Essays in Historical Chemistry. By T. E. Thorpe. (Macmillan and

Co.)—These lectures, some of which were delivered as far back as 1870, make a most interesting volume. Professor Thorpe is a good lecturer ; but those who have not heard him, can do the next best thing by reading him. There are essays to suit technical tastes, and others to suit those who prefer more of the personal element. The essays on Thomas Graham are the best in the book, though many will read with pleasure the chapters on Cavendish and WOhler.
