This is a hard, woody excrescence, offrom four to twelve lines in diameter, usu-ally globular and covered with tuberosities,and pierced, or not pierced, with a hole ;those in the first case, are light and whitish ;and those in the second, compact, heavy,and of a brown or green hue. These areseparated in commerce : the latter kind arecalled Blue Galls, and the former WhiteGalls. The blue are more esteemed thanthe white, being far more astringent.

This production is occasioned by thepuncture made by the female of the CynipsGalla! tinctoriœ, a hymenopterous insect(Fig. Oliv. Voy. dans l'emp. Ott. pi. 15), orby that of the Cynips Quercus Folii [Fig.Réaum, t. 3. p. 30. f. 13), in the pedunclesof several species of oak, particularly theQ. Infectoria and the Q. Cerris, trees of AsiaMinor, in which to deposit its eggs, roundwhich this tumour forms, acting as a de-fence, subsequently, to the larvae.
