Excerpt from A Practical Treatise on Materia Medica and Therapeutics The appearance of the sixth decennial revision of the United States Pharmacopoeia has imposed on me the necessity of pre paring a new edition of this treatise. I have accordingly adapted the Work to the official standard, and have also given to the Whole of it a careful, revision, incorporating the more recent improve ments in the science and art of therapeutics. Many additions have been made, and parts have been rewritten. These additions and changes have added about one hundred pages to the body of the work, and increased space has been secured in some places by the omission of the references. In the new material, as in the old, practical utility has been the ruling principle, but the seien tizfic aspects of therapeutics have not been subordinated to a utili tarian empiricism. In the new matter, as in the old, careful consideration has been given to the physiological action of reme dies, Which is regarded as the true basis of all real progress in therapeutical science; but, at the same time, I have not been un mindful of the contributions made by properly conducted clinical observations.
