1159. O. rotundifolia Link. enum. ii. 452. Dietr. sp.pl. i.249. 

 — Fraxinus rotundifolia Linn. sp. 1510. — Calabria and the 

 Levant. 



Very like the last. Leaflets subsessile, roundish, ovate, acute, 

 coarsely serrated, quite smooth underneath, entire and rather cuneate 

 at the base. — This also yields Manna, and according to Tenore of 

 better quality than the last. 



Fee says that this substance is also obtained from Fraxinus excel- 

 sior, and parvifolia, which agrees with Dr. Fothergill's statement ( Works, 

 p. 143.). " In Calabria and Sicily, in the hottest part of the summer 

 months, the Manna oozes out of the leaves, and from the bark of the 

 trunk and larger branches of the Fraxinus or Calabrian ash. The Ornus 

 likewise affords it, but from the trunks and larger branches only and that 

 chiefly from artificial apertures ; whereas it flows from the Fraxinus 

 through every little cranny and bursts through the large pores spon- 

 taneously. The different qualities of the Manna are from different parts 

 of the tree." 



1160. Fraxinus excelsior Linn, (the Common Ash) not only 

 yields Manna, in the warm climate of the South of Europe, as 

 has just been stated, but is reported to have a tonic febrifugal 

 bark, and leaves almost as cathartic as those of Senna, producing 

 an unequivocal action upon the kidneys. 



1161. Syringa vulgaris Linn, has some reputation as a cure 

 for intermittent fevers. The unripe fruit is singularly bitter 

 without any acrimony, and according to Curveiller an extractof 

 it is a remarkably good tonic and febrifuge.
