This concise textbook on microchemical technic as applied to blood is essentially a book of methods. It is written presumably for the laboratory technician. Before the discussion of each method is a brief outline of the underlying principle. The methods are described in a clear and explicit manner, and examples of calculations of the results are given under each description. It is doubtful whether this book will be received in the English speaking countries, where the Folin system of blood analysis is employed. The author has seen fit to replace practically every method that is standard in this country with one of his own choice without any apparent justification. The book is well organized and clearly presented but it is doubtful whether it will be well received here.
