ERUPTIVE FEVERS. 187 



stances of this kind ; yet from the frequent accounts of authors, 

 we may suppose that they occur. 



" I have only to observe, that there is one translation which 

 has been very much noticed, viz. the translation from the face 

 to the internal parts of the brain. So far as I can observe, this 

 has been improperly called a translation ; it is no more to me 

 than a communication, which may be readily expected from the 

 connexion between the external and internal carotids. I con- 

 clude so from hence, that in a very great number of cases where 

 I have seen it taking place, the two affections constantly sub- 

 sisted at the same time ; that is to say, the brain was affected 

 by the symptoms of delirium or stupor, but at the same time the 

 Erysipelas on the face continued as full and considerable as it 

 was before. It is only on this account that Erysipelas on the 

 face is a dangerous disease, while very little danger attends it 

 while affecting the extremities." 



DC CIV. When the fatal event does not take place, the in- 

 flammation, after having affected a part, commonly the whole of 

 the face, and perhaps the other external parts of the head, ceases. 

 With the inflammation, the fever also ceases ; and, without any 

 evident crisis, the patient returns to his ordinary state of health. 



DCCV. This disease is not commonly contagious ; but as it 

 may arise from an acrid matter externally applied, so it is pos- 

 sible that the disease may sometimes be communicated from one 

 person to another. 



Persons who have once laboured under this disease are liable 

 to returns of it. 



DCCVI. The event of this disease may be foreseen from the 

 state of the symptoms which denote more or less affection of the 

 brain. If neither delirum nor coma come on, the disease is sel- 

 dom attended with any danger ; but when these symptoms ap- 

 pear early in the desease, and are in a considerable degree, the 

 utmost danger is to be apprehended. 



DCCVII. As this disease often arises in the part, at the same 

 time with the coming on of the pyrexia ; as I have known it, 

 with all its symptoms, arise from an acrimony applied to the 

 part ; as it is commonly attended with a full, and frequently a 

 hard pulse ; as the blood drawn in this disease shows the same 

 crust upon its surface that appears in the phlegmasiae; and,
