Such generalities are indeed true: none the less they descend from them to certain particular characteristics, unless they would persuade us that climate and season are to be taken into consideration by those in health but not by the sick, the very persons in whom all such observance is by so much the more necessary, the more that their weakness is liable to all attacks. Nay, even in the same patient, the particular characteristics of a disease are very various, and those who have been treated for a time in vain by the ordinary remedies have been often restored by contrary ones.
