The Irish Blue Book for 1872—the twenty-second Report of the Inspectors and Commissioners of Control of Asylums for the Insane in Ireland—did not appear in time to be reviewed in our issue for last October along with the Reports (for the same period) of the English and Scotch Commissioners. We now, however, take the first opportunity of noticing its contents, and only regret that our space is too limited to enable us to do them justice. The report is a most interesting one, and the appendices, which are very full and complete, bear evidence of the bestowal of much labour on their compilation.
