RESUMEN
In the city of Esmeraldas, north-western coast of Ecuador, height, weight, and body composition of 600 male and female schoolchildren of African ancestry in the age groups four, five and six years were investigated. All the children were apparently healthy without any obvious or reported pathologies and in accordance with data from personal information were assigned to one of two socio-economic classes. The greater values for weight and height shown by children in the higher socio-economic group than in the less well off are compatible with those for more fat and water as obtained by the BIA investigation. Additional information on nutritional, muscular and general health status was obtained from positioning and degree of dispersion of the 'Biagram' ellipses. It seems that both the anthropometric and the bioelectrical impedance methods provide useful information on the differences due to belonging to one or other of the socio-economic groups.

Variation in the nature and extent of division of the hypoglossal canal can be classified by a simple scoring scheme. Applied to three series of crania of differing provenance, the results indicate a continuity in expression of the trait rather than the dichotomous character utilized in previous studies. The similarity in results in these three populations, of widely differing environment, suggests fairly strict canalization of development.
