Dr. Mac Culloch on Fevers, 51 



diseases are, rheumatism under various forms, including, as 

 a very marked variety, that of the face and head, and oph- 

 thalmia ; that disease already known by the term rheumatism 

 of the eye, but which, in our author's hands, has put on a 

 most important form, since it is proved to be the most common 

 variety of this disease that exists, and also to have been as 

 much mistaken as it has been improperly treated. 



Next follows a division of neuralgise from injuries, such 

 as wounds, tumours, ulcers, &c. ; while we need not specify 

 the varieties enumerated, as they are mere examples of facts, 

 and as this kind may obviously occur any where. For the 

 division which succeeds, entitled neuralgic affections of 

 glands, we must look entirely to Dr.M., of whose theory the 

 fact forms a portion, while the examples enumerated have 

 occurred in the kidneys, producing diabetes, in the lacrymal 

 and salivary glands, producing similarly augmented secre- 

 tion, and as it appears probable, in the intestinal mucous 

 membrane, and in that of the trachea and nose, generating 

 diarrhoea and catarrh. 



Lastly, follows a table of the consequences of neuralgia. 

 These consequences, we must premise by saying, are asserted 

 to occur chiefly when a neuralgia has been of long dura- 

 tion, as also when blood-letting or other debilitating prac- 

 tices have been adopted ; yet in some local instances, they 

 follow very speedily, and even attack as the substitutes of the 

 painful disease. The enumerated ones are, mania, fatuity, 

 palsy, and nervous undefinable disorders, as of a general 

 nature ; and as partial, amaurosis, contraction of the iris, 

 and opacity of the cornea as a sequel of the ophthalmia, with 

 a few other particulars as to the teeth, into which we need not 

 here inquire. 



Such then is this list which, in its tabular form, together 

 with that alloted to marsh fever, conveys an idea not less 

 clear than it is novel, of the extent as well as of the import- 

 ance of these generic diseases. As to the neuralgia, it is 

 almost superfluous to say, that, with the exception of a very 

 few cases, and those also of somewhat recent occurrence, the 

 term, and not less the disease, had been supposed confined to 

 the well known nerves of the face, and that all the previous 

 essays on it were equally limited ; being, if we may use this 

 term in its inofi*ensive sense, of an empirical as well as a 

 partial nature. Not the least suspicion seems to have been 

 entertained by any previous writer, that this disorder was 

 generic, not local and limited ; nor was it suspected that 

 toothagh, sciatica, and the other painful affections of i^eryea
