 though in such a crowd of invalids, old fractured 

 bones must be frequent; and even, since Mr. de F.'s 

 case has been related by Dr. Hufeland, who did not 

 draw the same conclusion from it as his readers have

 ingredients, the expressions of strong and mild 

 fountains are in general used at Carlsbad , instead
