Abstract
THE work which the universities were invited to undertake in preparing synthetic drugs and “poison gases” in more than usual laboratory quantities forced them to replace their costly glass and porcelain apparatus, wherever possible, by larger and stronger vessels of tinned iron and by earthenware basins of cheap material. This experience has been wisely turned to account in the new edition of Mr. Barnett's book, in which a description of such apparatus is given. Although it is desirable for the beginner to use transparent vessels, in which reactions can be easily watched and controlled, and to manipulate quantities which do not demand too great an expenditure of time, the knowledge of how to apply larger scale methods he may later be called upon to adopt wall prove invaluable. Moreover, the habit of discarding, as occasion demands, the usual laboratory vessels in favour of less elegant but more serviceable utensils is a good mental and moral exercise. With the exception of the above-mentioned description and the addition of a few new preparations, no fundamental change has been made in the size and scope of the new edition. It takes the form made familiar by Gattermann's and Freundler's well-known treatises, and by many other books dealing with this subject.
