Carbon-14 has been used to study the composition of the product of benzene alkylation with the propane-propylene fraction of pyrolysis gas. Radioactivity was measured by internal filling and mica-window counters.

Analytical Chemistry Division Gains M e m b e r s Membership in the AMERICAN CHEMICAL SOCIETY'S Division of Ana­

lytical Chemistry increased from 2300 in 1956 to 2700 in 1957, according to the division's semiannual report. War­ ren W. Brandt, secretary-treasurer of the division, also reported that the 1957 Directory of Members was sent out in September. The volume, produced by W. C. Ellenbogen, was financed by the

Fisher Scientific Co. Members who have not received a copy may obtain one by writing the secretary at the Department of Chemistry, Purdue Uni­ versity, Lafayette, Ind. Brandt also made the plea that, in case of a change of member's address, he be notified directly. He pointed out that notifications made to the Wash­ ington ACS office are not ordinarily passed on to the divisional secretary. The result is that many members each year find themselves not receiving ab­ stracts and other papers to which they are entitled.

Kontes functionally designed Outer Ground Joints have unusually heavy top beading, thick, high-strength walls . . . and, in contrast to socalled "ring joints", no external ridges or bulbs. Outside diameter is uniformly cylindrical. There are no thin spots. All Kontes Outer Ground Joints conform to Ν BS specifications in every respect. The result isfaster, more secure clampingand apparatus assembly, less chance of chipping and cracking, better fits and com­ plete interchangeability.
