THE WREN'S INK.

A phial of the colourless writing fluid to which this name has been given, and a few sheets of the prepared paper, have been sent to us for trial. The fluid is limpid, and flows freely from the pen; and when it touches the paper it turns to a pale blue—faint, but legible: the writing appears as if common blue ink very much diluted were used, or it had been blotted while wet. The chief recommendation of the Queen's Ink is, that it will not soil any article of dress or furniture on which it might be spilt, and over books and prints it flows harmlessly: though, if left to become dry, a slight stain, as of wet, is visible. The paper written on is of the ordinary colour and texture of Bath post; the ink soon dries, and admits of erasure.
