But in 1681 Gerard Blasius had brought out at Amsterdam an Anatome Animalium, containing the results of all the dissections of animals that he could find; and the second part of this book, treating of Volatilia, makes a respectable show of more than one hundred and twenty closely-printed quarto pages, though nearly two-thirds is devoted to a treatise De Ovo et Pullo, containing among other things a reprint of Harvey's researches, and the scientific rank of the whole book may be inferred from bats being still classed with birds.

Troublesome insects, vampire bats, and the failure to introduce new blood into the degenerated herds, are responsible for its decline.

Bats also are very numerous, especially in the eastern forest region, where the vampire bat is a serious obstacle to permanent settlement.
It may be added that even bats are unable to cross large tracts of sea; and the fact that fruitbats of the genus Pteropus are found in Madagascar and the Seychelles, as well as in India, while they are absent from Africa, is held to be an important link in the chain of evidence demonstrating a former land-connexion between Madagascar and India.
Though generally nearly smooth, or but slightly scaly, the surface of some hairs is imbricated; that is to say, shows projecting scale-like processes, as in some bats, while in the twotoed sloth (Choloepus) they are longitudinally grooved or fluted.
