    from the peculiarity of the case, to employ these regions, prepara- tion should be made to ward off the dangers to which the patient is inevitably exposed. When, for example, we are obliged to trephine through the frontal sinus, recollecting the hazard we run of wounding the dura mater, we should resort to the ingenious method of Sir C. Bell, who first opens the anterior wall with a large trephine, and then introducing a smaller one, and depressing the handle so as to act smoothly upon the inner table, completes the operation without wounding the membrane. Except in children, or unusual confor- mations, where the tables ace in contact, this process essentially wards off the danger. Again, where a fracture occurs at or near the anterior and inferior angle of the parietal bone, and it becomes necessary to trephine, we must recollect that the middle artery of the dura mater runs in a groove or canal just along this region ; should it be divided it may be tied, as was done by Dorsey, others and myself, or it may be plugged with a piece of wood or wax, as advised by Physick; or it may be cauterized, as recommended by Larry; or it may be compressed with lint, as was done by myself in the case reported by Dr. Squibb. Also, if obliged to trephine over the sagittal suture, or over the junction of the sinuses, at the occipital region, we must recollect the danger of wounding the longitudinal sinus, or some of these ves- sels, in which event our only remedy is compression, and fortu- nately this is, for the most part, sufficient. . Lastly, if obliged to operate in the temporal fossa, we must an- ticipate bleeding from the numerous arteries which are assembled in this region, and also an extensive dissection through the belly of the temporal muscle.—T. D. M.] OPERATIONS ON THE EYE. I shall now say something about operations on the appendages of the eye. I believe that diseases of the eye have already been fully discussed in the previous divisions of this course of lectures; but there are some diseases of the parts around, and some operations required on the parts connected with the organ, which are deserv- ing of notice and attention. AFFECTIONS OF THE LID. In the first place, then, you will have now and then forming, in the upper lid especially, small tumours. I do not mean to tell you
