The Physio-Medical school commends the use of heat and moisture, bland diffusive stimulants, innocent astringents, of the character that may be taken in perfect health, in all the ways and to the extent ever required in disease, without seriously deranging the physiological state. Thousands of means and many processes are of this character, and may be used almost indifferently; but some of the best have been selected, as those that may be relied upon, since with them alone disease is treated and cured with as much directness and certainty as philosophical and chemical experiments are performed.

Indeed, it can be easily proved that the best philosophers and chemists fail more frequently in the performance of their projected experiments, than do the well instructed and faithful Physio-Medical practitioners in the cure of disease.

The conditions of their experiments being right, and the operators intelligent and skillful, both classes of operations are sure to produce the expected results. But sometimes the instruments or agents of both are defective, and then the results in neither case can succeed. The chemist can do nothing if his instruments are imperfect or his agents impure. So the doctor can not cure a far gone case of consumption with any medicine, nor any disease with spoiled medicines.
