1 The ancients were not aware that the gall was produced from the eggs of the cynips, deposited upon the leaf or bark of the tree. Tan and gallic acid are its principal component parts.
2 A substance quite unknown now; but it is very doubtful if Pliny is rightly informed here.
3 A fungous gall, produced by the Cynips fungosa. It is not used for any domestic purpose at the present day.
4 This kind of gall is now unknown. Fée questions the assertion about its juice.
5 The Cynips quercus baccarum of Linnæus, one of the common galls.
6 The root cynips, the Cynips radicum of Fourcroi, produces these galls, which lie near the root, and have the appearance of ligneous nodo- sities. It is harder than wood, and contains cells, in which the larva of the insect lies coiled up.
7 This is a proof, as Fée remarks, that the ancients had observed the existence of the cynips; though, at the same time, it is equally evident that they did not know the important part it acts in the formation of the gall.
