    From the brief summary I have given of the labour's of the pathologists of the French school, it will be observed that the evidence deducible therefrom is of such a conflicting character, as to leave quite unsettled the complex question of the localisation of the faculty of speech. The history of the continental contributions to the literature of aphasia would, however, be very incomplete, without a brief glance at the researches of the German and Dutch physiologists. Schrcoder van der Kolk,* in his chapter on the ac- cessory ganglia in the medulla oblongata, endeavours to establish a close physiological and pathological con- nection between the function of articulation and speech and the corpora olivaria. Besides citing numerous cases in illustration of his hypothesis, he gives an a priori reason for his theory in the fact that the corpora olivaria occur only in mammalia—that on comparing these organs as occurring among mammalia themselves, it is to be observed that they nowhere exist on so extensive a scale, and are so fully developed, or present so strongly plaited a corpus ciliare, as in man; that in * On the Minute Structure and Functions of the Spinal Cord and Medulla Oblongata.
