What reading level is Report On Economic Biology volume 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
Very briefly I wish to set forth the accounts given by different observers.
VerrilP states that " the eggs contain more or less perfectly developed larvae when laid ; and when they are mature or have been a few days attached to the hair, they burst open and allow the young to escape almost instantaneously, when moistened. Thus when the horse licks itself, or its companions, the moisture hatches the eggs, and the young larvae are transferred to the mouth by the tongue or lips.
Froggatt 2 states ..." These eggs are generally deposited on the jaw, shoulders, or flanks of the animal, from whence, through the animal licking itself, they are conveyed to the lips and mouth, the warmth dissolving the gluey secretion and hatching the enclosed maggot, thus enabling it to crawl out into the throat. " Neither of these statements are borne out by the observations here recorded.
Bracy Clark's account, 3 although given upwards of a hundred years earlier, is much more correct. He writes : " The eggs thus deposited I at first supposed were loosened from the hairs by the moisture of the tongue, aided by its roughness, and were conveyed to i The External and Internal Parasites of Man and Domestic Animals.
