Not illustrated. 1730 Excerpt: ...any antecedent Dissolution. Dr. Willis adds this Gum in the Distillation of Spiritus Salts Ammoniad, which Spirit will produce Ghryftals of a triangular Form. Manna is the Gum proceeding from an Asti Tree, frequently growing in Italy, of Which Sort I have imported several which are now flourishing in England. The Manna: issues from this Tree by making Incisions in the Bark in April; but sometimes G % we we find it upon the Leaves, when they arc nearly ripe, at the latter End of September. It is said to be gathered, by most Writers, from the Leaves, only in dewy Mornings; but considering the great Quantities we have of it from abroad, we may be well assured it cannot be worth the While of the People in foreign Countries to gather it at the easy Rate which we receive it.

The Juice is boyl'd till it comes to the Consistence of Honey, and is then put up into Cases as we receive it. It is extreamly bitter to the Taste, and therefore is seldom used in any liquid Shape, but is chiefly made into Pills; so that the Dose may be given to Half a Dram.

It is of great Use in such Cases where the Vessels ...
