The main object of pharmacology is to supply a basis for rational therapeutics. The entire medical profession has always been in accord as to the desirability of this end, but the methods of pharmacology did not at first secure universal recognition. This prejudice against laboratory experiments has now practically disappeared, partly through the advance of medical education and partly through mutual concessions. The modern physician realizes that rational therapeutics can not be based solely on bedside "experience," with its hastily and imperfectly observed and digested data. The phenomena in question are altogether too complex to be understood by such primitive methods. They need to be studied by the most delicate and profound methods over which modern science disposes.
