our own deductions derived from a study of this material upon those who may hold 

 different opinions from ourselves, and hence we do not incorporate here, nor did we 

 do so with the Tasmanian tracings, the result of our own observations on highly 

 debatable questions, with the material itself. The conclusions which we ourselves 

 drew from the Tasmanian material have been published in the Proceedings of the 

 Royal Society of Edinburgh, Volume 31, 1910, and similarly the conclusions which 

 it is our intention to deduce from the present material will be made available 

 elsewhere, and in due course. Thus those who desire to make use of the present 

 material for other purposes will have a free hand both now and for the future. That 

 this procedure is the correct one is, we think, justified by the many private 

 communications which have reached us from Anthropologists in all parts of the 

 world, and by the further fact that Professor Sergi, of Home, Dr. F. G. Parsons, of 

 London, Mr. L. W. G. Biichuer, of Melbourne, and others, have already availed 

 themselves of the opportunities afforded by the Tasmanian publication. 



Such being the objects and aims of the present work, we may now be 

 permitted to point out that we have herein reproduced dioptrographic tracings of 90 

 Australian aboriginal crania in three life size norma?, namely, norma lateralis, norma 

 facialis, and norma verticalis, lettered respectively and uniformly A, B, C. 

 Concerning the choice of both the total number of crania and of the normae recorded, 

 this has been solely restricted by the cost of reproduction. Had there been an 

 unlimited supply of money available, we could easily have dealt with all four normae 

 of several hundred Australian aboriginal crania. Lack of funds alone has prevented 

 our doing so. 



The technique of the drawing was as folllows : — The crania were oriented in 

 the Frankfort plane in the Kubuskraniophor, and then drawn by means of Martin's 

 dioptrograph in the three norma? specified. As the number of crania so dealt with 

 numbers 90, it follows that there are 270 life size tracings in the present work. 



In the various drawings the alveoli dentales are recorded in black, as are any 

 other cavities occurring in each specimen. The various anthropological points are 

 indicated by round black dots, and will be readily recognised by every craniologist- 

 They are labelled throughout as follows : — 



G is the glabella. 



Br, the bregma. 



L, the lambda. 



I, the inion. 



( ), the opisthion. 



Ba, the basion. 



P, the prosthion. 



N, the nasion. 



D, the dacryon. 



NS, the nasal spine.
