In some cases the Redi or Sporocysts do not give rise to tailed Cercari, but to tailless forms.
Redi found that birds could sustain the want of food from five to twenty-eight days.
In most Redi there is a special opening, not far from the mouth, by which they pass out.
Borelli in mathematics, Redi in natural history, and many others, enlarged the boundaries of knowledge.
Redi, as we have seen, traced the maggots of putrefying flesh to the eggs of flies.
