A cross sectional study of 2,638 Zambian school children 1,220 boys and 1,418 girls has been done in Lusaka to study the puberty process. Public and axillary hair, breast development and menarche were studied. Pubic hair appeared for the first time in the group of 9 year-old girls and 10 year-old boys. Axillary hair appeared at about the same time. Stage two of the breast bud appeared for the first time in the group of 9 year-old girls. The earliest case of occurrence of menarche was in a girl of 9.4 years. The mean age at menarche in Zambian school girls was 13.7.

The arterial blood supply, position, and length of the appendix were studied 103 Zambian cadavers. In 39.8%, more than one appendicular artery was found. In position, 43.6% were pelvic, and 20.3% retro-cecal. The average length of the appendix was 12.0 cm in males, and 11.4 cm in females. The prevalence of the dual blood supply and pelvic position, may partly explain the recorded rarity of appendicitis among Africans.

A cross sectional study of 2,637 Zambian school children (1,220 boys and 1,417 girls) between the ages of six and eighteen years was carried out to observe growth patterns. Five anthropometric measurements were taken. It was noted that the growth spurt commenced at the age of nine years in girls. The accelerated growth continued until the age of fifteen years after which the rate of growth was very small. In boys, the growth spurt commenced a year later and continued until the age of seventeen years. Height was compared with that of the European and Ghanian children from London and Accra respectively. Although the growth patterns were similar, the Europeans were taller and the Ghanians were shorter than Zambians in this age group.

Four variables were measured in the sigmoid colon of 103 Zambians (73 men). The mean results were as follows:- Length 32.9cm (men), 29.5cm (women); height of mesentery 8.2cm in both sexes; length of attachment of the mesentery was 10.3cm (men), 10.8cm (women) and thickness 3.0mm in both sexes. The findings are inconclusive throwing no light on the aetiolocy of sigmoid volvulus.

The morphology of the gall bladder, the length and mode of termination of the cystic duct, and the origin and distribution of the cystic artery were studied in 88 adult Zambians (61 men, 27 women). The origin of the cystic artery was the right hepatic artery (53%), and the common hepatic artery (41%). Hartmann's pouch was observed in 44% of gall bladders. The cystic duct usually opened into the common hepatic duct (91%); its average length was 2 cm.
