IN the preparation of this little book it has been the author's aim to furnish medical students with a clear, accu rate, and concise account of the anatomy of the brain, to be used as a guide in their study of that organ. From a work of this character it has been thought best to omit minor de tails, and to exclude, so far as seemed possible, subjects which are still matters of controversy. Recognizing the value of a uniform nomenclature, use has been made of the Latin terms adopted and recommended by the German Anatomical Society at its meeting in Basel, to the extent that they have been inserted, parenthetically.
