This term is here employed, rather in reference to its origin than in accordance with its accepted meaning, to signify an increase in the quantity of the blood in general, or of its solid animalized ingredients. The circumstances of disease under which this remedial process is desirable are the opposite of those requiring depletion; namely, general debility, a too scanty blood, and a condition of that fluid in which, though its bulk may be sufficient, there is an undue proportion of the watery ingredient. The means by which it may be accomplished are the free employment of a highly nutritious diet, and the use of remedies calculated to invigorate digestion and sanguification, such as moderate exercise, tonic and stimulant medicines, frictions, and the cold bath.
