In the 10th picture Dyott describes the medicne being put into square flint glass bottles with the following pressed into the glass Dr. Robertsons Family Medicine, Prepared Only By T. W. Dyott.Well now we have an ad listing the embossed bottle in July of 1809.
For easier reference here is the ad highlighted in red.I have an 1807 Philadelphia paper with a Dyott ad in it .As soon as I find it I will post it.He also states that the bottles are American manufactured.This tells me they came from the Heston Carpenter (Olive Glass Works) or the Gloucester Glass works both in New Jersey as they were the only local plants and Dyott had been visting them quite often
The Olive glass works of GLassboro New Jersey advertised that all of their product line could be purchased at Dyotts warehouse on the front page of this newspaper.On the same newspaper The Harmony Glass works also of Glassboro New Jersey 400 yards south of the Olive advertised on the front page also and state not not a quack proprietor an obvious jab at Ed Carpenter the owner of the olive glass works.
