I. Results of hemisection of the spinal cord in monkeys

While engaged in studying experimentally the connections of the cells of Clarke’s column with the ascending tracts of the spinal cord in the Monkey, I was surprised to find that after hemisection in the lower dorsal region, the sensory disturbances produced in no way corresponded with those already obtained by an eminent observer. I was, therefore, led to continue my experiments, with the aid of a grant from the British Medical Association, and by the kind permission of Professor Schäfer I carried them out in the Physiological Laboratory of University College. My thanks are also due to him for much valuable advice and assistance.
