NEW CHEMISTRY EXAM NSTA and ACS have pub lished a n e w chemistry test for high school students
A t Cornell University you'll f i n d almost 2 0 0 0 feet o f PYREX o i o e used f o r drainlines that must h a n d l e corrosive wastes.
LOOK! NO LEAKS! H o w Cornell University solved the p r o b l e m of d r a i n l i n e s for corrosives
Drainlines from the second floor School of Nutrition lab in Cornell's Savage Hall run slon° the cei!in°s of the first floor offices. Here, faulty joints were leaking corrosive damaging wastes. So out came the leaky lines and joints. And in went 700 feet of PYREX brand glass pipe. The people at Cornell have already learned about PYREX glass pipe from the 1200 feet that has been installed in Cor nell's Baker Laboratory of Chemistry. With PYREX pipe in, corrosion is out because this pipe is made from a glass that is not bothered by most acids or alkalies. No corrosion means no leaks.
And no leaks means no costly patchwork maintenance. If you visited the Cornell labs you'd see at a glance (this is transparent pipe) that all kinds of wastes go through—like litmus paper, cork, and pieces of tubing. If by chance blockage does occur—a rare happening because glass is so smooth— you can spot it at once, without costly dismantling. Finally, you will find that glass pipe is easy to install. Light in weight, it requires fewer hangers than lines made from other conventional materials. And you can get pipe and fittings in all the sizes you need. For complete details, send for Bulletin PE-30, "PYRJEX® pipe for drainlines." Write to Plant Equipment Sales, Corning Glass Works, 18 Crystal St., Corning, N.Y.

lOHM 1.959, a new high school chem istry test, will be ready for distribution on April 1. This is a year-end test d e signed for use by authorized chemistry teachers and administrators. It was prepared by National Science Teachers Association and the Examinations Com mittee of the American Chemical So ciety with technical advice from the Testing Bureau and Statistical D e p a r t ment of St. Louis University. Test items in the exam measure the degree to which a student has mastered the concepts considered significant by more than 40 experienced chemistry teachers. T h e new test evolved from try-out forms which were evaluated u n d e r ac tual classroom conditions. And great effort was made to reduce its reading difficulty. It consists of two parts, 50 items each. Each part can be completed in 40 minutes. Although the parts may be used alone, the Ex aminations Committee expects greater reliability when both parts are used. Test booklets and answer sheets come in multiples of 25. Booklets cost $4.00 a package and answer sheets, $1.00 a package. Further information on the exam may be obtained from Ex aminations Committee, ACS, St. Louis University, St. Louis 4, Mo.
