died is the training of eye movements of people with aphakia (because, he points out, the lateral movements of their eyes are longer than those of readers who have not had the operation). Their visual training program has also cured children of chronic stomach cramps, nausea and headaches.
The concepts and methods described in this book contrast markedly with those emphasized by most other texts on reading problems. Moreover, the high incidence of functional ocular abnormalities that the author mentions—60% of all students—has nowhere been documented by other investigators.
This book makes it quite clear that the medical profession must take a responsible interest and part in evaluating the ocular status of retarded readers.

READING DISABILITY: DEVELOPMENTAL DYSLEXIA. By Lloyd J. Thompson, A.B., M.D. Springfield, Illinois, Charles C Thomas, 1966. Clothbound, 201 numbered pages, 4 figures. Price: $8.75. This book is a psychiatrist's summary of
the arguments favoring the hypothesis that most reading defects are innate, that they represent a resultant "developmental lag" that is genetically determined.
In a brief historical review of the subject we learn, interestingly, that it was an English ophthalmologist who, in 1896, first recorded detailed observations on a patient with a reading disorder. Probably the famous Edward Jackson of Denver was the first to cite such observations in this country when he read a paper on "Congenital word blindness" before the Colorado Medical Society in 1905. The use of such a designation by ophthalmologists at that time to describe reading disorder was compatible with their theory that reading defects were usually secondary to brain damage or caused by an organic lesion in the brain. They were almost unanimous in pointing out that the disorder
was not caused by any dysfunction or dis- i ease of the eyes.
Other medical specialties became interested in reading and, in 1925, Orton, a psychiatrist, wrote a paper which attributed reading disorders to an innate defect that was expressed as a developmental lag in Ian- ' guage skills. He noted that these children usually have other language disorders as well, including imperfect speech, a poor ear for words and a meager oral vocabulary. Their motor skills develop more slowly and they exhibit more awkward motor control (poor handwriting, etc.), longer retention of tonic-neck reflex-attitude responses and more variable motor tone than normal. They frequently come from families in which there is left-handedness, more than one language spoken, and reading, spelling and " motor co-ordination defects. Orton and his disciples felt that there was no need to postulate brain damage in these children but rather that these defects all reflected developmental abnormality. Thus the term "developmental dyslexia" originated.
The author of this book is an Orton disci- , pie. He admits, however, that there are, rarely, other possible sources of reading defects (organic damage in the central nervous system, emotional, environmental or psychologic disturbances). But he feels that these other factors often merely intensify , effects in "a specifically prepared physiological soil."
The author likens the inheritance of reading abilities to other sensory and motor abilities such as a feel for rhythm, an ear for music, memory, emotional expressiveness, . motor co-ordination, depth of feeling and even color vision. His analogy fails with color vision particularly, for there is no sensitivity continuum from exquisite discrimination of all shades of color to ability to recognize only shades of black and white ι that is comparable to the apparent gradations in the other "abilities."
The crux of the developmental-lag theory is the supposed genetic nature of the defect.

The author naively states that studies of the chromosome are being carried out on the assumption that some unusual genetic complication may be found, but he gives no references. (Are there any geneticists doing chromosome studies for a "reading defect"?)
Obviously there are educators, physicians and psychologists who do not accept a "developmental lag" as the predominant cause of reading disorders, and the author acknowledges this fact. But he does not adequately describe their objections. An important observation of many educators is that children with reading problems often do not show many of the other deficiencies that Orton associated with "developmental dyslexia" (many have only the reading problem). Even some of the author's own case reports are not convincing examples of developmental lag but rather suggest other causative factors.
This book quite rightly exmphasizes the importance of the reading problem. "Among school children in this country (6 to 17 years of age), over 10 per cent of those not mentally retarded are more than 2 years retarded in reading according to their mental age ability." However, a reading problem at a young age has not prevented significant achievement for some gifted individuals (for example, Woodrow Wilson, Thomas A. Edison, August Rodin, Paul Ehrlich and Gamil Nasser). An interesting suggestion of the author is that Lee Harvey Oswald had developmental dyslexia. He presents evidence for this contention and then "wonders what the outcome might have been if the handicap had been recognized when he started his schooling and appropriate remedial reading had been utilized at that time."
The author offers many suggestions for attacking the widespread problem of dyslexia at various levels. He urges that schools identify developmental dyslexia as early as possible and that reading instruction begin at the age of four or five years. Some edu
cators would not approve of this latter suggestion because not all children are "ready" to read by the age of four or five (irrespective of whether or not they have reading problems at a later age).
This book is valuable for its detailed description of the developmental-lag theory of reading disability.

T H E DISABLED READER: EDUCATION OF THE DYSLEXIC CHILD. Edited by John Money. Baltimore, The Johns Hopkins Press, 1966. Clothbound, 421 pages, 21 figures (including 3 that are in color), 17 tables. Price: $8.50. This book is a collection of independent
writings discussing principles of the reading process, teaching beginning readers and the diagnosis and treatment of reading problems. It was assembled by combining original chapters from 13 contributors with four chapters reprinted from already published material. The contributors include psychologists, educators, a linguist and a psychiatrist.
Most modern teaching programs for beginning readers attempt to solve that troublesome truth about the English language: the inconsistent relationship between its phonology and its orthography. (For instance, ough can appear as plough, ought, rough, though, cough, or through and, as G. B. Shaw pointed out, ghoti should be pronounced just like fish : gh as in rough ; o as in women; and ti as in nation.) One program uses an artificial alphabet with consistent sound-symbol relationships (The Initial Teaching Alphabet). Eventually the child transfers to the regular alphabet. Another method superimposes consistency on existing letters by assigning a given color to a letter or a compound of letters if the phonetic or sound value is the same. A third method uses a "linguistics" approach. Initially only letter combinations with regular or consistent relationships between sounds
