sexes combined give an average which is in the upper half of 

 the mesocephahc group. The small number of female skulls 

 makes the combined average rather unsatisfactory. Had the 

 sexes been in more equal proportions the average would have 

 been lower, and would have more correctly expressed the 

 general fact. 



The range of variation is 465c. c. if we include both sexes, 

 365c. c. if we take the male skulls alone. 



Of the male skulls, fifteen, or 51-7 per cent., are mega- 

 cephalic ; eleven, or 37'9 per cent., are mesocephahc ; while 

 only three, or 10'3 per cent., are microcephalic. One of the 

 females and one of the skulls of undetermined sex are at the 

 lower limit of the mesocephahc group ; the others are micro- 

 cephalic. 



Professor Flower has taken this measurement in seven 

 Moriori skulls, and these have an average capacity of l,396c.c. 

 The average of Sir William Turner's series of eight is still lower, 

 l,387c.c ; but in both groups the percentage of female and 

 doubtful skulls is higher than in mine. It is also to be noted, 

 as explaining my higher results, that the collections measured 

 by these two observers contain none of the skulls of excep- 

 tionally large size described by MM. de Quatrefages and 

 Hamy." The mean cranial capacity of the three males in 

 the Paris Museum is given by them as l,600c.c., of the two 

 females as l,565c.c., while one of the male skulls has a 

 capacity of l,785c.c. Sir William Turner's largest has a capa- 

 city of only l,492c.c.. Professor Flower's of l,560c.c., whereas 

 I show in my table three skulls whose capacity ranges from 

 l,580c.c. to l,650c.c. The three " Novara" skulls have a mean 

 capacity of l,428c.c. ; Dr. Barnard Davis's two adults of 

 l,475cc. 



Combining these measurements with mine — in all, sixty- 

 three skulls — we get the following results : Average capacity 

 of forty-seven male skulls, l,460c.c. ; average capacity of six- 

 teen skulls of female or of doubtful sex, l,326c.c. The male 

 Moriori skull is therefore low down in the megacephalic group. 

 The female is microcephalic.
