What was advertised in a revolutionary American newspaper 250 years ago this week?

“For the benefit of others I desire that you may make my case public, that those being imposed upon and labouring under the same complaint may know where to apply for a cure.”
Testimonials worked! Anthony Yeldall must have thought so because the apothecary repeatedly included testimonials from grateful patients in his newspaper advertisements. Perhaps some patients mentioned testimonials they read in his advertisements when they consulted him “at his Medicinal ware house” in Philadelphia, prompting him to publish more testimonials. The testimonials often accounted for much more space than any copy that Yeldall wrote himself. His advertisement in the August 3, 1776, edition of the Pennsylvania Ledger, for instance, consisted of five paragraphs. The last four were testimonials that his patients stated that they wanted published “[f]or the benefit of others.” It was one thing for the apothecary to claim that his “Abilities are well known through most parts of the United Colonies,” but the testimonials demonstrated that was indeed the case. Joseph Spenser, “Grocer in Second-street,” Benjamin Wilson, “Elizabeth-town, New-Jersey,” Christopher Hughes, “Bedminster-township, Bucks County, Pennsylvania,” and William Bell, “Vincent township, Chester County, Pennsylvania,” each praised the treatment that “DOCTOR YELDALL” provided.
Those testimonials had some common features that suggest Yeldall may have worked with his patients in composing their testimonials or they may have used testimonials that appeared in previous advertisements as models. Three of the testimonials began with “For the benefit of others” and a request “that my case may be made public” (or some close variation of that phrase). Hughes expressed similar sentiments but deviated from the formulaic language used by the others: “being desirous that they may reap the same benefit that I have done, I desire that you may make my case public.” Each testimonial made clear that Yeldall published success stories at the behest of patients he returned to good health. They did not make their way into print solely due to the self-interest of an apothecary seeking more patients. Each also told a frustrating story about seeking medical care from physicians and surgeons whose assistance proved ineffective before turning to Yeldall for treatments that returned them to full health. Spenser, for instance, “applied to several able Physicians in the city, but could find no relief” for a pain that cause him to lose the use of his arm. He then turned to Yeldall, “who in a short time removed the pain, restored the use of my arm, and I now follow my business.”
Yeldall certainly considered testimonials effective when he decided on his marketing strategy. He would not have continued to publish them (and invest so much in the space required for each testimonial) if he did believe that they yielded a return on his investment in placing them in the public prints. He likely appreciated that testimonials helped build trust with patients before they even consulted him for “advice and medicines.”
