the diurnal is still more protracted, and in some cases passes into

phthisis. The septan is protracted, but not fatal; the nonan more

protracted, and not fatal. The true tertian comes quickly to a crisis,

and is not fatal; but the quintan is the worst of all, for it proves

fatal when it precedes an attack of phthisis, and when it supervenes

on persons who are already consumptive. There are peculiar modes,

and constitutions, and paroxysms, in every one of these fevers; for

example,- the continual, in some cases at the very commencement,

grows, as it were, and attains its full strength, and rises to its

most dangerous pitch, but is diminished about and at the crisis; in

others it begins gentle and suppressed, but gains ground and is

exacerbated every day, and bursts forth with all its heat about and at

the crisis; while in others, again, it commences mildly, increases,

and is exacerbated until it reaches its acme, and then remits until at

and about the crisis. These varieties occur in every fever, and in

every disease. From these observations one must regulate the regimen

accordingly. There are many other important symptoms allied to

these, part of which have been already noticed, and part will be

described afterwards, from a consideration of which one may judge, and

decided in each case, whether the disease be acute, acute, and whether

it will end in death or recovery; or whether it will be protracted,

and will end in death or recovery; and in what cases food is to be

given, and in what not; and when and to what amount, and what

particular kind of food is to be administered.

3. Those diseases which have their paroxysms on even days have their

crises on even days; and those which have their paroxysms on uneven

days have their crises on uneven days. The first period of those which

have the crisis on even days, is the 4th, 6th, 8th, 10th, 14th,

20th, 30th, 40th, 60th, 80th, 100th; and the first period of those

which have their crises on uneven days, is the 1st, 3d, 5th, 7th, 9th,

11th, 17th, 21th, 27th, 31st. It should be known, that if the crisis

take place on any other day than on those described, it indicates that
