gnathion incremental maximum were synchronized or followed after the onset of the body height peak. 4. In conclusion, it may be possible to apply the annual increment rate of the body height as a tool for predicting the craniofacial growth study if sellagnathion growth is recognized as one of the representative dimensions of the structures, especially in girls.

Differences in use persist despite dental prepayment. In a prepaid dental plan in which members have no direct cost, high socioeconomic status, and high readiness, people still give regular periodic dental care low priority, according to Dr. Mata K. Nikias, School of Public Health and Administrative Medicine, Columbia University. She concluded that persons who join prepayment plans voluntarily a,re more likely to use dental care than persons who obtain coverage as a fringe benefit of their work group membership. The data from the study of the present plan do not support the view that voluntary dental prepayment appeals to those “persons requiring more than average amount of dental care.” Only one fourth of the persons eligible for dental care under Medicaid in Erie County, New York, actually received any care during a 2-year period, declared Drs. Robert M. O’Shea and G. Donald Bissell, Erie County Department of Health and the School of Dentistry, State University of New York at Buffalo. In 1965, the year immediately preceding Medicaid, Erie County spent $130,000.00 to pay approximately 5,800 vouchers. The county spent more than $4 million for dental services for more than 54,000 Medicaid recipients from early 1966 until April, 1968. The bills of approximately 6,000 persons per month were being paid by the time the program was 2 years old. There is a clear relationship between age and cost. More than 50 per cent of the youngest patients (5 years and under) had dental bills of less than $20.00, and the bills of almost all the young children were less than $50.00. The majority in all age groups under age 25 had total bills under $50.00. Only 36 per cent of those 56 to 65 and 39 per cent of those 66 and over had bills less than $50.00.

Polymorphism
Serial hand-wrist x-ray films of eighty-one pairs of twins were examined to investigate the genetics of ossification sequence polymorphism. Discordance in ossification sequence was 3.5 times more common between like-sex dizygotic twins than between monozygotic twins, with the difference being significant at the 0.01 level of confidence. These findings support the contention that the major part of variation in ossification sequence is genetically determined.
