A detail of such rails formerly usedat the Addey and Stanhope School (Fig. 47) is shown in Fig. SU ^^^ ^American physical bench possessing such rails, designed by Messrs. Alisonand Alison, who contributed the drawing, is shown in Fig. 52, while shows the very massive movable rail adopted by the Boston School-house Department.^ Probably, the balance of opinion in this country isagainst these rails, though means for suspension on a more limited scale^ From the report of this Department, Fig. 50.—Framing to Physical Laboratory Tables.
