DISEASES CLASS I. 2. 



vefTels of the noftrils drink up their fluids, namely the thin and 

 faline part of the mucus, after it has been cooled by the atmof- 

 phere. Hence the abforbents ceafing to act, and the fecerning 

 yeiTeJs continuing fome time longer to pour out the mucus, a 

 copious thin discharge is produced, which trickles down the 

 noitrils in cold weather. This difcharge is fo acrid as to inflame 

 the upper lip ; which is owing to the neutral felts, with which 

 it abounds, not being reabforbed ; fo the tears in the fiftula lach- 

 rymalis inflame the cheek. See Clafs I. i. 2. 7. 



4. ExpeEloratio frigida. Cold expectoration. Where the 

 pulmonary abforption is deficient, an habitual cough is produced, 

 and a frequent expectoration of thin faline mucus ; as is often 

 feen in old enfeebled people. Though the ftimulus of the faline 

 fluid, which 'attends all fecretions, is not fufficient to excite the 

 languid abforbent veflels to imbibe it ; yet this faline part, to- 

 gether with the increafed quantity of the whole of the fetreted 

 mucus, flimulates the branches of the bronchia, fo as to induce 

 an almoft inceflant cough to difcharge it from the lungs. A 

 lingle grain of opium, or any other ilimulant drug, as a wine 

 poffet with fpirit of hartftiorn, will cure this cold cough, and the 

 cold catarrh of the preceding article, like a charm, by ftimula- 

 ting the torpid mouths of the abforbents into action. Which 

 has given rife to an indifcriminate and frequently pernicious ufe 

 of the warm regimen in coughs and catarrhs of the warm or 

 inflammatory kind, to the great injury of many. 



M. M. Half a grain of opium night and morning promotes 

 the abforption of the more fluid and faline parts, and in confe-* 

 quence thickens the mucus, and abates its acrimony. Warm 

 diluent drink, wine- whey, with volatile alkali. 



5. Unnanberior pallida. On being expofed naked to cold 

 air, or fprinkled with cold water, a quantity of pale urine is foon 

 diicharged ; for the abforbents of the bladder become torpid by 

 their fympathy with thofe of the {kin *, which are rendered qui- 

 cfcent by the diminution of external heat ; but the kidneys con- 

 tinue to fecrete the urine, and as no part of it is abforbed, it be- 

 comes copious and pale. This happens from a finiilar caufe in 

 .cold fits of agues ; and in lefs degree to many debilitated confti- 

 tutions, whole extremities are generally cold and pale. The 

 great quantity of limpid water in hyfleric cafes, and in diabetes, 

 belongs to Clafs I. 3. i. 10. I. 3. 2. 6. 



M. M. Tincture of cantharides, opium, alum, forbentia. 

 Tlatmel (hirt in cold weather. Animal food. Beer. Wine.
