t of the common rules of hygiene.' It is Dr
Burgess's theory, therefore, that when change is necessary, a
modification of the patient's own climate--that is to say, change of
air in the same climate--is more in accordance with the laws of
nature, and more likely to effect good, than a violent transition to
warmer countries.

With regard to the curability of this disease, there is now, we
believe, no doubt of the fact, although, unfortunately the process has
not yet come completely into the hands of the physician. That a cure
has frequently taken place, somehow or other, even in advanced stages
of pulmonary consumption, has been demonstrated by _post-mortem_
examinations; but nature herself seems, in these cases, to have been
her own doctor, for no mode of treatment of general applicability has
been discovered. Some think that the progress of tubercles may be
arrested in the first stage--others, that nothing can be effected till
the second. Some resort to the water-cure--others, to the still more
marvellous Spanish baths of Panticosa; and others, again, swear by
cod-liver oil. As to the last remedy, our author quotes the statements
of Dr Williams, 'that the pure fresh oil from the liver of the cod is
more beneficial in the treatment of pulmonary consumption than any
agent, medicinal, dietetic, or regimenal, that has yet been employed.
Out of 234 cases carefully recorded, the oil disagreed, and was
discontinued, in only 9 instances. In 19, although taken, it appeared
to do no good; whilst in the larger proportion of 206 out of 234, its
use was followed by marked and unequivocal improvement--this
improvement varying in degree in different cases, from a temporary
retardation of the progress of the disease, and a mitigation of
distressing symptoms, up to a more or less complete restoration to
apparent health. The most numerous examples of decided and lasting
improvement, amounting to nearly 100, have occurred in patients in the
second stage of the disease, in which the tuberculous deposits begin
to undergo the process of softening. The most striking instance of the
beneficial operation of cod-liver oil in phthisis, is to be found in
cases in the _third_ stage--even those far advanced, where consumption
has not only excavated the lungs, but is rapidly wasting the whole
body with copious purulent expectoration, hectic, night-sweats,
colliquative diarrhoea, and other elements of that destructive process
by which, in a few week
