46 DISEASES CLASS I. 1. 4. 13. 



oiled leathers should be nicely put round the joints of the ma- 

 chine; and a wet cloth round the injecting pipe to prevent the 

 return of the smoke by the sides of it. Clysters of carbonated 

 hydrogen gas, or of other factitious airs, might be tried; or of 

 the hairs of siliqua hirsuta. 



Harrowgate water taken into the stomach, so as to induce six 

 or seven stools every morning, for four or six weeks, is perhaps 

 the most efficacious method in common use. A factitious Har- 

 rowgate water may be made probably of greater efficacy than 

 the natural, by dissolving one ounce of marine salt, (called bay 

 salt,) and half an ounce of magnesia Glauber's salt, (called Ep- 

 som salt, or bitter purging salt,) in twenty-eight ounces of water. 

 A quarter or half a pint of this is to be taken every hour, or two 

 hours in the morning, till it operates; with a tea-spoonful of a 

 solution of liver of sulphur, which is to be made by putting an 

 ounce of hepar sulphuris into half a pint of water. See Class 

 IV. 1. 2. 9. 



13. Dracunculus. A thin worm brought from the coast of 

 Guinea. It is found in the interstices of the muscles, and is 

 many yards long; it makes a small ulcer; which is cured by 

 extracting an inch of the worm a day, and wrapping the extract- 

 ed part slowly round a bit of tobacco-pipe till next day, so as not 

 to break it. I have twice seen long worms, like a thick horse- 

 hair, in the water in July in this country, which appeared hard 

 and jointed. 



14. Morpiones. Crab-lice. The excrement of this animal 

 stains the linen, and appears like diluted blood. 



M. M. Spirit of wine. Mercurial ointment, shaving the part. 

 Oil destroys other insects, if they be quite covered with it, as the 

 ticks on dogs, and would probably therefore destroy these. Its 

 manner of operation is by stopping up or filling their spiracula, 

 or breathing pores; a few drops of oil poured on a wasp, so as to 

 cover it, destroy it in a few seconds. 



15. Pediculi. Lice. There is said to" be a disease in which 

 these animals are propagated in indestructible numbers, so as 

 to destroy the patient. 



M. M. Cleanliness, mercurial ointment, stavis acria in pow- 

 der, or the tincture of it in spirit of wine. Spirit of wine alone? 

 Bath of oil?
