Written in 1899 this book may seem far ahead of its time. It examines what is the best method to ventilate a building on the premise that the quality of the air breathed is of supreme importance. In this regard, the ideas presented were radical and far-sighted.

Excerpt from Natural and Artificial Methods of Ventilation: "A People's Health's a Nation's Wealth" Franklin This compilation is published with the view of demonstrating the comparative values of natural and artificial methods of ventilation, when the former is scientifically applied, and how ventilation may be successfully achieved with the simplest means by an intelligent comprehension of the laws which govern the movements of air and the utilisation of the powerful natural forces which are unceasingly in operation. The action of natural and of mechanical methods of ventilation is described and illustrated by diagrams, and an exposition given of the opinions held by the accepted authorities on the subject, with excerpts from the published accounts of their personal experience of the different systems. Extracts are also given from the official reports of Commissions on ventilation, appointed by the British, French, and American Governments, in which the evils of forced downdraught ventilation and of hot-air heating are described, and the dangers of open-window ventilation in cold weather. The evidence submitted in the following pages in favour of or against the respective systems emanates from well-known Scientists and Sanitarians whose names are a sufficient guarantee of the value of the statements they make and of the opinions they express. Theories are not dealt with, the results of practical work only being recorded. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
