whereas, the use of cycloplegics is perhaps minimized. The practice of the author in pre scribing bifiocals in nonpresbyopic myopes previously uncorrected, while occasionally warranted, will not find universal approval as a routine procedure. His statement that photophobia may be the result of excessive use of the accommodative mechanism is to be doubted. There are a few typographical errors and the practice of describing the cylinder axis as seen by the patient instead of the examiner in his graphic illustrations is confusing. These critical comments do not invalidate the book as a useful text. It is a worthwhile addition to any ophthalmological library but it should not be the sole text of the student of refraction.
