris: but what hoods they wore I know not. I trust that some of your correspondents will enlighten me upon this subject.
