516 PRACTICE OF PHYSIC. 



in applying the doctrine to particular cases. It applies tolera- 

 bly well to explain the different states of intermittents, as they 

 are more purely such, or as they approach more and more to 

 the continued form. But several difficulties still remain with 

 respect to many circumstances of intermittents ; and more still 

 with respect to the difference of those continued fevers which 

 we have distinguished in our Nosology as different from inter- 

 mittents, and as more especially entitled to the appellation ef 

 Continued (See Syn. Nos. Meth. cl. i. ord. i. sect. 2.), and 

 explained more fully above. 



" With respect to the division into intermittent and continu- 

 ed fevers, a great difficulty still remains. Under the title of 

 Intermittents, I comprehend what other systems call Remittents. 

 I am led to this conclusion by these considerations -.first, 

 in the same seasons and climates, we generally find the In- 

 termittents and the Remittents epidemic at the same time : 

 we never find in any case, except in a few springs of northern 

 climates, intermittents without remittents ; at the same time, 

 we can observe that the remote causes of each are truly the 

 same, viz. Marsh Effluvia ;-~secondly, the remittents very 

 generally arise out of the intermittents, and vice versa ; 

 thirdly, the remittents, when they appear, very universally 

 observe the periods of the intermittents ; and, fourthly, they 

 are cured by the same remedy, viz. the Peruvian bark : which, 

 if I mistake not, never is a remedy to the same extent in conti- 

 nued fevers. 



" Now, from all these considerations, I would infer that the 

 intermittents and remittents are the same disease; and although 

 this is discussing a seemingly trifling question in Nosology, this 

 and every other such question is important in Pathology, and 

 deserves to be settled." 



LXV. From the view given (LXII. and LXIII.) of the 

 causes of the protraction of paroxysms, and therefore of the form 

 of continued fevers, strictly so called, it seems probable, that 

 the remote causes of these operate by occasioning either a phlo- 

 gistic diathesis, or a weaker reaction ; for we can observe, that 

 the most obvious difference of continued fevers depends upon 

 the prevalence of one or other of these estates. 



LXVI. Continued fevers have been accounted of great di-
