[Dart 1962, p. 126] From this comparison, it seemed justified to attribute to the Maka- pansgat specimen the same endocranial capacity as that of Sts 5, namely 480 This value accordingly has been included in my tabulations (Tobias !963. !967a. i968b)* One other Makapansgat specimen, the original parieto-occipital piece (MLD 1), led Dart to estimate for it a capacity of no less than 650 , by analogy with the claims made for the Kromdraai vault. However, it is probable that far too small a proportion of the vault of MLD 1 is preserved for the estimate to be reliable (Figure 10). Furthermore, Robinson showed • A "quite provisional" recalculation by Holloway (1970b and personal communication) based on 4 cranial measurements and on the thickness of the first-discovered Australopithecus specimen from Makapansgat, MLD 1, yielded a lower value, namely 435 However, further work clearly needs to be done on the capacity of MLD 37/38. ^ 18.
