334 OF GLANDS AND MEMBRANES. SECT. XXV? s. 



the white of egg, which was difcharged by ftool, 

 did not coagulate, though I evaporated it to one- 

 fourth of the quantity, nor did the aqueous and 

 vitreous humours of a fheep's eye coagulate by the 

 like experiment : but the ferofity from an anafar- 

 cous leg, and that from the abdomen of a dropfical 

 perfon, and the cryflalline humour of a fheep's eye, 

 coagulated in the fame heat. 



3. When any of thefe capillary glands are Simu- 

 lated into greater irritative actions, than Is natural, 

 they fecrete a more copious material ; and as the 

 mouths of the abforberit fyftem, which open in 

 their vicinity, are at the fame time ftimulated into 

 greater aclion, the thinner and, more faline part of 

 the fecreted fluid is taken up again ; and the re- 

 mainder is not only more copious but alfo more 

 vifcid than natural. This is more or lefs trouble- 

 fome or noxious according to the importance of 

 the functions of the part affected : on the Ikin and 

 bronchia, where this fecretion ought naturally to 

 evaporate, it becomes fo vifcid as to adhere to the 

 membrane ; on the tongue it forms a pellicle* 

 which can with difficulty be feraped off; produces 

 the fcurf on the heads of many people j and the 

 mucus, which is fpit up by others in coughing. 

 OR the noftrils and fauces, when the fecretion of 

 thefe capillary glands is increafed, it is termed 

 fimple catarrh ; when in the inteftines, a mucous 

 diarrhoea - 9 and in the urethra, or vagina, it has the 

 name of gonorrhoea, or fluor albus. 



4. When thefe capillary glands become inflamed, 

 a (till more vifcid or even cretaceous humour is 

 produced upon the furfaces of the membranes, 

 which b the caufe or the effect of rheumatifm, 

 gout, leprofy, and of hard tumours of the legs, 

 which generally termed fcorbutic j all which will 

 e treated of hereafter.
