444 The Principles of State Interference'is another of the Series of Handbooks on Scientific Social Subjects. It would be fitting to close our remarks on this little work with a word of commendation of the publishers of so many useful volumes by eminent writers on questions of pressing interest to a large number of the community. We have now received and read a good number of the handbooks which have been published in this series, and can speak in the highest terms of them. They are written by men of considerable knowledge of the subjects they have undertaken to discuss; they are concise; they give a fair estimate of the progress which recent discussion has added towards the solution of the pressing social questions of to-day, are well up to date, and are published at a price within the resources of the public to which they are likely to be of the most use."-Westminster Review, July, 1891.
