Invertebrate Nervous Systems

The authors are favored with a tidy, literate style, and the book makes straightforward reading. Illustrations are provided of each condition described and of the use of special techniques such as gel diffusion and immunofluorescence. These are of average quality, but are excellent when derived from the authors' own work, as on Sj6gren's disease. Each chapter has a fairly inclusive bibliography (221 references in the thyroid chapter for example). There are the usual minor, but always unfortunate, lapses in typography (Jankovic becomes Janovic throughout). All in all, this is an excellent, up to date book, which may be read with substantial profit by anyone entering the field and which adds new material for those already conversant with earlier volumes in this field.
