Special action upon the case, wherein the plaintiff declares that the defendant _Baker_ being a surgeon, and _Stapleton_ an apothecary, he employed them to cure his leg which had been broken and set, and the callous of the fracture formed; that in consideration of being paid for their skill and labour, &c. they undertook and promised, &c. but the defendants not regarding their promise and undertaking, and the duty of their business and employment, so ignorantly and unskilfully treated the plaintiff, that they ignorantly and unskilfully broke and disunited the callous of the plaintiff’s leg after it was set, and the callous formed, whereby he is damaged. The defendants pleaded not guilty, whereupon issue was joined, which was tried before the Lord Chief Justice _Wilmot_, and a verdict found for the plaintiff, damages £500. The substance of the evidence for the plaintiff at the trial was, first a surgeon was called, who swore that the plaintiff having broken both the bones of one of his legs, this witness set the same, that the plaintiff was under his hands nine weeks, that in a month’s time after the leg was set, he found the leg was healing and in a good way; the callous was formed, there was a little protuberance, but not more than usual; upon cross examination he said he was instructed in surgery by his father, that the callous was the uniting the bones, and that it was very dangerous to break or disunite the callous after it was formed. _John Latham_ an apothecary swore he attended the plaintiff nine weeks, who was then well enough to go home, that the bones were well united, that he was present with the plaintiff and defendants, and at first the defendants said the plaintiff had fallen into good hands; the second time he saw them all together the defendants said the same, but when he saw them together a third time there was some alteration, he said the plaintiff was then in a passion, and was unwilling to let the defendants do any thing to his leg; he said he had known such a thing done as disuniting the callous, but that had been only when a leg was set very crooked; but not where it was straight. A woman called as a witness, swore that when the plaintiff came home he could walk with crutches, that the defendant _Baker_ put on to the plaintiff’s leg an heavy steel thing that had teeth, and would stretch or lengthen the leg, that the defendants broke the leg again, and three or four months afterwards the plaintiff was still very ill and bad of it.
