CLASS I. i. i. 2. 07 IRRITATION. n 



al arterial ftrength cannot be determined by the touch, till the 

 part of the parcxyfm ceafes. This determination is fome- 

 times attended with difficulty ; as ftrong and weak are only com- 

 parative ae grees of the greater or Ids refiftance of the pulfation 

 of the artery to the compreilion of the finger. But the greater 

 or lefs frequency of the pulfations affords a collateral evidence 

 in thofe caies, where the degree of ftrength is not very diftin- 

 guifhable, which may arTift cur judgment concerning :c. Since 

 a moderatelv ilrong pulfe, when the patier.t is in a recumbent 

 pofture, and not hurried in mind, feldom exceeds 120 ilrokes in 

 a minute ; whereas a weak one often exceeds 130 in a recum- 

 bent poflure, and 150 in an eredl one, in thofe fevers, which 

 are termed nervous or putrid. See Seel. XII. i. 4. 



The increafcd frequency of the pulfatien. of the heart and ar- 

 teries, as it is occafioned either by excefs or defect of ftimiilus, or 

 of fenforial power, exifls both in the cold and hot fits of fever ; 

 but when the cold fit ceafes, and the pulfe becomes ftrong and 

 full as well as quick, in confequence of the increafed irritability 

 ,of the heart and arteries, it conftitutes the irritative fever, or fy- 

 nocha. It is attended with confiderable heat during the parox- 

 yfm, and generally terminates in a quarter of a lunation, without 

 anydifturbance of the faculties of the mind. SeeClafsIV. i. 1.8. 



M. M. Venefetlion. Emetics. Cathartics. Cool the patient 

 in the hot fit, and warm him in the cold one. Reft. Torp, 



2. Ebrittas. Drunkennefs. By the ftimulus of wine or opi- 

 um the whole arterial fyftem, as well as every other part of the 

 moving fyftem, is excited into increafed action. All thefe fe~ 

 cretions, and with them the production of fenforial power itfelf 

 in tlvj brain, feem to be for a time increafed, with an additional 

 quantity of heat, and of pleafurable fenfation. See Seel:. XXI. 

 on this kibjecl. This explains, why at the commencement of 

 the warm paroxyfm of fome fevers the patient is in greater fpir- 

 its, or vivacity ; becaufe, as in drunkennefs, the irritative motions 

 are all increafed, and a greater production of fenfation is the con- 

 fequence, which, when in a certain degree, is pleafurable, as in 

 the diurnal fever of weak people. Sect. XXXVI. 3.1. 



3. Hcemorrbagia arteriofa. Arterial haemorrhage. Bleeding 

 with a quick, ftrong, and full pulfe. The hemorrhages from 

 the lungs, and from the nofe, are the molt frequent of thefe -, but 

 it fometimes happens, that a fmall artery but half.divided, or the 

 puncture of a leech, will continue to bleed pertinacioufly. 



M. M. Venefelion. Cathartic with calomel. Divide the 

 wounded artery. Bind fponge on the puncture. If coffee or 

 , internally ? If air, with leis oxygen ?
