healthy, and have good abilities, yet they
differ as much from each other in mental cast as any one of my
family differs from another."

(4.) "Very dissimilar in body and mind: the one is quiet, retiring,
and slow but sure; good-tempered, but disposed to be sulky when
provoked;--the other is quick, vivacious, forward, acquiring easily
and forgetting soon; quick-tempered and choleric, but quickly
forgiving and forgetting. They have been educated together and never
separated."

(5.) "They were never alike either in body or mind, and their
dissimilarity increases daily. The external influences have been
identical; they have never been separated."

(6.) "The two sisters are very different in ability and disposition.
The one is retiring, but firm and determined; she has no taste for
music or drawing. The other is of an active, excitable temperament:
she displays an unusual amount of quickness and talent, and is
passionately fond of music and drawing. From infancy, they have been
rarely separated even at school, and as children visiting their
friends, they always went together."

(7.) "They have been treated exactly alike both were brought up by
hand; they have been under the same nurse and governess from their
birth, and they are very fond of each other. Their increasing
dissimilarity must be ascribed to a natural difference of mind and
character, as there has been nothing in their treatment to account
for it."

(8.) "They are as different as possible. [A minute and unsparing
analysis of the characters of the two twins is given by their father,
most instructive to read, but impossible to publish without the
certainty of wounding the feelings of one of the twins, if these
pages should chance to fall under his eyes.] They were brought up
entirely by hand, that is, on cow's milk, and treated by one nurse
in precisely the same manner."

(9.) "The home-training and influence were precisely the same, and
therefore I consider the dissimilarity to be accounted for almost
entirely by innate disposition and by causes over which we have no
control."

(10.) "This case is, I should think, somewhat remarkable for
dissimilarity in physique as well as for strong contrast in character.
They have been unlike in body and mind throughout their lives. Both
were reared in a country house, and both were at the same schools
till _aet._ 16."

(11.) "Singularly unlike in body and mind from babyhood; in looks,
dispositions, and tastes t
