IMPROVEMENT OF PPIYSIC. 225 



The root of the avcns^ iinlcfs gathered in 

 the beginning of the fpring, before the 

 fap by nourifhing, and pufhing out the 

 leaves has wafted its aromatic vertue, will 

 by no means anfwer what may be juftly ex- 

 pelled from it. Rhubarb ought not to be 

 brought into an apothecary's fhop under 

 ten years from the time of its gathering. 

 The flowers of the St. John's wort ought 

 to be gathered before they are full blown, 

 that their balfamic vertue may be pre- 

 ferved. The root of the angelica is good 

 for nothing unlefs it be gathered in the 

 winter. Sloes ought to be gathered be- 

 fore they are ripe, and the juice pre fled 

 out of them in this fl:ate, i. e. before the 

 harflinefs is foftened by the frofl:, if it be 

 deflorned for an afl:rino;ent. Marum ouo-ht 

 to be kept in veflels well clofed, left the 

 volatile part, in which its vertue refldes, 

 flaould evaporate. 



Still an ample field remains. 



But not for me, to others i give way. 

 Who choofe a lono:er courfe.
