l'Etudiant Les Explosifs Modernes: Traité Théorique Et Pratique A L'Usage C42 Arch.

This book was  published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the   work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the  artifact. We believe this work is culturally important in its   archival form. While we strive to adequately clean and digitally enhance the   work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the   possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the   publisher.
