HOVEL BRAIN-BUILDING.

The wonderful effect upon She brain produced by systematic handculture,, more particularly in the matter of two-handed writing, is the subject of an interesting statement by Dr Manfred Fraenkel, of Berlin. At least 951s per cent of all people, Dr fraenkel points out, are righthanded, and accordingly the location for the pictures of the recollection is the left brain, which, in consequence of the crossing of the nerves in the spinal marow, has to control the right i hand. "As everything is subject to the left brain (the right-hand provider), all our thoughts, feelings, actions, writing, and motions the right brain doe 3 not influence it at all. Examinations on patient 3 whose right hand was paralysed by a* fit of apoplexy, and who have to rely only on the right hand half of the brain, have prove J that the persons, suddenly deprived of the use of the tongue and of all the movements of the right side, are not capable of doing anything with the left hand, which is now without a guide. "During the course of my examinations I have found a possibility of helping these poor creatures to new signs of life.- and that simply by exercising the left hand. I have coma to the conclusion that normal persons likewise will succeed in making the left hand equal to the right one by practising the left ha'rid and by developing to higher perfection the fight hemisphere of triebbrainn n "We succeeded with a patient, paralysed on the right side, by dit.t of systematic writing with the left hand. He regained his power of speach, which he had lost. His ■ linguistic capacity of the right side, although existing, but not cultivated before, had been awakened to full activity. Another atroke, affecting the right side, again deprived him of the slight flexibility of the right hand which he had just regained, ' but—as a oroof of my principles being right—his speech remained."
