Query: A Remarkable Medicine

The original book dates back some 20 years, and it was concise, to the point and informative. This new edition has been bundled with Mr. Dreyfus' biography, which may be interesting to some readers but it is not relevant to those seeking his views on the medication being discussed (phenytoin). The pertinent chapter is buried within the larger work and has to be sought out.I would recommend searching for his original book, unless you are particularly interested in Mr. Dreyfus' bio.
