On account of a busy practice, college duties, etc., I have not been able to do so much as I could wish along this line. But my books so far have received so warm a welcome at home and abroad that I hope that this one more may be considered favorably, and not a perpetration. I have had valuable help in the preparation of the condensed repertory at the end of the work, who modestly prefer not to have their names mentioned.
