Behold, then, our hero, all at once transformed from an unlucky urchin, running wild about the streets, to a student of medicine, diligently pounding a pestle, under the auspices of the learned Doctor Karl Lodovick Knipperhausen. It was a happy transition for his fond old mother. She was delighted with the idea of her boy's being brought up worthy of his ancestors; and anticipated the day when he would be able to hold up his head with the lawyer, that lived in the large house opposite; or, peradventure, with the Dominie himself. Doctor Knipperhausen was a native of the Palatinate of Germany; from whence, in company with many of his countrymen, he had taken refuge in England, on account of religious persecution. He was one of nearly three thousand Palatines, who came over from England in 1710, under the protection of Governor Hunter. Where the doctor had studied, how he had acquired his medical knowledge, and where he had received his diploma, it is hard at present to say, for nobody knew at the time; yet it is certain that his profound skill and abstruse knowledge were the talk and wonder of the common people, far and near. His practice was totally different from that of any other physician; consisting in mysterious compounds, known only to himself, in the preparing and administering of which, it was said, he always consulted the stars. So high an opinion was entertained of his skill, particularly by the German and Dutch inhabitants, that they always resorted to him in desperate cases. He was one of those infallible doctors, that are always effecting sudden and surprising cures, when the patient has been given up by all the regular physicians; unless, as is shrewdly observed, the case has been left too long before it was put into their hands. The doctor's library was the talk and marvel of the neighbourhood, I might almost say of the entire burgh. The good people looked with reverence at a man that had read three whole shelves full of books, and some of them, too, as large as a family Bible. There were many disputes among the members of the little Lutheran church, as to which was the wiser man, the doctor or the Dominie. Some of his admirers even went so far as to say, that he knew more than the governor himself-in a word, it was thought that there was no end to his knowledge! No sooner was Dolph received into the doctor's family, than he was put in possession of the lodging of his predecessor. It was a garret-room of a steep-roofed Dutch house, where the rain patted on the shingles, and the lightning gleamed, and the wind piped through the crannies in stormy weather; and where whole troops of hungry rats, like Don Cossacks, galloped about in defiance of traps and ratsbane.
