Observations on animal and human infants suggest that malnutrition during a critical period of early life results in short stature and may, in addition, permanently and profoundly affect the future intellectual and emotional development of the individual. In human beings, it is not known whether these results may be caused by malnutrition alone or whether such intimately related factors as infection and an inadequate social and emotional environment contribute significantly t,o the problem. Field studies to test these hypotheses are, at best, difficult to design and to carry out; it seems likely that it will prove impossible to separate clearly t,he individual effects of malnutrition, infection, and social environment. While progress has been made in understanding the biochemical development of nervous tissue, little is known of the effects of nutrition on the physiologic processes of these organs ; nor is there adequatt> information on the relation between mentation and cellular metabolism.

Most of the fatal diseases are known to have a positive relation to genetic background. Almost, 1,500 hereditary human conditions, most of which interfere with function, are known and the number is increasing with the widening of medical science. With the exception of identical twins, every living being is genetically unique. Environment can modify the manifestation of the genetic program in the individual. The characteristics of every person are the products of the interaction of heredity and environment. Environment presents a challenge to heredity and modifies the effects of genes.

Hereditary disease is treatable to a limited extent. Congenital malformations are gross structural defects present at birth. The orthodontists, in changing or eliminating structural or morphologic anomalies, may be converting an undesirable genotypical condition into a desirable clinical phenotype. Gene action can be influenced by environmental factors. The orthodontist, therefore, is not working in vain. Differences in identical twins are due to environmental factors. This shows itself in the occurrence of cleft palate in only one of a pair of identical twins. Family history and consanguinity should be determined. This volume is replete with information which should prove of interest to the orthodontist. Orthodontics, Jot6

The authors of this text are well known and highly respected because of their contributions to the orthodontic literature, not only in Spanish-speaking countries but wherever orthodontics is practiced. The first 100 pages are devoted to a discussion of growth and development and the physiology of the dentomaxillo-facial complex. Diagnosis is presented from the etiologic and pathologic aspects. More than 60 per cent of this text is devoted to treatment. All of the American methods and some of the European methods of treatment are presented and illustrated. Prognosis, the authors point out, is important for the operator so that he may know the limitations of treatment in a particular case. It is also of importance in explaining to the patient and his parents how much improvement they can expect. The illustrations are clear and practically self-explanatory. This text should prove of practical value, even to those who are not conversant with the Spanish language. J. A.

It is the exception to find a case in which a short frenulum actually affects speech sound production. When there is a tongue-tie, the sounds that may be affected are tongue-tip sounds, such as T, D, N, L, SH, S, ZH, R, 2, and TH. Although many of these sounds may be produced with the tongue tip elevated, they may also be produced with the tongue depressed behind the lower incisors, still resulting in good sound production. Elevation of the tongue tip is not necessary in vowel sound production. The tongue-tip sounds mentioned above are the semivowels and consonants which may be affected. The TH sound, as in “the” or “think,” utilizes tongue-tip activity but does not have to be made with the tongue tip over the incisors; one can make an adequate TH sound, keeping the tongue tip positioned behind
