82 DISEASES CLASS 1. 2. 3. 4. 



vessels of the nostrils drink up their fluids, namely, the thin and 

 saline part of the mucus, after it has been cooled by the atmo- 

 sphere. Hence the absorbents ceasing to act, and the secerning 

 vessels continuing some time longer to pour out the mucus, a 

 copious thin discharge is produced, which trickles down the 

 nostrils in cold weather. This discharge is so acrid as to in- 

 flame the upper lip; which is owing to the neutral salts, with 

 which it abounds, not being reabsorbed; so the tears in the fistula 

 lachrymalis inflame the cheek. See Class I. 1. 2. 7. 



4. " Expectoratio frigida. Cold expectoration. Where the 

 pulmonary absorption is deficient, an habitual cough is produced, 

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

 seen in old enfeebled people. Though the stimulus of the saline 

 fluid, which attends all secretions, is not sufficient to excite the 

 languid absorbent vessels to imbibe it; yet this saline part, to- 

 gether with the increased quantity of the whole of the secreted 

 mucus, stimulates the branches of the bronchia, so as to induce 

 an almost incessant cough, to discharge it from the lungs. A 

 single grain of opium, or any other stimulant drug, as a wine 

 posset with spirit of hartshorn, will cure this cold cough, and the 

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

 ting the torpid mouths of the absorbents into action. Which 

 has given rise to an indiscriminate, and frequently pernicious, use 

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

 flammatory kind, to the great injury of many. 



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

 the absorption of the more fluid and saline parts, and in conse- 

 quence thickens the mucus, and abates its acrimony. Warm 

 diluent drink, wine- whey, with volatile alkali. 



5. Urina uberior pallida. On being exposed naked to cold 

 air, or sprinkled with cold water, a quantity of pale urine is soon 

 discharged; for the absorbents of the bladder become torpid by 

 their sympathy with those of the skin; which are rendered qui- 

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

 tinue to secrete the urine, and as no part of it is absorbed, it be- 

 comes copious and pale. This happens from a similar cause in 

 cold fits of agues; and in less degree to many debilitated consti- 

 tutions, whose extremities are generally cold and pale. The 

 great quantity of limpid water in hysteric cases, and in diabetes, 

 belongs to Class I. 3. 1. 10. I. 3. 2. 6. 



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

 Flannel shirt in cold weather. Animal food. Beer. Wine. 

 Friction. Exercise. Fire.
