5 Introductory Renarks With the present set of primary scattering functions, the entire field of light scattering by spherical particles in a liquid medium is covered within the range of particle sizes where light scattering is of interest as a tool. Light scattering by spherical particles in a gaseous medium is completely covered by a parallel investigation under the direction of Dr. Sliepcevich at the University of Michigan. The application of the Mie equations in the form of practically useful quantities, which had been due for 1+5 years, has therefore been completed, by two independant projects, which, curiously, were not aware of each others existence until very recently, inspite of their proximity. Later this year, the present material will be integrated with that brought in the Technical Reports 2 and 3 to form a single revised Report under suitable change of page numbers and under elimination of textual material not needed or duplicated. The machine computation was carried out by Mr. James McCarty and Mr. Lyle Langdon of the Computation Laboratory. Proof reading and supervision of the assembly of the mimeographed material w-vs carrid out by Mr. R. Tabibian and Mr. T. Puph. W. Hell].er
