photographers are seeking for them A negative Is I taken on an ordinary gelatine plain which has been prepared by treatment with a solu lion the Ingredient of which are tin known The negative thus obtained shows no trnco of color and appears In nil respects like any other photo graphic negative From It a print In I taken on ordinary albumenlted silver Paper which has been treated with tho before mentioned solution or It n transparency ls t desired on a gelatine late prepared In the same manner as hat which was used for the negative This print shows no trace of ojlor either by reflected or transmitted light The print when dry Is washed over with tho solution and Is I afterward treated successively with three colored olullons blue green and reelIho operation being conducted In a

detailed account has been given ti ° tho public by Prof C II Dtnjamln o f the Cast School ot Applied Science n t Cleveland 0 ot his recent experiment s In determining tho loss of power through friction In the transmlrslon by bells and shafting These observation were made In sixteen factories each engaged en-gaged In n different kind of work lie records the most startling loss to have been found In a bridge material factory where the shops were spread over a lot ot ground SO per cent of Ibo engine power was lost In tho shafting then In a planing mill the loss was 73 per cent nnd In a cowing machine factor U tvaa nearly 70 per cent It was 77 potent po-tent In a stamping mill and 65 per ccn t In a boiler and machine works Th e average loss for heavy machine shop was a little In excess of C1 per cent the average for light machine work was about f 3 per cent A lllrl Thai Wok In the bird store at 210 Sixth avenue New York there Is I a tiny bird a Meal L par an 4 e AI 1 can
