E. W. SCRIPTURE,\n(Director Yale Psychological Laboratory.)\n[Letter of Authorization.]\nThe great hindrance to the teaching of experimental psychology has lain in the lack of adequate, easily obtainable apparatus. In the past years I have tried to help along by manufacturing for others some articles in the laboratory workshop, but I have found it necessary to restrict this to a few special pieces. To overcome these difficulties, I have found an apparatus-maker who is willing to make pieces strictly according to my directions. In order that matters may be kept under proper control, the firm of Elmer G. Willyoung & Co., Philadelphia, has been constituted the sole authorized makers of all apparatus, diagrams, etc., listed under my name, which are required to experimentally illustrate my book, \u201cThinking, Feeding, Doing,\u2019\u2019 and also of some other apparatus of my invention similarly listed. All such apparatus has been made from designs and models carefully tested and approved.\nE. W.

The subject at once reacts and knocks down the two remaining sticks, making spark records, so that the first gives the reaction time, and the difference between the two the velocity of the blow. All this may be done by an arm movement of any kind and to any extent. The flag and the nearest stick form a signal and a reaction key for experiments on sight.

We have, in general, abandoned the idea of brilliant polish and lacquer, and design our products upon the same principles as would be used in machine designs, viz : finish and accuracy in functional parts, strength and dignified plainness in structural parts. In this way we are enabled to produce apparatus which, by its very appearance, invites use, at prices considerably less than would have been effected upon the old idea, thus allowing schools a much larger and more efficient equipment for the same amount of money.\nOur Catalogue N, of high grade college instruments of precision (largely electrical), is one of the most complete things of its kind ever published. Sent upon receipt of 25 cents in stamps.\nWe have catalogues on file from almost every instrument manufacturer of any importance in the world, and can quote prices. Our card catalogue enables us, often, to give information regarding instruments or instrumental methods otherwise almost unobtainable.\nWe are now preparing a line of instruments and apparatus suitable for the High School teaching of physics, and covering the branches of mechanics, hydrostatics, pneumatics, acoustics, optics, electricity, etc. A list of this will issue this fall.
