This publication is intended to cover gas as a weapon in war, the resulting after effects, the humaneness of its use and casualties resulting from the use of gas in comparison with casualties from other weapons. Please note this a reprint from the archives and while we have made extensive efforts to clean up text and photographs the quality sometimes reflects the age of the original document and the typefaces available. Photographs and maps are included but there may be inconsistencies in appearances. These are not cheap OCR editions and the book is checked for legibility throughout.
