"One great advantage claimed by the proprietor, and which commends itself at once to the judgment, is the simple construction, and more than that, the lasting nature of the valves. A ball, accurately fitting, supplies the place of the leather or India rubber valves most commonly employed. It is evident that an important object is here attained; the valves cannot get out of order. If, in taking the syringe apart, the ball should accidentally drop, it tells its story as it falls, and is instantly replaced; no renewal is needed, except there be actual loss, when a common marble, if round, will answer the purpose. "There are many occasions when it is necessary to use a thick, tenacious fluid for injections; for such purposes, this syringe can have no rival. With delicate flapping valves, these substances would decidedly interfere, and continual change and repair be demanded. With this simple and efficient arrangement, we can hardly conceive it possible for the instrument to get out of working order. In cases where it is imperative to give nourishing enemata, such as gruel, broths, &c., the above conditions are absolutely essential to success, and also to the final integrity of the apparatus. "As a general thing, the more simple the machinery, the easier its use, and the more universal its application. Complicated arrangements, while they are far more readily disordered, puzzle the unskilful, and sometimes even foil the accustomed hand: their fate is, commonly, to be thrown by in disgust. "Those who need such aids (and there are few who do not, occasionally, at least,) cannot do better than to supply themselves with this instrument. Every family should possess effectual artificial means of this description, to meet those exigences to which the sluggishness of nature or disordered health may give rise. Were enemata more used in this country, we could safely dispense with much purgative medicine given by the mouth; and when this can be done, we are sure that physicians as well as patients will gladly embrace the opportunity. "Printed directions accompany each box which contains the syringe. For travellers it is perfectly adapted, not only from its compactness, but from the ease of cleansing it. It is afforded at the very reasonable price of _three dollars and fifty cents_, and it deserves a large sale." _From the Boston Daily Journal, Dec. 18, 1855._ "LEWIS'S IMPROVED PORTABLE SYRINGE.--This is a new and beautiful instrument, which is worthy the attention of Physicians and families, and which we are confident will come into general use for the purposes for which it is intended. It is perfectly simple in its construction, and very efficient in its action, and it can be used by an invalid without any assistance or difficulty, and is not in the least liable to get out of order." _From the Boston Daily Chronicle, Dec. 5, 1855._
