depends on the condition of the patient. When slowly executed, this series of movements is so easy and gentle that they may be performed by women in pregnancy and the puerperium, and by invalids in general. Note I.—Properly instructed and careful lay persons are also able to give the necessary assistance and support in this exercise. Or two expectant mothers in a hospital or nursing home may help one another. This help is most comfortable if the couch or table is comparatively high, as in Fig. 40. Note 2.—The gymnastic instructress or assistant must not press the large blood vessels of the thigh with her finger tips, and should even avoid pressure on the smaller veins. (b) The completely passive nature of this exercise (as described under (a) ) is changed into resistance to pressure if the instructress presses the patient's thigh with her hand so that some exertion is necessary in order to raise the knee. Similarly, a certain degree of pressure is possible with the other hand against the patient's foot. Of course, the amount of exertion may be modified to any degree. The instructress must be on guard against undue strain of the diaphragm, and regular breathing is, therefore, essential during this exercise. (14) Knee Rotation (Fig. 31). Recumbent posture as in preceding exercise ; and as in 13, the instructress holds the patient's foot and, with the other hand, her knee. The instructress rotates the patient's knee outwards, at first slightly, then in wider circles. Practise alternately left and right. (15) Lifting and Lowering the Pelvis (Fig. 32). Recumbent posture, with raised knees. The instructress supports the patient's body by placing her hands beneath loins and buttocks. The patient then endeavours slowly to raise her pelvis, aided by the instructress ; thus there is a combined movement, the patient taking part without over- exerting herself. Having lifted her pelvis so far as possible from the couch or table, she should slowly lower it and return to the initial posture, On no account should the pelvis be jerked down,
