Excerpt from Experimental Engineering
Materials under test are seldom so homogeneous that samples, taken even from the same piece, show exactly the same strength. In efficiency tests the personal error of the observer is usually such as to cause slight variations in the results from different observations. The results obtained in such work can therefore have no fixed and certain values, following known laws, but will approximate more or less closely to the average value which it is desired to obtain. In order to approximate as closely as possible to the result, it is desirable, where possible, to obtain the mean result from a series of experiments. Where it is possible to secure only single observa tions, it is necessary to take more than ordinary precautions in eliminating all possible sources of error.

Excerpt from Experimental Engineering
In attempting to revise the volume of Notes on Experimental Engineering compiled by the author in 1907, so much new matter was at hand and so many changes were found necessary that it was deemed advisable to rewrite the whole book. In doing this considerable matter belonging properly to the subject of experimental engineering has been brought in from other text-books.
The following authorities have been consulted: Carpenter's Experimental Engineering; Experimental Engineering, by Pullen and Popplewell; Physical Laboratory Notes, by Silas W. Holman; Barton's Internal Combustion Engines; Bieg's Text-Book on Naval Boilers; Departmental Notes; Smart's Laboratory Practice; Practical Cement Testing, by Taylor; Journal of the American Society of Mechanical Engineers; Journal of the American Society of Naval Engineers; Power and the Engineer; various manufacturers' pamphlets. The notes on the temperature-entropy diagram have, for the most part, been taken from the article on that subject by Lieutenant-Commander L. M. Nulton, U. S. N., published in the Journal American Society of Naval Engineers, Vol. VIII. The matter relating to time-firing devices has been supplied by Commander S. S. Robison, U. S. N., of the Bureau of Steam Engineering.
My thanks are due to Mr. F. H. Rittenour, draftsman in the Department of Marine Engineering and Naval Construction, for much valuable assistance in the preparation of the illustrations and to Mr. J. M. Armstrong for assistance in photographing apparatus. Also to the several manufacturers of engineering apparatus for their courtesy in supplying cuts of their laboratory appliances.
