ploy it. E. R. Squibb and Sons of Brooklyn use the International System 

 exclusively throughout, and have done so for eight years. They say : "If 

 we were back to avoirdupois, we should change again as in 1892." 



The very extensive works of the Solvay Process Company of Syracuse, 

 N. Y., employ the system in every possible way in the manufacture of 

 soda ash and bicarbonate. They use it for weighing coal and other sup- 

 plies, for water and other liquids, for the calculation of heat units and 

 measurements of temperatures, in fact for everything except linear measure- 

 ments, and such drawings as go outside of their own works. Their sales 

 are necessarily made by the English System. They say : " We find no 

 disadvantages, and would be very glad could our entire work be upon the 

 Metric System." 



The Merrimac Chemical Company, of Massachusetts, in 1893, built a 

 factory for their extensive sulphuric acid works, in which all the tanks 

 were made on Metric dimensions, so that one centimeter in depth equals 

 some number of liters, e. g., 100 or 150. They say : " We have found this 

 to be a great convenience, both in taking stock and in the daily work. 

 There was no difficulty in instructing the workmen to use the system." 



The Pennsylvania Salt Manufacturing Company has just built a large 

 plant entirely upon Metric dimensions. 



The Waltham Watch Company has used the Metric System exclusively 

 since 1869. They say : "It has proved to be exceedingly convenient and 

 satisfactory." 



William Sellers and Company have used it for injector work more than 

 forty years. 



The system is used almost entirely in the manufacturing of electrical 

 goods, and in electrical engineering. 



Makers of gauges, measuring implements, draughtsman's supplies and 

 the like, have some call for Metric instruments. 



Dealers in chemical and physical supplies for schools and colleges have 

 to use both the English and the French Systems. These dealers prefer the 

 latter, and use it whenever it is possible. All importations of glassware, 

 etc. , must be made on that scale. Certain goods are always made on the 

 Metric plan ; as, e. g., rubber stoppers. Teachers of science might, in a 

 small way, aid the cause by ordering all their supplies according to the in- 

 ternational system, instead of the English. 



The lyibrary Bureau of Boston, which has branch offices in the leading 

 cities of the world, is helping the cause. All its millions of cards and its 

 thousands of cases have exact Metric dimensions. Even the paper which 

 is made for the company is of Metric dimensions, and each variety is made 

 of a definite number of grams per square meter. They say there is not the 

 least difficulty in the application of these measures by the hundreds of 

 workmen employed in the manufacture of their goods. The system has
