S^r

I intended to have sent you y^e papers this week but upon reviewing them it came into my mind to w{illeg}|ri|te another little scrible to accompany them: y|Y|ou may expect 'em y^e next week. An ancient Gentleman I met at one of yo^r Assemblies (whose name I cannot recollect,) being thick of hearing desired me to inquire after y^e form of M^r Mace's Otocousticon a Musitian here; but he has not been in town since I came from London, but is somewhere in London about printing a book of Musi. Yet y^e last week I had opportunity to inquire after it of his son & he tells me the form is this. A y^e smal end to put into y^e ear BC y^e length suppose two foot CD y^e wide end suppose about eight inches over. The tube BDC tapers all y^e way almost eavenly like a cone {illeg} only at y^e great orifice CD widens more, like y^e end of a Trumpet. H{illeg}|e|{illeg} has of several sizes. The biggest do y^e best. If you can't reccollect who y^e Gentleman may be I suppose M^r Hill can tell you, for I think M^r Hill was by when y^e Gentleman spake to me, & y^e Gentleman desir'd me to write to either M^r Hill or you about it.

Yo^rs in hast
