    AN EXPERIMENTAL INQUIRY INTO THE FUNCTIONS OF THE OPHTHALMIC GANGLION. By C. Radglyffe Hall, M. D., M. R. C. S. Eng. &c. PART FIRST. Incomplete as our knowledge of tlie physiology of every part of the nervous system undoubtedly is, it will be readily admitted that modern investigations have done less to elucidate the func- tions of the ganglia than of the other nervous centres. The ac- tions of the ganglionic system are indeed at present assumed rather than proved ; inferences from what is probable rather than de- ductions from established facts. There is great difficulty in sub- mitting any ganglion to satisfactory experimental procedure, and when this has been effected, the extensive connections of the gan- glion with other nervous centres render the results obtained com- plex and difficult of analysis. The lenticular ganglion represents the ganglionic system in miniature. What can be proved with respect to it, may justly be taken as a safe index to the rest. From being comparatively accessible, and from its connections be- ing limited and well-defined, this ganglion is the most eligible for the purposes of experiment. And from the effects produced on the eye being in great measure open to inspection, the results ob- tained are as little conjectural as the nature of such inquiries will admit of. The results of previous experiments on the nerves of the orbit A
