Easton's 1897 Bible Dictionary:

Physician
   Asa, afflicted with some bodily malady, "sought not to the Lord
   but to the physicians" (2 Chr. 16:12). The "physicians" were
   those who "practised heathen arts of magic, disavowing
   recognized methods of cure, and dissociating the healing art
   from dependence on the God of Israel. The sin of Asa was not,
   therefore, in seeking medical advice, as we understand the
   phrase, but in forgetting Jehovah."


Bouvier's Law Dictionary, Revised 6th Ed (1856):

PHYSICIAN. One lawfully engaged in the practice of medicine.
     2. A physician in England cannot recover for fees, as his practice is
altogether honorary. Peake C. N. P. 96, 123; 4 T. R. 317.
     3. But in Pennsylvania, and perhaps in all the United States, he may
recover for his services. 5 Serg. & Rawle, 416. The law implies, therefore,
a contract on the part of a medical man, as well as those of other
professions, to discharge their duty in a skillful and attentive manner; and
the law will redress the party injured by their neglect or ignorance. 1
Saund. 312, R; 1 Ld. Raym. 213; 2 Wils. 359; 8 East, 348.
     4. They are sometimes answerable criminally for mala praxis. (q.v.) 2
