brain, and as to which side of the brain is likely to be affected 
when Aphasia occurs in left-handed persons. 
Mr ANNINGSON questioned whether lopsidedness was really 
a part of right-handedness, forasmuch as the left hand is em- 
ployed not only as a helpmate to the right, but for many 
purposes in which the right hand is less efficacious. 
Mr Carver thought the observations in the nursery shewed 
that right-handedness was acquired rather than innate; children 
having commonly a propensity to use the left hand, which it 
required some difficulty to counteract. 
Professor Humpury stated that the paper, which was one of 
much learning and interest, as well as suggestive, had been 
consigned to him for publication in the next number of the 
Journal of Anatomy and Physiology. In reply to various 
questions which had been asked, he said he believed an advan- 
tage gained by preferential use of the right hand, was a greater 
aptness and precision of movement requisite for delicate mani- 
pulations than could have been attained had both limbs been 
equally employed. Left-handed persons, being prevented by 
social custom from concentrating their attention on the left 
hand and being compelled to give a frequent preference to the 
right, are at some disadvantage in this respect. He could see 
no anatomical reason for the preference of the right limb, the 
slight advantage in circulation to the right arm through the 
innominate artery and vein applying, in nearly equal degree, to 
the right side of the brain. He agreed with Mr Carver that 
right-handedness was much a matter of education, and followed 
from the multifarious single-handed offices which are associated 
with the higher mental endowments,
