Abstract

IN answer to Mr. Meyer's letter on this subject, I can only say that the question of the dependence of Left-handedness on abnormality of the subclavian artery cannot be settled by the authority of even so eminent an anatomist as Professor Hyrtl, when it is adduced against the facts I mentioned in my last note. That there have been cases like that quoted from Dr. Buchanan of transposition of viscera and left-handedness occurring in the same individual, and that they will be observed again, I do not doubt. Otherwise the conclusion would be that such abnormalities prevent left-handedness, which no one pretends. What I venture to think the cases already on record prove is, that the one condition has no relation to the other in either causing or preventing it.
