says: "The new illustrated catalogue of physical apparatus just issued by Messrs. F. E. Becker and Co. (Messrs. W. and J. George, Ltd.) is likely to prove indispensable in the physical laboratories of all our schools and colleges. It runs to 628 large pages, and is strongly bound in cloth. Full particulars are provided, not only respecting the apparatus required in elementary and advanced physical teaching, but also concerning that necessary to the physicist in his research work. All branches of physics are included, and the lastruments throughout are explained by excellent illustrations and concise descriptions, and, what is of prime importance, the figure and its appropriate text are close together."
6 KNOWLEDGE" says: “Messrs. F. E. Becker and Co. (W. and J. George, Ltd., Successors) have sent us a copy of their new list of apparatus in the various departments of Physics, including Sound, Light, Heat, Magnetism, Electricity, Mechanics, &c. This exhaustive catalogue consists of over 600 pages and some 4000 illustrations. One of its noteworthy features is that the requirements of science teaching in this country and its colonies are always kept in view, and the articles listed cover the latest developments in their subjects. The method adopted in the list itself, together with the completeness of the index, is such as to make reference to it simple and expeditious."
66 SCHOOL WORLD” says: "The science-master in every grade of school should possess a copy of the new catalogue of Messrs. George, for he will find here particulars as to the available apparatus in sound, light, heat, magnetism, electri. city, mechanics, and other branches of physics, with information as to price and other necessary details. There is a profusion of well-drawn illustrations, which, together with the clearly expressed descriptions, will serve to explain to any buyer exactly what he is purchasing. This excellent catalogue will form a valuable addition to the reference library of any physical laboratory."
66 CHEMICAL NEWS” says: “Messrs. F. E. Becker and Co. (W. and J. George, Ltd., successors) have just issued a new Illustrated and Descriptive Catalogue of Physical Apparatus, &C., manufactured by them. This is the largest and best English catalogue of its kind printed, and comprises some 630 pages, and over 4000 illustrations; herein will be found all the newest up to date apparatus with all the latest improvements as manufactured at their works, while all obsolete apparatus has been omitted. The whole catalogue is arranged in a very clear manner under a number of principal headings, such as Magnetism, Heat, Sound, Light, Mechanics, Electricity, Pneumatics, Meteorology, X-ray Apparatus, &c., and a good index is provided; in fact, every. thing possible has been done to make this as perfect a guide as possible to users of apparatus in the subjects touched upon."
