In trying to find out the modern point of view with respect to neuralgia due to involvement of Meckel's ganglion, I have read all the articles obtainable written in the last ten years. Twelve articles from the French journals were obtained from the Army Medical Library in Washington by photostatic reproduction.
Much careful work has been done on this fascinating subject. Larsell, Barnes and Fenton1 reported an experiment in which electrical stimulation of the sphenopalatine ganglion in the rabbit produced vasoconstriction of the vessels in the ear. Photographs were reproduced in which the larger vessels were reduced by 12 to 35 per cent of their size. The small capillaries disappeared entirely. When the cervical sympathetic trunk was cut, vasodilatation occurred, which did not change when the area of the ganglion was restimulated. As a controlling test to see whether fibers were carried through the fifth nerve, the maxillary nerve was
