Admittedly photomicrographs of three-dimensional parasite objects are difficult to produce and in doing so one is faced with decisions on what part of the object should be in focus to demonstrate certain morphologic features for diagnostic purposes. Some of the illustrations reproduced in this bench manual are excellent, but the majority lack sufficient clarity to be useful to either the student or the teacher who should not have to imagine that details are there. It is apparent that no attempts were made for color correction, lightening or darkening, etc. These shortcomings may be related to poor reproduction in a few of the illustrations, but initial selection may have played a greater role. Basically, the manual fails to fulfill the needs of the microscopist in laboratories engaged in diagnostic or didactic programs.
