LSU Symposium The 16th Annual International Sym posium on Modern Methods of Analyti cal Chemistry will be held at Louisiana State University, January 28 to 31, 1963. The program will consist of in vited papers only, each speaker will have two hours to discuss topics of current interest. Time is provided for informal questions and discussions. In addition to the technical program, a display of modern laboratory equip ment will be provided. Registration is $16. Correspondence concerning regis tration and housing should be sent to Short Courses and Conferences, Gen eral Extension Division, Louisiana State University. Program information is available from Dr. P. W. West, Louisi ana State University, Baton Rouge, La.

ACS Pacific Southwest Regional Meeting The 1962 Pacific Southwest Regional Meeting, sponsored jointly by five sec tions: Southern California, Orange County, San Diego, Mohave Desert, and San Gorgonio, will meet at Pomona College, Claremont, Calif., Saturday, December 1. Four symposia, each of which has a few invited speakers and ample time for discussion, and four gen eral paper sessions are planned. Sym posia will consider the following topics : organoboron chemistry; reaction inter mediates of organic chemistry; chemis try in agriculture, present and future; and plasma chemistry.

New Variable Temperature Chamber for infrared studies above and below 0°C, using conventional sampling cells Newly developed at CIC is a Variable Temperature Chamber designed to oper ate ordinarily over a temperature rang ing from - 2 5 ° C to + 125°C. Lower operating temperatures are possible— perhaps down to liquid Nitrogen. The chamber mounts directly in the majority of commercial infrared spectrophotom eters and accommodates the majority of conventional liquid, solid and gas sampling cells. Heating and cooling of the insulated inner chamber is accomplished by using solid state "heat pumps", permitting rapid change of temperature and control
