The author states in his preface that it is his purpose to furnish an introduction to the field of virus diseases by reviewing the most recent literature and by summarizing the present status of virus investigation. He points out, quite rightly, that recent surveys of the whole field, or of its parts, have been full of gaps. It is unfortunate, therefore, that his book, while offering a valuable survey of certain aspects of the subject, is itself full of gaps and in general disappointing. The translator is evidently unfamiliar with virus terminology, and what appears to have been an attempt at literal translation has led to some all but unintelligible passages. There are also innumerable errors in spelling and punctuation, evidence of a regrettable lack of care in proofreading.
Workers in this field will find valuable the first section, of ninety pages, which presents a general consideration of virus diseases.
