812 TOUR OF LABORATORIES AT NATIONAL BUREAU OF STANDARDS
A guided tour of selected laboratories is planned for members of the Society and their guests on Thursday, June 14, to begin a t 2 P . V . Those members who wish to visit laboratories that are not on the guided tour can arrange for this when they arrive a t the burmu. Headquarters for all ACS visitors will be Room 214 Chemistry Building (Chemistry Lecture Room). The guided tour will include such activities as standards of
length and mass, the production and analysis of standard samples, micronave spectroscopy, the omegatron, and the determination of the gyromagnetic ratio of the proton. The tour will end at 5 p . x . at a tea to be held a t the residence of the director, Edward C. Condon, which is located on the bureau’s grounds. The bureau is located about 5 minutes’ distance by taxi from the Shoreham Hotel. A limited numbei of parking spaces J\ ill be reserved on the bureau’s grounds for privnte cars.
