PREFACE.

This is a practical treatise showing the prevailing errors in the ventilation of churches, halls, schools, and other public buildings, and pointing out how the faults can be remedied. The information bearing upon the effects of wind action, and the intermittent air currents in public buildings, was obtained by experiments, or elucidated in the course of the author's practical experience, and these, together with the studies in the physics of ventilation set forth, cannot fail to be of value to architects and builders, as well as to ihe managers and caretakers of public buildings.

The author has endeavdured to 'cofnpress much practical matter into the smallest, compass, and the scientific and technical information regarding the composition of the atmosphere, its impurities, etc., has been omitted because it can be obtained in any book on physics.

Portions of the treatise have been compiled especially to enable caretakers to make the best use of the ventilating appliances which they have to control, and as there is no book on the subject, and great need for such information, it is hoped the matter provided will prove useful and instructive.

The illustrations are not intended to be complete drawings of the buildings in question, but are only given to show the air currents and other information in reference to the air supply.

London, 19o3.
