20 DISEASES Class I. i. 2. 14. 



In fome conflhutions the perfpirable matter of the lungs ac- 

 quires a difagreeable odour ; in others the axilla, and in others 

 the feet, emit difguftful effluvia ; like the fecretions of thofe 

 glands, which have been called odoriferse *, as thofe, which con- 

 tain the caftor in the beaver, and thofe within the rectum of 

 clogs, the mucus of which has been fuppofed to guard them 

 again it the great coftivenefs, which they are liable to in hot 

 fummers ; and which has been thought to occafion canine mad- 

 nefs, but which, n ^e their white excrement, is more probably 

 owing to the deficient fecretion of bile. Whether thefe odorif- 

 erous particles attend the perfpirable matter in confequence of 

 the increafed action of the capillary glands, and properly be 

 called excrementitious - T that is, whether any thing is elimina- 

 ted, which could be hurtful if retained ; or whether they may 

 only contain fome of the eilential oil of the animal ; like the 

 fmell, which adheres to one's hand on ftroking the hides of 

 fome dogs ; or like the effluvia, which is left upon the ground, 

 from the feet of men and other creatures ; and is perceptible by 

 the nicer organs of the dogs, which hunt them, may admit of 

 doubt. 



Add to t&js, that fome parts of the {kin are liable to more 

 profufe perfpiration than other parts without poffefling any fetid 

 fcent, as the fkin of the face, on any more violent exercife. This 

 feems to have been obferved very early in the hi (lory of man- 

 kind, as it was find, that our firft parents mould earn their bread 

 by the fweat of their brow. Why this circumftance does not 

 attend other animals is a curious inquiry. Mankind foon learn- 

 ed to cover their bodies, except their faces, with clothes •, when 



e face, by being more frequently expofed to greater variations 



heat and cold, acquired greater irritability, or fenfibility, or 



bciabilityj and thus has become more excitable into greater ac- 

 tion by the Uimulus of exercife, or by that of food, or by the va- 



!us infeclion, than, other parts of the fkin, as fpoken of in 

 Clair, IV. 1. 2. 12*, which alfo appears by its fympathy with 

 difeafes of the liver or ftomacn by fenfitive aflbciations, as in the 

 gntta rofea. From all thefe analogous fa els the profufe fweat, 

 which exudes from the face on exercife, does not appear to be 

 an excrementitious fluid, but fimply the confequence of more 

 violent adlion of the cutaneous or perfpirative glands. 



M. M. Wafh the parts twice a day with lo^-p and water; 



ith lime water ; cover the feci with oiled filk focks, which 



mil be vyai . and morning. Coyer them with charcoal 



recently made red hot, and beaten into fine powder and fifted, 



as foon as cold, and kept well corked in a bottle, to be wafhed 



off
