Excerpt from A Treatise on Ventilation, Natural and Artificial For simplicity and distinctness the work has been divided into five Chapters. The first chapter is devoted to the con sideration of ventilation in its chemical and physiological relations; in the second, natural or spontaneous ventilation is treated of and in the third, fourth, and fifth chapters, forced ventilation, and a number of the artificial and mecha nical agents employed to effect this, are described. In the works of others on ventilation where a systematic arrange ment is made, it has been the buildings or other places which have been so described; but in this, the different agents or instruments to effect ventilation have been classified, whilst a description of the buildings &c. Has not been overlooked. The subjects treated of are illustrated by numerous plams and woodcuts; and for convenience, a Summary of the whole treatise is subjoined. In treating a subject on which so much diversity of opinion exists, not only in theory but in practice, it has been the desire of the author, while giving his own views and opinions.

It is a quadrangle of 260 feet in length, by 154 in width, the sides of which are the north and south wings of the building. This building, which the writer has examined, stands in a somewhat exposed situation. The towers which lead to the sleeping-rooms are partly used as ventilating shafts through which a constant flow of pure air is kept up, while foulair shafts provide for carrying off the vitiated atmosphere from below. The partitions which separate the boys' rooms are carried up to within a few feet of the ceiling, so that the fresh air circulates freely along the whole length of the dormitory from north to south. The vitiated air from the dormitories is carried off by VENTILATED SPONTANOUSLY. Ill means of a horizontal wooden conduit, perforated with small holes, to ventilating shafts in the angles of the towers. In these shafts ring gas-burners are placed for the occasional rarefaction of the air. The fresh air is heated in winter by hot-water pipes, and enters the corridors of the dormitories through gratings in the floor. The same method of admitting the warm air is adopted for the Hall and School-rooms. From what has already been said about the inconvenience arising from admitting air by floor-gratings, as also extracting vitiated air at the lower part of rooms, it is sufficient merely to point it out, to show that there is little improvment of the system adopted at this building. It may be doubted whether any advantage can be derived from the dormitories communicating at the upper part of the partitions within a few feet of the ceiling; for instead of " fresh air circulating freely along the whole length, ..".
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.

Excerpt from Practical Treatise on Ventilation Organic chemistry has taught us that plants and animals, all organized bodies, not only depend upon the air for the continuance Of life, but that it is the Origin of the materials Of which these bodies are com posed. A knowledge of its constituents and of the changes it undergoes in these forms, so different from that in which we are accustomed to find it, cannot but be important for a change in its sensible properties, or even in the proportions Of its elements, must have an influence upon its dependents. As it is the Object of ventilation to afford a constant supply Of pure air, and remove that which has been deteriorated, it should be our first care to understand the properties Of pure air.
