the doctor's laboratory, when your chemical experiments have been going on, is it not very natural to suppose that a drop of one of the acids might have fallen on my clothes? I have seen your waistcoats stained, I am sure. Really, Mr. Campbell, you are unfriendly, uncharitable; your partiality for Mr. Forester should not blind you, surely. I know you want to exculpate him from having any hand in the death of that cat: but that should not, my dear sir, make you forget what is due to justice. You should not, permit me to say, endeavour to criminate an innocent person." "This is all very fine," said Henry; "and you may prove your innocence to me at once, Mr. Mackenzie, if you think proper, by showing that the waistcoat was really, as you assert, stained by a drop of vitriolic acid falling upon the outside of it. Will you show us the inside of the pocket?" Mackenzie, who was now in too much confusion to know distinctly what Henry meant to prove, turned the pocket inside out, and repeated, "That stopper was never in my pocket, I'll swear." "Don't swear to that, for God's sake," said Henry. "Consider what you are saying. You see that there is a hole burnt in this pocket. Now if a drop of acid had fallen, as you said, upon the outside of the waistcoat, it must have been more burnt on the outside than on the inside." "I don't know--I can't pretend to be positive," said Archibald; "but what signifies all this rout about the stopper?" "It signifies a great deal to me," said Dr. Campbell, turning away from Mackenzie with contempt, and addressing himself to his ward, who met his approving eye with proud delight--"it signifies a great deal to me. Forgive me, Mr. Forester, for having doubted your word for a moment." Forester held his guardian's hand, without being able for some instants to reply. "You are coming home with us, Forester?" said Henry. "No," said Dr. Campbell, smiling; "you must not ask him to come home with us to-night. We have a little dance at our house to-night. Lady Catherine Mackenzie wished to take leave of her Edinburgh friends. She goes from us to-morrow. We must not expect to see Forester at a ball; but to-morrow morning--" "I see," said Forester, smiling, "you have no faith in my reformation. Well, I have affairs to settle with my master, the printer. I must go home, and take leave of him. He has been a good master to me; and I must go and finish my task of correcting. Adieu." He abruptly left Dr. Campbell and Henry, and went to the bookseller's, to inform him of all that had passed, and to thank him for his kindness. "You will be at a loss to-morrow for a corrector of the press," said he. "I am determined you shall not suffer for my vagaries. Send home the proof-sheets of the work in hand to me, at Dr. Campbell's, and I will return them to you punctually corrected. Employ me till you have provided yourself with another, I will not say a better hand. I do not imagine," continued Forester, "that I can pay
