Excerpt from Elementary Practical MathematicsReaders familiar with the published works of Prof. Perry, and those who have attended his lectures, will at once perceive how much of the plan of the book is due to his inspiration. But while claiming little originality, the writer has certainly endeavoured to give teachers of the subject the results of a long experience in instructing practical men how to apply the methods of the Mathematician to their everyday work. The exercises, which number close upon 1400, are either original or have been selected after careful consideration from public examination papers.The writer is glad to take this opportunity of thanking Mr. F. W. Arnold, for reading through the proof sheets, and to express his indebtedness to Prof. R. A.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
