This book has much to recommend it. It is a summary of almost all laboratory procedures a clinical chemistry laboratory might be called upon to do, even in the most research-orianted univensity hospitals. The style of the text is particularly appealing, for it is direct, simple, and free of pedagogy. The methods described for the frequently used tests are well selected in general (one important exception in the reviewer's opinion is the omission of the simple techniques devised by Seligson for measuring urea nitrogen, ammonia, etc.).
