cafes. When this fails, a grain of aloes every hour will find its 

 way, if the bowel is not deftroyed ; and fometimes, I believe, if 

 it be, when the mortification is not extenfive. If the vomiting 

 continues after the pain ceafes, and efpecially if the bowelg be- 

 come tumid with air, which founds on being ftruck with the 

 finger, thefe patients feldom recover. Opiates given along 

 with the cathartics I believe to be frequently injurious in inflam- 

 mation of the bowels, though they may thus be given with ad- 

 vantage in the faturnine colic ; the pain and conftipation T in 

 which difeafe are owing to torpor or inactivity, and not to too 

 great aclion. See Clafs I. 2. 4. 8. 



III. Violent errhines and fialagogues. 1. Turpeth mineral 

 in the quantity of one grain mixed with ten grains of fugar an- 

 fwers every purpofc to be expected from errhines. Their oper- 

 ation is by inverting the motions of the lymphatics of the mem- 

 brane, which lines the noftrils, and the caverns of the forehead 

 and cheeks \ and may thence poflibly be of fervice in the hydro- 

 cephalus internus. 



Some other violent errhines, as the powder of white hellebore, 

 or Cayenne pepper, diluted with fome lefs acrid powder, are faid 

 to cure fome cold -or nervous head-achs ;' which may be effect- 

 ed by inflaming the noftrils, and thus introducing the fenforial 

 power of fenfation, as well as increafmg that of irritation ; and 

 thus to produce violent action of the membranes of the noftrils, 

 and of the frontal and maxillary finufes, which may by aflbcia- 

 tion excite into action the torpid membranes, which occafion tl 

 headach. They may be ufed on the fame account in amauro- 

 fis and in deafnefs. 



2. A copious falivation without any increafe of heat often at- 

 tends hyiteric difeafes^ and fevers with debility, owing to an in- 

 verfion of the lymphatics of the mouth, fee Clafs I. 1. 2. 6. The 

 fame occurs in the naufea, which precedes vomiting ; and is alfo 

 excitable by difagreeable taftes, as by (quills, or by naufeous 

 fmells, or by naufeous ideas. Thefe are very fimilar to the oc- 

 cafional difcharge of a thin fluid from the noftrils of fome peo- 

 ple, which recurs at certain periods, and differs from defective 

 abforption. 



IV. Violent diuretics. 1. If nitre be given from a dram to 

 half an ounce in a morning at repeated draughts, the patient 

 becomes fickifh, and much pale water is thrown into the blad- 

 der by the inverted action of the urinary lymphatics. Hence the 

 abforption in ulcers is increafed and the cure forwarded, as ob- 

 served by Dr. Rowley. 



2. Cantharides taken inwardly fo ftimulate the neck of the 

 bladder as to increafe the difcharge of mucus, which appears in
