In grave cases, by having an assistant skilled in the use of thesphygmomanometer make repeated estimations, the conditionof the blood-pressure may be kept constantly in mind. A fall inthe pressure below 90 mm. may in general be considered asignal to raise it by increasing the pressure in the pneumaticsuit.

In operations upon the neck, face, and mouth, the factorof haemorrhage, when the foregoing methods are fully em-ployed, is almost wholly eliminated. There are several proced-ures, however, that demand special consideration. The firstof these is the operation for excision of the Gasserian operation has justly acquired the distinction of being oneof the most difficult in surgery almost wholly on account ofthe factor of haemorrhage. In a personal experience in eigh-teen cases of excision of the ganglion I have had the oppor-tunity of comparing variou
