Without advancing any theory touching the progression of the mother's song to her babe, other than declaring lullabies to be about as old as babies, a statement which recalls to mind an old story, entitled "The Owl's Advice to an Inquisitive Cat."

"O cat," said the sage owl of the legend, "to pass life agreeably most of all you need a philosophy; you and I indeed enjoy many things in common, especially night air and mice, yet you sadly need a philosophy to search after, and think about matters most difficult to discover." After saying this the owl ruffled his feathers and pretended to think.

But the cat observed that it was foolish to search after such things. "Indeed," she purringly said, "I only trouble about easy matters."

"Ah! I will give you an example of my philosophy, and how inquiry ought to be made. You at least know, I presume," scoffingly exclaimed the owl, "that the chicken arises from the egg, and the egg comes from the hen. Now the object of true philosophy is to examine this statement in all its bearings, and consider which was first, the egg or the bird."

The cat was quite struck with the proposition.

"It is quite clear," went on the owl, "to all but the ignorant, one or other appeared first, since neither is immortal."

The cat inquired, "Do you find out this thing by philosophy?"

"Really! how absurd of you to ask," concluded the feathered one. "And I thank the gods for it, were it as you suggest, O cat, philosophy would give no delight to inquirers, for knowing all things would mean the end and destruction of philosophy."

With this owl's apology nursery-lore is presented to my readers without the legion of verified references of that character demanded as corroborative evidence in the schools of criticism to-day.

A few leading thoughts culled from such men as Tylor, Lubbock, Wilson, McLennan, Frazer, and Boyd Dawkins, etc., the experiences of our modern travellers among primitive races, Indian and European folk-lore, the world's credulities past and present, have helped me to fix the idea that amongst the true historians of mankind the children of our streets find a place.
