PREFACE TO SECOND EDITION
Reading edition
I take this opportunity of cordially thanking all who have assisted me, and specially I have to thank Mr. Joseph McCabe and Dr. H. D. R. Kingston for reading the MS. and the proofs in all their stages, and for pointing out verbal inaccuracies and suggesting improvements both in the matter and in the manner of presenting it. I am also much indebted to a lady, who does not wish her name to appear, for lightening the task of proof correction.
P. V.
