Side 155 - And God said, Behold I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed ; to you it shall be for meat.
Side 255 - One particular only (though it may appear trifling) I will relate. Having often forgot which was the cat, and which the dog, he was ashamed to ask ; but catching the cat (which he knew by feeling) he was observed to look at her steadfastly, and then setting her down, said, so puss !
