Finger-print Apparatus. 



Finger-print appjiratus consists of (1) a polished inetal plate, about 

 4 inches by 12 inches, mounted on a wooden block about an inch thick ; 

 (2) a roller for distributing the ink ; (3) finger-print ink in collapsible 

 tube ; (4) a good supply of benzoline ; (5) a small reading glass. This 

 apparatus may be obtained from Aston ct Mander. 



The polished metal plate is placed on a stand or table about 4 feet in 

 height. About six drops of ink should be squeezed from the tube along 

 the centre of the plate at intervals, and then thoroughly rolled until an 

 evenly coated film of ink is spread over the whole surface of the plate. 



To obtain an impression each of the subject's digits should be placed 

 with one side in contact with the inked plate and rolled on the plate till 

 the whole surface, up to the first joint, is inked. The impression is taken 

 by repeating the rolling operation on a sheet of paper. 



HAIR AND EYE C0L0UR8. 



INrEODUCTIOX, 



A considerable number of schemes of classification of hair colours and 

 eye colours have been published, but it is only necessary to consider those 

 that have been used to carry out extensive pigmentation surveys. Of 

 these there are only two that appear to be important — namely, the 

 scheme of Virchow and the scheme of Beddoe. 



Virchow's scheme has been adopted more or less completely in carry- 

 ing out a survey of about ten million children in Germany, Austria, 

 Switzerland, Belgium, and Beddoe's has been generally adopted in ob- 

 servations made in the British Isles. These schemes are not in com- 

 plete agreement, and it is desirable that a scheme should be devised that 

 should be comparable with both. This is the chief object aimed at in the 

 scheme drawn up by the Anthropometric Committee. Tables are given 

 below showing the relation of the three schemes — namely, that of Virchow, 

 of Beddoe, and of this Committee. 



It is desirable also that a set of standai'd colours, representing the central 

 colour of each category, should bo determined. These standards should be 

 permanent and should be ea.'sily obtainable by any person wishing to make 

 exact observations on hair or eye colours. For less exact observations tiie 

 names of the colours given in each category will suffice. In large survovs 

 carried out by school teachers or other officials the cost of supplying 

 standard colours to each observer may be prohibitive, but it must not be 

 forgotten that there is a considerable amount of inconsistency between 

 diflerent observers when colours are determined by the names only. The 

 Committee strongly recommend the use of standard colours whenever 

 possible. 



Pia:MENT.VTIO>^ STANDAKDS AND METERS. 



Standard coloured glasses representing the central colours of each 

 category of hair colours and eye colours have been prepared by and can 

 be obtained from Mr. Lovibond, of the Colour Laboratory, Salisbury. 

 These standard glasses are used for determining the colour of any given 

 sample of hair or of eyes in the Pigmentation Meter, a modification of 

 the Lovibond tintometer, adapted by J. Gray to observations on hair,
