284 A Treatise on 
coarfe Sugar mixed with Honey and a little Scam- 
mony •, whence it fometimes purges more violently 
than the others. Moreover, under the Name of 
Manna we frequently meet with denfe, white and 
opake Maffes, which are made of Sugar and Manna 
boiled together to the Confiftence of a folid Elec- 
tuary : But this factitious Sort is eafily diftinguifhed 
from the genuine, by its Weight, Opacity, and 
different Taffe. 
Manna is got from two Sorts of Alb-Trees. Th£ 
one is called Fraxinus humilior , five altera Fheophrafti , 
minor e et lenuiore folio , C. B. P. 416. Ornus , Ludg . 
83. The other is called Fraxinus rotundiore folio , 
C. B. P. 416. Ornus , Quorumd. They differ fome- 
thing from our common Afh, named Fraxinus ex- 
cel for ^ C. B. but not fo much as to be properly 
accounted diftindt Species. The Manna flows from 
them in Calabria , and Sicily, either fpontaneoufly 
or from Incifions. 
In Calabria , from about the twentieth Day of 
June to the End of July, provided the W eather be 
fair, it iffues fpontaneoufly from the Trunk and 
large Branches of thefe Trees, continuing to flow 
from Noon till Evening under the Form of a clear 
Liquor, v/hich gradually thickens into hard white 
Grumes. If the following Night be ferene, they 
ferape the Manna off in the Morning with wooden 
Knives ; but if the Weather during the Night have 
been wet or foggy, it melts and is entirely loft. 
When they have gathered it, they put it into un- 
glazed earthen Veffels. Afterwards they expofe it 
to the Sun in white Papers fpread upon Boards, till 
it becomes fo dry as not to adhere to the Fingers. 
This is called Manna fpontanea , fpontaneous Manna , 
and Manna di corpo , Manna of the T runk. 
About the End of July , when the Juice ceafes to 
flow, the Country- People make Incifions into the 
Trees,
