Saline-iron-hematoxylin has proved very satisfactory in teaching large numbers of Navy laboratory technicians the knack of identifying intestinal protozoa; less time is required than when the normal saline direct smear is used. From repeated observations, it is the general opinion that there is less eye strain, especially where several hours must be spent each day in examination of specimens. This solution has proved valuable in survey work. A positive specimen is detected more quickly, and the characters of the protozoa appear to be emphasized without any effect on trophozoite activity.
