540 PRACTICE OF PHYSIC. 



cold, and was seized with the shivering and hot fit, which did not 

 go beyond the shoulder ; and we have two instances in the Me- 

 dical Essays where one leg and thigh were affected, and another 

 instance, which is more ambiguous indeed, in which sometimes 

 the arms, and sometimes the legs, and sometimes both together, 

 were affected with the cold fit. I myself have seen it confined 

 to the lower extremities ; and Senac furnishes us with several 

 examples to the same purpose. 



" The other cases are different from this ; they are merely a 

 pain attacking only one particular part, and that pain occurs 

 with the circumstance of a cold or hot fit ; but it returns re- 

 gularly at a certain hour, subsists for a certain number of hours, 

 and is cured, like the genuine intermittents, by the use of the 

 Peruvian bark. The most noted instance is the Quotidiana 

 cephalalgica, or the Hemicrania, which is so frequently quotidian. 

 It affects one side of the head only, commonly near to the eye, 

 and sometimes takes in the orbit of the eye, and so is attended 

 with ophthalmia. 



" The chief varieties of the Quotidianae comitatoe, are the 

 Quotidiana ischiadica, the Quotidiana nephralgica, and the 

 Quotidiana epileptica. There are also the Quotidianae vcsper- 

 tinae vel symptomaticae, such as the hysterica, catarrhalis, and 

 stranguriosa, which are manifestly owing to the presence of an- 

 other disease, and are to be considered as symptomatic of it only . 



" II. The only Remittent quotidian is the Amphimerina of 

 Sauvages and Linnaeus. I admit one species only, the Amphi- 

 merina latica ; and even with regard to it I am doubtful ; for 

 if it is doubtful if even the intermittent quotidian be a genuine 

 species, it is still more doubtful with respect to the Amphimerina." 



CHAP. IV. OF THE REMOTE CAUSES OF FEVER. 



LXXVI. As fever has been held to consist chiefly in an in- 

 creased action of the heart and arteries, physicians have sup- 

 posed its remote causes to be certain direct stimulants fitted to 

 produce this increased action. In many cases, however, there 

 is no evidence of such stimulants being applied ; and, in those 

 in which they are applied, they either produce only a tempo-
