Salts when the Shootings are advanced to 
their utmofl Perfection, if at that Time the 
Nail be taken away carefully with a Pair of 
Nippers $ then foaking up the Liquor where 
the Nail lay with a little Brufh or Rag, dip 
the Glafs gently into Water, and hold it there 
a few Seconds. Hereby the Shootings are 
flopped, the Branches are left upon the 
Glafs in very good Order, and if another 
Glafs be put over them, guarded with Slips 
of Cork as directed page 36, they may be 
kept many Years. Sometimes indeed they 
will turn green (that is, grow nifty) but as 
their Forms continue, it takes but little from 
their Beauty.

Eye, being frequently above an Inch in

by Glaffes through the different Stages of 
their Progrefs; for the Microfcope difcovers 
on fome of them the Appearance of Flow- 
ers and Fruits, and fhews many curious Par¬ 
ticulars not elfe to be conceived. The 4th
