    stated that proptosis was present, without any mention being made of the direction of the bulging. It is probable that the greater number of these were more or less direct, else had the fact been otherwise noted. Granting even this, the exceptions still form a large percentage of the cases, and we must conclude therefore that while proptosis in or about the orbital axis is someivhat characteristic, too much stress is ?iot to be put tipon it as a sign of primary ticmours of the optic nerve. B. The Development of the Proptosis : This feature, expressive for the most part of the rate of growth of the tumour, is, in the great majority of instances, slow and evenly progressive ; exceptions to the rule are comparatively few in number. In the cases of Narkiewicz-Joko,'^ Vossius,^^ Hessdorffer,^^ and Braunschweig ^4 (3rd), the onset of the exophthalmos was rapid; in the instance of Wishart,' the proptosis developed quickly during the first year and then remained stationary in degree; in Frothingham's second growth, the proptosis became very marked in a short time after long persisting in a slight degree ; and the relations of yossius'38 first patient gave a history of very marked increase m the exophthalmos having occurred during a single night Buller,9^ Rampo]di,34 Willemer^9 (ist)^ Gardner (this paper), and De Vincentiis,^^ ^Iso noted accelerated augmentation of the proptosis at different periods of its development. In the last mentioned instance, the increase seemed to follow the examination by palpation. Variations in the degree of the exophthalmos were observed in Vossius'^^ third patient and the same phenomena, at the time of the menstrual periods, were noted by Norton^^ and Brailey.^4 j^e most remarkable instance of this kind, however, is that reported by Axenfeld and Busch.^^ ^here marked differences in the degree of bulging of the globe occurred accompanied at one time by pyrexia and swdling behind the angle of the jaw, at another, by fever, vomiting and pain in the affected eye. Ti.- 9 Painless Character of the Exophthalmos • 1 his feature of the disease was clearly recognized by LidelP in i860, but it remained for von Graefe'° (1864) to dignify the symptom by_ a general application, and to point o5t its value in differentiating between the closely invested tumours ot the optic nerve and those growths which were marked by a tendency to invade the deeper structures of the orbit
