more than that of male Eurojiean sknlls, the average cajjacity of 317 of 

 which Topiimnl found to 1x3 lofJO That nt tho rt)«n(I-hoa4led females 

 Ls 1,311 ec, or 61 cc. less than Emxipeftn fpraalo skulls, 232 of which, 

 measured by Topiuard, averaged 1,375 cc. White the capacity, therefore, 

 of tlie male skulls from Timnr-taat is, on an average, larger than those 

 of EiJroi»ean, that of the females is less thau in Europeans of the samesex. 

 Tho difference in capacity Ixitweeu nialoa and females of Timor-lautis 2116 

 cc. ; that between Euroi)caiis is 185 cc. The individual range of 

 capacity ia considerable, one of the maJe skulls (No. 10) being no Icsa 

 than 220 cc. Rinaller than any of the others. The largeRt capacity, that 

 of No. 4, is 1,780 cc, and the smallest 1,395 cc. that of No. 10. In the 

 females the range is from 1,105 to 1,240 cc. The difiference, then, lietween 

 the lai^st and araalleat male skulls is 385 cc, and 155 cc, between those 

 of femiles. The long-heatled female has a capacity of 1,100 cc. 



Cenkdir Imfejc. — In the round skulls the relative proportion of the 

 breadth to tho length varies little in the two s^xes; the cephalic index 

 of the males avcraginf^ 8^< l and of the females 8t> 0. Riference to the 

 table will show that the lower index of the females is chiefly caused by 

 the almost undeformed cranium. No, 2, which lias an index of only 78*9. 

 All these skulls Iwlong to Broca's clas.s of true brachycephalic (skulls in 

 which the cephalic index is over 83*33) except No, % which is sub- 

 lirachycephaltc (Iwtween SO'Ol and 83'33), on account of its width being 

 less than, while the length is the same as that of the others. The long 

 narrow female skull has au index of 711,and lielongs, therefore, to Broca's 

 true dolichocephalic group. 



Htighf Imlrx. — This averages about 2- higher in the male brachycephalic 

 skivlls than in the corresponding females, being 80-6 in the former, 

 and 82*4 in the tatter. The cejihalic imiex of tho males wo found 

 was higher by tho same amovmt than that of the females. In the 

 dolicbm-ephalie female the right index is much lower than in the 

 l»rachTcephalic skulls of the same sex, a condition which the late 

 Professor Ralle.ston found esually to obtain. The height of the skulls is in 

 all instance.s Ieii« than the breadth, except in the female No. 2. The 

 indices of height and breadth above given cannot be taken as strictly 

 accurate, owing to the artilicml fljittening of the posterior or postert)- 

 lateral portion of most of tho crania, but are as nearly accurate as cir- 

 cumstances will admit, and general deductions may probably be relied 

 npfm. 



The height in proportion to the breiulth (the latter being taken as 100) 

 is in the males as 91 2, and in the females as 95'b to 100. 



Cifcum/trtni-e. — The horizontal circutnferenoe of the braehycophalio 

 skulls averages in tho males 507 mm., that of the females 175 mm., while 

 the transverse vertical circumference of the former is 150 mm., and of the 

 latter 421h' mm. Tho total longitudinal circumference averages in the 

 males 5012 mm., and in tho females 473 mm. In each of the tliree 

 circumference measurements, thertjfore, the female skulls are on an 

 average about 81 ram. smaller than the males. The dolichocephalic 

 ffrmale shows considerable differences in the various circumferences from 

 the previous skuHs of the same sex. Its horizontal and total longitudinal 

 circuraferences are each 25 mm. greater than the averi^e of these 

 measurements in the brachycephalic sknlls, while its transverse vertical 

 circumference is 17"6 mm. less. The increased size of the two first 

 circumferences in this skull is due to the greater antero-posterior length 

 of the frontal and especially the parietal iKjnes ; the other eegmeats being 

 almost the same in both varieties of skulls. This accords with the fact 

 pointerl out by M, Gratiolet, that in women the elongation of the cranium
