The knife should be held like a pen and moved by the fingers and thumb, not by the wrist and elbow, and sometimes, as I have seen, by the shoulder. The student should practice its use also with the left hand; such an education will be of great advan- tage, especially in surgical operations. In the dissection of a part, it is a good rule not to turn off more of the skin than is necessary for the exposure of the part, and always to replace it again during the interval of dissection. Generally I think it better to turn off the structures in the order of superposition; as the skin, superficial fascia, deep fascia, &c. In dissecting a muscle the parts should be made tense, which is done by blocks properly placed under the subject. The cellular membrane which imme- diately invests the muscle, must be kept extended by the hand or forceps, and the edge of the knife carried steadily in the direction of its fibres. This rule admits of no ex- ceptions, and should never be lost sight of by the student. There are many operations which may be done on the
