hemiplegia.. Still more, there is no doubt that in some of the eases in which there has been a paralysis on the opposite side to that of a cerebral lesion, with another lesion in the side of the cerebellum corresponding with the paralysis, this last lesion was such as to produce a pressure on the pons Varolii.So that we come to this state of things: that .generallywhen a pressure upon one-half of the pons Varolii.by blood effused in the cerebellum exists alone, it .causesa crossed paralysis ; while it seems not to cause a

which it may be supposed to possess must be determined by the future history of the patient.The operation of removing the arm at the shoulder-joint was first performed by the elder Morand, and afterwards by Le Dran, who describes very particularly the manner in which he operated.Various modes have since been suggested and practised.That by a flap of the deltoid is, perhaps, the favourite and the easiest.It has, however, always appeared to me, when I have witnessed this mode on the living and in rehearsing it on the dead subject, that the axillary flap was too thin, irregular, and not a good companion for its fellow; so that I determined upon the following, which gives a most complete line of union, and accurate adjustment of equalsized flaps, with the smallest amount of wound.The patient recumbent, and fully under the influence of chloroform, Mr. Gay commanded the subclavian artery.A short, stout-bladed amputating knife was thrust into the joint immediately below the acromion, and carried down the humerus in a straight line (dividing the deltoid into two equal halves) until it reached a point even with the posterior fold of the axilla, into which it was carried, and a posterior flap thus marked out raised.An anterior flap was formed in like manner by an incision starting immediately within the front axillary fold, and falling into the base of the first.The knife was then passed horizontally into the joint, separating the biceps tendon and other connexions with the head of the humerus.Mr. Adams, who held the limb, then thrusting the head of the bone outwards, the amputation was completed by division of the vessels and nerves and other soft parts consti- tuting the floor of the axilla, Mr. Allingham securing the artery in a grip by closely following the knife with his fingers as it completed the separation.The axillary, circumflex, and other muscular arteries were then secured, and the flaps ap- proximated.
