without a probable cause; but is said to have been considered by them as a resemblance of divinity, as being the only animal that is without a tongue. For the divine reason is unindigent of voice, and proceeding through a silent path, and accompanied with[40] justice, conducts mortal affairs according to it.

For not being able to lay their eggs in the water, and fearing to lay them far from it, they have such an accurate pre-sensation of futurity, that though they enjoy the benefit of the river in its access, during the time of their laying and hatching, yet they preserve their eggs dry and untouched by the water. They also lay sixty eggs, are the same number of days in hatching them, and those that are the longest lived among them, live just so many years; which number is the first of the measures employed by those who are conversant with the heavenly bodies. “Moreover, of those animals that were honoured for both reasons, we have before spoken of the dog.
