Acoustical Holography An excellent article b y A. F . Metherell entitled "Holography with Sound" (Science Journal, 4, 57, N o v . 1968) is well worth t h e attention of those interested in t h e three-dimensional observation of objects. Advances in this field of research are rapidly being made, and applications in t h e realm of nondestructive testing and elec tronic detection appear t o be of urgent interest t o analytical scien tists. Other applications, such as underwater observations, geological and archaeological searching, a n d examination of t h e interior of t h e

H e r e ' sa0.3 meter plane grating Monochromator a snap
The reason? Snap-in gratings that are automatically in focus and alignment. The unique, snap-in grating system (pat. pending) of the McPherson Model 218 provides immediate installation (without special holders or further adjustment) of any one of 30 dif ferent gratings. So you're ready to operate instantly in any range from 1050A to 16M. An effective aperture ratio of f/5.3 with a special aspheric optical system (pat. pending) enhances the performance of the Model 218 resulting in a 1st order half-width resolution of better than 0.3A with a 2400L/mm grating. The Model 218 operates in any attitude, in the vacuum ultraviolet, ultra violet, visible, and infrared regions. Whether you're a chemist, biochemist, metallurgist, physicist, astronomer, space scientist, or educator, you get maximum flexibility from this compact, portable, automatic scanning monochromator. McPherson offers a complete line of precision instru ments for accurate analysis of the spectral range from soft X-ray to near IR. For complete information on the versatile Model 218 .3 meter scanning monochromator, write or call: McPherson is your exclusive U.S.A. distributor for the book ESCA by Kai Seigbahn et al, an important new work on electron spectroscopy for chemical anal ysis. $25.20 per copy.

Editors' Column human body in fantastic detail are equally interesting. The article is recommended reading for those interested in advances at the forefront of science. A Visit to Sadtler Laboratories Among the more pleasurable of our year-end travels, representing the Journal at a variety of meetings and functions, was a brief visit to Sadtler Research Laboratories in Philadelphia. Our host was Philip Sadtler, president of the 94-year old firm that was founded by his grandfather, the late Professor Samuel P. Sadtler, who was also instrumental in the founding of the ACS. Philip Sadtler has done a remarkable job in bringing his organization into the second half of this century as a thriving, 90-man organization whose services range from spectra generation, publication, and retrieval to a successful venture into education in the art of spectra interpretation. The well-known Sadtler infrared data collection is widely used in research laboratories for the identification of unknowns. Recently more than 50,000 spectra have been recorded on magnetic tapes according to absorption bands and chemical and physical properties. A rapid search of these infrared spectra for identification purposes can now be made in a matter of a few minutes, depending upon the type of computer used. Using a high-resolution AEI-MS902B spectrometer, the Sadtler group has tied into their IBM 360/30 computer to calculate exact masses and to print out possible formulas for each mass peak: capillary gas chromatography coupled into the system allows for component separations. The well-equipped Sadtler Laboratories are housed in a new 27,000 square foot building, and the organization has expanded customer service functions on NMR, DTA, UVvisible spectrometry, and gas chromatography. The present Sadtler organization is a credit to its founder and present leadership, and reflects the high quality of service that has been a tradition during its 94-year history of service to the chemistry profession.

Separate amines easily, efficiently with
New Chromosorb* 103
Chromosorb 103 is a polyaromatic porous resin developed by Johns-Manville as a solid-type support for the separation of amines and basic compounds. Until now, amine separation has been both laborious and difficult. With new highly selective Chromosorb 103, it's fast and easy. For more specific information, write for our bulletin FF-181. Johns-Manville, Box 290-C, gj-Jj Trenton, New Jersey. Johns-Manville •Chromosorb is a Johns-Manville registered trademark for its brand of products developed for use as support material or adsorbents for gas chromotography.
