The design and operating conditions for a spark chamber used in a e (as Fe/sup 59 /sup -/ + p experiment at the Cosmotron are described briefly. Photographs are shown illustrating the considerable differences observed in spark densities of the four tracks of a given event. The relative track densities were compared with the particie velocities calculated from the reaction kinematics. An almost complete correlation was found, the lower-velocity particles were making the denser sparks. Effects other than ionization, which are important in determining spark density and must be taken into account in particle identification, are considered. (A.G.W.)
