Page 328 - Government in 1866. The three principal units are the meter, the unit of length, the liter, the unit of capacity, and the gram, the unit of weight. Multiples of these are. obtained by prefixing the Greek words: deka (10), hekto (100) , and kilo (1000). Divisions are obtained by prefixing the i.atiu words: deci d'à), centi (гДи)

Page 39 - D is the actual external diameter 71 of the tube throughout its parallel length, and is expressed in inches. Further back, beyond the perfect threads, come two having the same taper at the bottom, but imperfect at the top. The remaining imperfect portion of the screw-thread, furthest back from the extremity of the tube, is not essential in any way to this system of joint ; and its imperfection is simply incidental to the process of cutting the thread at a single operation. From the foregoing it follows...
