Lantern Slide Bulletin W i t h t h e 125th National ACS Meet ing just a r o u n d t h e corner (Mar. 23 to Apr. 1 ) , some information on prepara tion of lantern slides m a y come in h a n d y for prospective speakers. A bul letin prepared by t h e Division of Rub ber Chemistry furnishes t h e essential information. According to the bulletin, a chart or a curve on a slide is only an illustra tion, presupposes verbal explanation, and is usually incomplete in itself. A slide should present only one central idea and b e free from all lettering and lines which are not essential. Poor preparation of ( t h e slide's) drawings is t h e most usual fault. Di mensions of 7 by 9 inches are recom m e n d e d in preparing drawings. T h e photographer should be instructed to include this entire area in t h e field of his picture which reduces to 2 3 /s by 3 inches. Also r e m e m b e r that slides are designed for horizontal projection only and that the whiter the p a p e r the bet ter. O n the 7 b y 9 inches drawing, type written letters are never satisfactory.
Smallest letters should consist of capital
Gothic letters, τ/4 inch high b y 3 / e 4 inch wide. If a Leroy lettering set is used, template 240 and pen 5 should b e used for titles and template 200, pen 4, for all other letters. All curves should be 1 / 1 6 inch wide—Leroy p e n 6. Coor V O L U M E

dinates can be l/ss inch wide—Leroy pen 3. Using an average of seven letters per word, slides of graphs should not h a v e more t h a n 20 words, and this includes any and all letters or numbers used. Slides w i t h formulae or data summaries should not contain more than 50 aver age words—350 individual letters and digits. Lantern illumination must be suffi cient to insure a reflected light level of 10 foot-candles at the screen. Rela tions between room length and mini m u m picture size, in feet, a r e : lOOM
