I was not known to any one; but the boatmen, frequently becoming sick, applied to me for medical aid; and hence I acquired the title of Doctor.

My prescriptions were always simple; and, strange to tell, I did not lose a single patient. My knowledge of the Materia Medica was, no doubt, limited.

This profession presents to the human mind the most extensive field for investigation. The great science of physiology is its basis; and chymistry, the wonderful magician, by whom
