THE ONLY WINGED ANIMAL THAT IS VIVIPAROUS, AND NURTURES ITS YOUNG WITH ITS MILK
Latine · Mayhoff 1906
Volucrum animal parit vespertilio tantum, cui et membranaceae pinnae uni. eadem sola volucrum lacte nutrit ubera admovens. parit geminos; volitat amplexa infantes secumque portat. eidem coxendix una traditur esse. in cibatu culices gratissimi.
English · Bostock & Riley 1855–57
Among the winged animals, the only one that is viviparous is the bat; it is the only one, too, that has wings formed of a membrane. This is, also, the only winged creature that feeds its young with milk from the breast. The mother clasps her two young ones as she flies, and so carries them along with her. This animal, too, is said to have but one joint in the haunch, and to be particularly fond of gnats.
