I HAVE attentively read Mr. John Penrose's Treatise on Practical Arithmetic, and look upon it to be one of the completest of the kind for youth I have ever seen, not only for a variety of examples, in all the useful parts of Arithmetic, but also for the judgment, strength and plain manner with which Mr. Penrose has handled the whole of this useful part of knowledge. Waterford, January 13, 1824. NICHOLAS WALSH: I HAVE examined Mr. John Penrose's Arithmetie: from the arrangement' of the work, and conciseness of the methods, I consider it entitled to public approbation. MICHAEL O'CONNELL. Waterford, February 5, 1824.
