Now that Cajal's great French classic from 1911 is available in a fine, fluent English translation, it should attract many to the text; not only to look at the illustrations and beyond to the passionately detailed descriptions, but also to savour the picturesque, and often belligerent, style in which Cajal describes the nervous system and some of its discoverers ... it is a book in which to gain an intimate acquaintance with an extraordinarily gifted, dedicated and original mind whose total involvement with the discovery, details and development of neurohistology and, perhaps most importantly, its functional interpretation, is communicated with clarity and excitement.
