Excerpt from A System of Physiologic Therapeutics, Vol. 7: A Practical Exposition of the Methods, Other Than Drug-Griving, Useful for the Prevention of Disease and in the Treatment of the Sick It seems appropriate therefore that a treatise like the present, emanating from Philadelphia, should give this subject its deserved prominence, probably for the first time in general therapeutic literature. Extremes, however, arc to be avoided in this, as in all other questions of therapeutic diagnosis. The editor trusts, therefore, that the judicious conservatism with which the subject has been treated by Dr. Pyle will be recognized and that the whole chapter on 'Physical Methods in Ophthalmic Therapeutics' will be found a safe and useful guide. Every physician needs to be able to judge whether or not the symptoms presented by his patients may be the result of ocular anomalies and should have an intelligent appreciation of the methods employed by specialists in studying and remedying such defects. The attention recently drawn to the bloodless method of reducing congenital dislocation of the hip, devised by Professor Lorenz of Vienna, will give to the article descriptive of this procedure a timely interest. Dr. Wilson's contribution, however, while it describes and illustrates Lorenz's operation comprehensively and in great detail, is not confined to this subject but also embraces many other methods for the skilful application of manual force to the correction of deformities of the osseous structures. The title 'Corrective Manipulations' has been adopted for the collective description of these procedures in order to avoid the apparent tautology of the perhaps more expressive title 'Manual Manipulations. The methods described are only those in which the correction is made by manual movements-manipulations in the most restricted sense of the term. While most of these corrective methods have been described in treatises and monographs in connection with other methods for the relief of the affections to which they arc applied, it is believed that this is the first time that they have been treated together and as a whole. It is hoped that this will serve to draw greater attention to 'Corrective Manipulations' and lead to a wider adoption of the practice. The article upon 'Exercise as a Method of Physical Education' has been given a separate place instead of being incorporated with the work of Dr. Mitchell, in order to emphasize the importance of the theoretic views advanced by Dr. Gulick, especially as to the correlation between the development of the race and that of the individual and the necessity for guiding the physical training of individuals on evolutionary and historical lines. The maxim that 'function makes structure' and its corollary that function is the guide for the exercise of parts, cannot lie too strongly emphasized.
