during the last two years;
and that, too, within a very limited range. Nor have we by any means
exhausted the list. Quite recently we had the opportunity of marking how
the evil becomes hereditary: the case being that of a lady of robust
parentage, whose system was so injured by the _regime_ of a Scotch
boarding-school, where she was under-fed and over-worked, that she
invariably suffers from vertigo on rising in the morning; and whose
children, inheriting this enfeebled brain, are several of them unable to
bear even a moderate amount of study without headache or giddiness. At
the present time we have daily under our eyes, a young lady whose system
has been damaged for life by the college-course through which she has
passed. Taxed as she was to such an extent that she had no energy left
for exercise, she is, now that she has finished her education, a
constant complainant. Appetite small and very capricious, mostly
refusing meat; extremities perpetually cold, even when the weather is
warm; a feebleness which forbids anything but the slowest walking, and
that only for a short time; palpitation on going upstairs; greatly
impaired vision--these, joined with checked growth and lax tissue, are
among the results entailed. And to her case we may add that of her
friend and fellow-student; who is similarly weak; who is liable to faint
even under the excitement of a quiet party of friends; and who has at
length been obliged by her medical attendant to desist from study
entirely.

If injuries so conspicuous are thus frequent, how very general must be
the smaller, and inconspicuous injuries! To one case where positive
illness is traceable to over-application, there are probably at least
half-a-dozen cases where the evil is unobtrusive and slowly
accumulating--cases where there is frequent derangement of the
functions, attributed to this or that special cause, or to
constitutional delicacy; cases where there is retardation and premature
arrest of bodily growth; cases where a latent tendency to consumption is
brought out and established; cases where a predisposition is given to
that now common cerebral disorder brought on by the labour of adult
life. How commonly health is thus undermined, will be clear to all who,
after noting the frequent ailments of hard-worked professional and
mercantile men, will reflect on the much worse effects which undue
application must produce on the undeveloped systems of children. The
young can bear neit
