The virtues of cinnabar and musk, against the bite of a mad dog, [electronic resource] : Illustrated, in a letter to Sir George Cobb, baronet. In which are recited upwards of a hundred cases, wherein this medicine hath happily succeeded: (whereof two were after the hydrophobia appeared;) together with some few instances wherein it hath not succeeded; owing entirely to its not being properly given, as is proved to demonstration: with proper directions whereby to avoid the like disappointment for the future.

By Joseph Dalby, surgeon.
