EMACIATIONS. 565 



rent outlets ; and Sauvages has properly enumerated the fol- 

 lowing species, which we have put as synonymes under the title 

 of Atrophia inanitorum ; as, Tabes nutrlcum^ sp. 4. Atro- 

 phia nutricum, sp. 5. Atrophia a leucorrhcea, sp. 4. Atro- 

 phia ab alvi fluwu, sp. 6. Atrophia a ptyalumo, sp. 7- '> and 

 lastly, the Tabes a sangmfluoou ; which, it is to be observed, 

 may arise not only from spontaneous haemorrhagies or accidental 

 wounds, but also from blood-letting in too large a quantity, 

 and too frequently repeated. 



Upon this subject it seems proper to observe, that a meagre 

 habit of body frequently depends upon a full perspiration being 

 constantly kept up, though at the same time a large quantity of 

 nutritious aliment is regularly taken in. 



MDCIX. Besides this deficiency of fluids from evacuations 

 by which they are carried entirely out of the body, there may 

 be a deficiency of fluid and emaciation in a considerable part of 

 the body, by the fluids being drawn into one part, or collected 

 into one cavity ; and of this we have an instance in the Tabes 

 a hydrope, Sauv. sp. 5. 



MDCX. In the Methodical Nosology, among the other 

 synonymes of the Atrophia inanitorum, I have set down the 

 Tabes dorsalis ; but whether properly or not, I at present 

 very much doubt. In the evacuation considered as the cause 

 of this tabes, as the quantity evacuated is never so great as to 

 account for a general deficiency of fluids in the body, we must 

 seek for another explanation of it. And whether the effects of 

 the evacuation may be accounted for, either from the quality of 

 the fluid evacuated, or from the singularly enervating pleasure at- 

 tending the evacuation, or from the evacuations taking off the 

 tension of parts, the tension of which has a singular power 

 in supporting the tension and vigour of the whole body, I can- 

 not positively determine ; but I apprehend that upon one or 

 other of these suppositions the emaciation attending the Tabes . 

 dorsalis must be accounted for ; and, therefore, that it is to be 

 considered as an instance of the Atrophia debilium, rather than 

 of the Atrophia inanitorum. 



MDCXI. A fifth cause of a deficiency of fluids and of ema- 

 ciations in the whole or in a particular part of the body, may 

 be the concretion of the small vessels, either not admitting of
