Withthe instrument mentioned I was able to remove in several fragments mostof the anterior lobe, and practically the whole of the posterior lobe remove the entire pituitary body I had a special instrument made:this consists of a lower blade terminating in a blunt hook in which thestalk of the pituitary is caught; the upper blade, which is formed like SG Blair Bell a chisel but is blunt, can be pushed in, so as to cut through the stalkcaught in the hook (fig. 12). The lower attachments of the pituitary werealways first separated with a fine blunt Watson-Cheyne dissector (fig. 13),before the stalk was cut through; after this the pituitary could be liftedout with a pair of bent forceps. This freeing of the lower attachments oftlie pituitary was found advisable in all operations except those in which ?a. ••_i«*iW Fig, 9.—View of the field of operation at the stage when the pituitary is first exposed. Thecircle of liglit from the head lamp is seen in the centre of the field. (Drawing.) the stalk was separated or clamped, or in which an artificial tumourwas introduced. The operation was completed by the sewing of the temporal muscles inplace, and the closing of the skin incision. Alarming haemorrhage sometimes occurred during the operation,especially in the older animals, but in all except one case this wascontrolled without difficulty; and probably there was a little careless-ness in the case that was lost, for one had got used to checking thehaemorrhage easily with wool plugs, and had come to regard it as of littleconsequence. Nevertheless, the operation was found to be much lessformidable than the previous descriptions of it led us to expect. Gushing KxpLriiiuUtal itLmti()iis oii tin- Iituiiary 87 stiit
