sibility that tile death rates by birth order
are different for these two types of anomalies
of the nervous system. In Figure 100 the
rate for anencephalus (category 740) is
shown for Monterrey, although it is based
only on small numbers; this rate did not
increase for fifth and later births.
For El Salvador, the numbers of deaths
from anenceplaIlus and other anomalies of
the nervous system by birth order are given
in Table 109 (even though the base for rates,

Seventeen of the 58 deaths were of firstborn
infants and 16 others were of fifth or
higher birth orders. Both El Salvador and
Monterrey have high birth rates and thus
many births are of high birth order. While
the cause of these anomalies is not known,
the data are sufficient to show that inany
of these deceased infants were of high birth
orders. In Monterrey, 15 of the deaths (16.5
per cent) were of infants of the ninth or
