    I applied tests to the model to prove its strength, its ease of motion and its non-liability to get out of repair. What particularly renders your Leg preferable to all others, is the great simplicity and strength of all the joints. By their arrangement it seems impossible for the leg to break when any undue strain is put upon it. Indeed, the lightness, symmetry, and strength, combined with perfect ease of motion, renders it one of the most useful inventions of the age. As an illustration of its practical value I may instance a gentleman of my acquaintance who has two of these legs, (having tried others) and is able to walk with great facility. Very respectfully, I am your most obedient servant, ALFRED W. AVERY. Resident Surgeon to Conn. State Hospital. Ift. Avery is now Surgeon in the U. S. Army. Buffalo, N. Y., Oct. 31. 1862. D. DeForrest Douglass :—Dear Sir, From a careful examination of the mechanism of your Patent Artificial Leg in all its parts, and also from having witnessed its successful practical operation ; I have no hes- itation in recommending it as vastly superior to all other Artificial Legs with which I am acquainted, in firmness, durability, and the perfection of its operation, and especially the entire absence of the clumping sound that so often attends the step with an Artificial Leg. Very respectfully yours, C. C. WYCKOFF, Physician and Surgeon. Springfield, Mass., Oct. 12, 1861. D. DeForresx Douglass:—The Artificial Legs manufactured by yourself are worthy of all commendation, both for their simulation to the movements of the natural limb, and their durability. I give this assurance upon my own observation in cases of the loss of one, and both legs. Very respectfully yours, WM. G. BRECK, M. D. Springfield, Mass., Jan. 1859. D. DeForresx Douglass:—My Dear Sir, I have carefully examined the various Artificial Legs in this country and Europe, and can unhesi- tatingly say, in the Leg of your invention I find the principles of me- chanical science adapted and applied to anatomical purposes in such a form and manner as to produce the best mechanical compensation of lost parts that has come under my observation.
