though frequent; debility flight; remiffion diftinguifhed 
by fweating or a cloud in the urine. 
3. Epanetus malignus, the malignant remittent; pulfe 
/mail, hurried, irregular; debility extreme; often with 
flgns of putrefcency. Of this there are four varieties. 
а. Autumnalis, the autumnal remittent: often with 
a ftrong tendency to affume the tertian or double tertian 
type. 
б. Flavus, the American yellow fever. 
y. Ardens, the burning, remittent, the Caufus (Kauc-of) 
of Hippocrates. 
S. Afthenicus, the highly-debilitating remittent of the 
fouth of Spain, Gombron, Breflaw, &c. 
3. Epanetus hedlica, hedlic fever: pulfe weak ; ftages 
of chillinefs, heat, and fweat, varioufly intermixed, and 
fometimes Angle; tire cold ftage exhaufting ; exacerba¬ 
tion chiefly in the evening : urine with a natant furfu- 
raceous feparation; countenance flightly fluflied or pale, 
funk, fallow, flirunk, and tremulous ; debility, but not 
decided proftration of ftrength; tongue whitifli; ema¬ 
ciation great, but not fudden; vertigo, or pain in the 
head ; pofition often fupine; anorexia, fometimes naufea 
and diarrhoea. 
Some writers have detailed accounts of an idiopathic 
Febris hedlica; but we believe it will generally be found 
that this is merely fymptomatic of a grave attack of Dyf. 
pepfia, under which article it has already been mentioned. 
It is for the molt part found as a fymptom in tabes ; and 
fometimes in phthifis, chlorofis, lues, and fcirrhous dif-' 
eafes of various organs. 
Genus IV. Enecia, [from y,huvs, perpetual.] Conti¬ 
nued fever. Generic charadiers—One feries of increafe 
and decreafe ; with a tendency to exacerbation and re¬ 
in iflion, for the molt part appearing twice every twenty- 
four hours. There are three fpecies, befldes varieties. 
1. Enecia cauma, inflammatory fever; the Synoche of 
Sauvages and Cullen. Heat greatly increafed ; pulfe 
quick, hard, and ftrong; urine red ; difturbance of the 
mind flight. Dr. Good has four varieties. 
a. Plethoricum. “Produced (fays Dr. Good) by the 
ftimulus of violent paflions, undue mufcular exercile, or 
heating foods, upon a plethoric habit; as alfo by a fup- 
preflion of accuftomed difcharges, as thofe of menftrua- 
ticn, habitual venefedtion, or perfpiration.” 
/ 3 . Biliofum: produced by the ftimulus of an undue 
fecretion or abforption of bile into the fanguineous 
fyftem. 
7. Pleuriticum : accompanied with a violent ftitch or 
pain in the pleura. 
S. Cephalalgicum : accompanied with great pain in the 
head, 
2. Enecia typhus: pulfe fmall, weak, and unequal; 
ufually frequent; great proftration of ftrength, and dif¬ 
turbance of the mental powers. Two varieties. 
a. Mitior, the nervous fever : with flight Ihiverings ; 
heavy vertiginous head-ach; oppreflion at the praecor- 
dia ; naufea ; fighing; defpondency ; coma or quiet de¬ 
lirium ; urine whey-like. 
( 3 . Gravior, putrid fever s countenance flirunk; eyes 
vague, fuffufed, and with a film of mucus; tongue chap¬ 
ped, dry, and very fordid ; complexion brownilh or flight 
pink; lips tremulous, fometimes muttering 5 pofition 
fupine, limbs extended ; refpiration frequent and tremu¬ 
lous ; little increafe of heat; bowels irregularly aftedled; 
relaxation of the fphindter redlum, £tc. ufual duration 
from fix to forty days. 
3. Enecia fynochus: compounded of cauma and ty¬ 
phus: in its commencement refembling the former; in 
its progrefs the latter. Here are four varieties. 
d. Sudatorius : carried off by a critical fweat in an 
early ftage of the difeafe. 
( 3 . Flavus: with yellownefs of the fkin, attended with 
a lenfe of burning heat. Nearly allied to Epanetus flavus, 
and E. ardens, varieties of E. malignus.

LOGY. 227 
7. Puerperarum, child-bed fever. See the article 
Parturition, vol. xviii. p. 674. 
S. Soporofus: accompanied with great drowfinefs, or 
ftupor. 
Order II. Plogotica, [from (pfcyo, I fet fire to, or 
burn.] Inflammations. 
Having already (fated in what mode the primary phe¬ 
nomena of inflammation were induced, and that the va¬ 
rieties of appearance this adtion exhibits were the refult 
of changes in the fecernent fyftem rather than in the red- 
blood veflels ; we (hall now proceed to confider the latter 
part of the pofition in queftion, i. e. what changes the 
fyftem of the white veflels undergoes in order to produce 
the varieties of inflammation. 
The principal varieties inflammation exhibits on its 
firft occurrence, are thofe of phlegmon, eryfipelas, 
and a mixture of both. In each, heat, pain, rednefs, 
and fwelling, are apparent ; but eryfipelas differs from 
phlegmon in this, that, while in the latter the degree 
of pain, rednefs, &c. gradually decreafing, clearly 
indicates, that the morbid change in the properties 
of veflels is moll intenfe in the middle of the injured 
part, and that the natural adtion is gradually reffored 
towards its circumference; in the former, heat, red¬ 
nefs, See. prefent an abrupt difcontinuance, one line 
having all the charadiers of inflammalion, but the next 
being perfectly pure from difeafe. The pain alfo is not 
of the fame kind, nor the fwelling fo great, in eryfipelas 
as in phlegmon. 
The remarks made while treating on inflammation in 
general, as to its mode of produdiion and its general ef- 
tedts on the conftitution, are molt particularly applicable 
to phlegmon. It remains, therefore, that we fliould now 
fpeak more particularly of eryfipelatous inflammation. 
From various circumftances it feems pretty clear, that 
eryfipelas is inflammation of the fkin ; but how it happens 
that the veflels of the fkin fhould differ fo materially 
from other parts in the phenomena they exhibit under 
the fame adtion, is one of the unfolved problems of our 
fcience ; nor, as far as we know, has its folution been 
ever attempted. According to Cullen, indeed, eryfipelas 
depends “ on a matter generated within the body, and 
thrown out, in confequence of fever, upon the furface of 
the body.” Mr. Pearfon reprefents it as the “ critical 
termination of another difeafe, fuch as obftrudted men- 
ftruation, quartan ague, fuppreffed fuppuration, fpaAno¬ 
dic and convulfive difeafes.” But thefe are merely vague 
conjedtures as to remote caufes, and have nothing to do 
with the queftion, why does inflammation in the cuta¬ 
neous ftrudture exhibit irregularity of fwelling, and burn¬ 
ing pain, &c. and why does inflammation in other parts 
manifeft the phenomena of phlegmon ? If it be faid, 
that this depends on the peculiar ftrudlure of the fkin, 
we mull fhow that thofe authors have been deceived who 
have fpoken of phlegmon attacking the fkin, and of ery¬ 
fipelas attacking deep-feated parts. It is a remarkable 
fadt, that thofe authors who have endeavoured to explain 
the phenomena of inflammation have for the raoft part 
confined their attention to phlegmon. It does not ac¬ 
cord wdth the purpofe of the prefent effay to fpeculate on 
this difficult lubjedt; but we (hall juft lay the fadts before 
our readers, whence they may draw their own concluiions. 
In the firft place, if eryfipelas be not folely confined to 
the fkin, it is in this ftrudlure that it is moft frequently 
met with, and moft fuddenly, extenfively, and clearly, 
manifefted. It is much influenced by and dependent on 
the Hate of the nervous fyftem, and of the primee vice, at¬ 
tacking for the moft part intemperate livers; and, when 
it attacks that part of the fkin in which the nervous fyf- 
tem is moft acute, it is developed with aflonifhing force 
and celerity. It is liable to be connedled with phlegmon, 
in which cafe we fhould fuppofe phlegmon to be the af- 
fedlion of deep-feated eryfipelas of the fuperficial parts of 
the body. It is intimately connedled with the ftate of
