MEASUIiF OF ItFSFMRLAXOE OF FIRST COUSINS 



25 



(iii) Length of First Joint of Index and Little Fingei 



See Figure (iii). 



Close the fist (thumb outside) and 

 thumb uppermost and spanner hori- 

 zontal — the lengths from knuckle to 

 first joint of (a) the Index Finger ; 

 (b) the Little Finger. The outside of 

 first joint is put against the tixed jaw 

 of the spanner, and the movable jaw 

 is brought against the outside of the 

 knuckle with gentle pressure. Clamp 

 and read as before, making two or three 

 trials. 



All the measurements should be 

 made with care. The above instruc- 

 tions are intended for self-measurement, 

 but it is easy for one observer to measure 

 both of a pair of cousins, or him or herself and then the cousin 



Fig. (iii). 



VI. — In case of any difficulty, please apply at once to Professor Karl Pearson, 

 University College, London, W.C. The Box and papers should not be kept longer 

 than a month, unless the observer finds it possible to undertake a large series of 

 cousins. About a thousand pairs of cousins of each type, 10,000 in all, will be 

 required. Hence every co-operator will appreciate the necessity for rapid circulation 

 of the boxes, of which only a limited number can be provided. • 



The name of the observer and address should always be given, in case it is 

 necessary to ask questions as to any special measurement or observation. The 

 cousins, if it be preferred, may be simply denoted by the initials of their christian 

 and surnames, as these will suffice for the observer to identify them*. 



* Spanners and schedules are still (November, 1907) being issued, 

 measurements will be gratefully accepted.
