When the naturalift is in feareh of vegetable 

 productions, different foils and fituations mould 

 be examined-, as the fea, and its fhores, deep 

 running waters, dikes, marines, moors, moun- 

 tains, cultivated and barren fields, woods, rocks, 

 &V. afford each their peculiar plants ; and 

 wherever any are collected, the particular foil 

 and fituation fhould be remarked. 



From the moift meadow to the witherM hill, 

 Led by the breeze, the vivid verdure runs, 

 And fwells, and deepens, to the cherinYd eye (/>). 



Sometimes it may prove inconvenient to convey the 

 plants which may be difcovered, when it would not 

 be fo to fend them dried in the form of a hortus- 

 ficcus. To do this in the beft manner, and to 

 make their {talks, leaves, &c. lie fiat and fmooth, 

 they muff be expofed betwixt papers to a free 

 dry air, with considerable preffure upon them. 

 The leaves and flowers mould be carefully ex- 

 panded, for on this the beauty and value of the 

 fpecimen greatly depends. Thofe plants fhould 

 alfo be gathered on a dry day, while they are in 

 full bloom, and all their parts perfect and entire. 

 When perfectly dry, they may be kept either 

 loofe in quires of paper, or fattened into a book, 

 with glew made of fine ifinglafs diffolved in boil- 

 ing water. Particular care is to be taken to 

 avoid any injuries from moifture, or infects ; to 

 prevent any accident from the latter, let the 

 paper and {talks of the plants be lprinkled with 

 the fublimate folution, (Sect I. p. 10.)

 paper, look very little inferior to the belt draw-
