This little manual will be gratefully received by all students of comparative mammalian neuroanatomy and all medical students who begin their study of the gross anatomy of the brain with the brain of a sheep. The book is clearly and simply written. In fact it at times descends to a juvenile level somewhat beneath that of the students for whom it is intended. The text presents a carelessness with the English language, a colloquialism, not anticipated in a book from this source. For instance, the author uses "pia" for pia mater, "medulla" for medulla oblongata, "cranial" for cranial nerve, "pituitary" for pituitary body, and so on. "In front" and "behind" are used to mean ventral and dorsal as well as cephalad and caudad, at times in the same or neighboring paragraphs and to the confusion of the reader. The illustrations, pen and ink drawings by the author, are very good.
