Among the remedies which have been tried in this 

 ^disease, the most celebrated is that devised by Boyle, 

 the name of it is Ens Veneris, It is composed 

 of sal armoniac and edulcorated colcothar, two or 

 three times sublimated together ; the dose is from 

 three to six grains taken in a suitable liquid at bed 

 time. I suppose that the efficiency of this drug 

 chiefly depends on the sal armoniac, as that is 

 specially suitable, on account of the extreme tenuity 

 of its parts, for removing the obstructions that pro- 

 duce this disease. And it is likely that the flowers 

 of sal armoniac will in this disorder be as eff'ectual, 

 or even more ; for while the sal armoniac is sub- 

 limed along with colcothar, a narcotic sulphur from 

 the colcothar, of an earthy or cupreous nature, sub- 

 limes with the sal armoniac. Now this sort of sulphur 

 does not seem very suitable for this disease. 



An artificial salt, of an ammoniacal nature, and of 

 great virtue, can be prepared as follows : — 



^ Sal. volatile C. C. Sanguinis^ aut Urines s. q. quibus 

 phialce oblongcB immissis, sp. sal. rectijicat, aut etiam suiph. 

 per Camp an. rectific. guttatim affundatur^ quousque ebullitio 

 non amplius excitabitur : sal hie resolutus^ per filtrum tra- 

 jiciatur^ &^ leni calore ad siccitatem salts abstrahatur. Dos. 

 gr, iij. ad vj. primo mane, aut hord somni in liquore appro- 

 priato.
