683. Idiosyncrasy.

By this is meant a peculiar temperament or disposition not common to people generally. For example, some persons cannot take calomel in the smallest dose without being salivated, or rhubarb without having convulsions; others cannot take squills, opium, senna, &c.; and this peculiarity is called the patient's idiosyncrasy, therefore it is wrong to _insist_ upon their taking these medicines.
