662 REPORT— 1893. 



tion, tlie mean circnmference of the chest will be obtained, which at the 

 corrected mid-grade would be 944 millimetres. 



Visio7i. — The power of vision was tested with Snellen's test-types 

 placed at a distance of 6 metres from the eye. Each eye was tested 

 separately ; while one eye was being tested the other was kept open, and 

 a black card was held over it to prevent the type being seen by it. 



The number of males who could read No. 6 type with both eyes at 

 6 metres, and whose sight was therefore normal, was 27 out of 55, or 

 49"1 per cent. Of these 17, or 309 per cent., were able to read No. 5 

 type at G metres. 



The females who were able to read No. 6 type with both eyes at 

 6 metres numbered 22 out of 49, or 44*9 per cent., and of these 13, or 

 26"5 per cent., were able to read No. 5 type at 6 metres. 



In a large number of cases in both sexes the vision in the two eyes 

 differed, that of one eye being more defective than that of the other. 



The time which could be devoted to each candidate was too short to 

 permit of any investigation as to the cause of the deficiencies in vision 

 being undertaken. 



Colour Sense. — The test-colours recommended in the Report of the 

 Committee of the Royal Society on Colour Blindness have been adopted in 

 testing the appreciation of colour. For this purpose a number of skeins 

 of coloured wools were added to wools of the colour given in the plate of 

 the just mentioned report, so as to increase the number of confusion 

 colours. Each candidate was given the three standard skeins and told 

 to pick out from the heap of coloured wools those that were like them in 

 colour. No case of colour blindness was found amongst either the males 

 or females. 



The table will give some idea of the variations of the diflFerent mea- 

 surements which have been obtained during the last three meetings of 

 the Association, and of the canon of proportion of the several parts 

 of the body. 



It wiU also enable anyone who has been measured in the laboratory 

 to find what his place is with respect to the corrected mean of each 

 measurement. If he is above or below the mean in any measurement, 

 by referring to that measurement in the report he will be able to ascer- 

 tain further particulars with respect to his position. The 25th, 50th, 

 and 75th grades are the positions which would be held by the 25th, 50th, 

 and 75th man if a hundred men were marshalled in a row, beginning 

 from the smallest up to the greatest, with respect to the particular 

 measurement.
