i<5 4 DISEASES CLASS II. i. 2.1, 



flammatory fever. Phlegmafia. A flrong full pulfe, with in- 

 flammation of the coats of the arteries, conftitutes this difeafe. 

 Jt originates from fome topical inflammation, whieh, if the fever 

 is not fubdued, terminates in fuppuration ; and differs from ir- 

 ritative fever in refpeft to the painful fenfation which accompa- 

 nies it. For as pleafurable fenfation i* the caufe of the growth 

 of the new veflels, and diftention of the old ones, in the natural 

 enlargement of the body during our infancy ; fo a painful fenfa- 

 tion is the caufe of the unnatural production of new veffels, and 

 enlargement of old ones in inflammatory difeafes. 



When matter is thus formed in any internal vifcus, or in 

 the cellular membrane, as in the lungs or liver; fo long as this 

 abfcefs remains without admiffion of air, this inflammatory fever 

 is Jiable to continue, recieving only temporary relief by bleeding 

 or emetics, or cathartics , till the patient, after a month, or two, 

 or three, expires. But, if air be admitted to thefe internal ab- 

 fcefles, this kind of fever is changed into a heftic fever in a fin- 

 gle day. It alfo fometimes happens, that when the abfcefs re- 

 mains unopened to the air, if the matter has become putrid, hec- 

 tic fever iupervenes, with colliquative fweats, or diarrhoea ; the 

 matter in both cafes is fometimes abforbed, and the fides of the 

 abfcefs grow together again without an external aperture. See 

 ClafsII. 1.4. i. and 2. Another termination of inflammation 

 is in gangrene, but this belongs to the inflammation of the ex- 

 ternal ikin *, as the production of purulent matter belongs to in- 

 flammation of the internal or mucous membranes. Thus when 

 the external fkin is the feat of inflammation, as in erythema, or 

 eryfipelas, and produces fenfitive irritated fever, no collection of 

 purulent matter can be formed ; but a material oozes out, and 

 lies upon the furface, like that in the confluent fmall-pox, and 

 the cuticle at length peels off, or gangrene fupervenes. It mutt 

 be noted, thnt thefe kinds of inflammation can exitl together ; 

 and fome parts of the cellular membrane may fuppurate at the 

 fame time that the external Ikin is affected with erythema, or 

 eryfipehs. 



M. M. Venefeclion. Cathartics. Diluents. Cool air. 

 Torpentia. Cold bath ? See Sett. XII. 6. 



The increafed arterial a6Hon in this fenfitive irritated fever is 

 not fimply owing to the increafed irritability of the arterial fyf- 

 fem, or to the ftimuius of the diftention of the veiTels, but aifo 

 to the increafed acrimony or pungency of the blood ; which 

 has now fo far changed its nature as to become more fluid, 

 rnore denfe, and to be loaded with coagulable lymph. Hence 

 it becomes neceffary not only to leflen the quantity of blood 

 by venefetlion and by cathartics, but alfo to dilute its acrimo- 

 ny*
