Abstract

THE testing and inspection of the material and apparatus used in the British Post Office is an operation of great importance and requires the services of a large staff. The Post Office issues invitations to tender for telephone and telegraph apparatus and material, and as a rule the manufacturer quoting the lowest price obtains the contract. The manufacturers, therefore, have to be furnished with a satisfactory specification, and must have an assurance that nothing inferior to the standard specified will be accepted. Fully equipped mechanical, chemical, and electrical testing laboratories are necessary, and the inspection and testing of the tenders requires thorough knowledge, high skill, and lengthy experience. Mr. Henley's book gives many theorems in chemistry, mechanics, physics, and mathematics which have direct applications in practice. The subject is one of ever-increasing importance, and only those engaged in everyday testing are fully aware of the many assumptions that have to be made in theory and how these assumptions limit the application of ordinary academic methods. Mr. Henley gives a great deal of interesting information which will be of value to the scientific worker and will show him the type of problem in which the practical man will be grateful for his help.
