ON THE WORK OF THE ANTHROPOMETRIC LABORATORY. 623 



Pull. — The mean strength of pull of both hands is in the males at 

 the 25th grade 60-8 lbs. ; at the 50th, 68-4; at the 75th, 74-9 ; 'Q' is 

 7, and the corrected mean is 67'8 lbs. In the females it is at the 25th 

 grade 32 lbs. ; at the 50th, 36 ; at the 75th, 43-3 ; ' Q ' equals 5'6, 

 and the corrected mean is 37-6 lbs. In 32 cases out of 71 in the 

 males the pull with the right hand is the stronger, in 33 the left is 

 the stronger, and in 6 cases the two hands are of equal strength. In 

 2 7 females the right hand is the stronger in 9 cases, the left in 14, and in 

 6 the two hands are equal. 



Vital Capacity of Lungs. — In the males the vital capacity at the 

 25th grade is 188 cubic inches ; at the 50th, 221 cubic inches ; at 

 the 75th, 254'5 cubic inches ; ' Q ' equals 33-2, and the corrected mean 

 is 221'2 cubic inches. In the females it is at the 25th grade 101'4; 

 at the 50th, 125-5 ; at the 75th, 148-8 cubic inches ; ' Q ' equals 23-4, 

 and the corrected mean is 124*8 cubic inches. The vital capacity of 

 the chest was ascertained by means of Stanley's spirometer, kindly 

 lent for the meeting by the manufacturers, Messrs. Tallack & Co., of 

 28 Hatton Garden, London, to whom the Committee express best thanks 

 for having placed at their disposal, for two consecutive years, this very 

 excellent instrument. 



Circumference of the Chest. — This dimension was only ascertained on 

 the males. At the 25th grade, during forced inspiration, it measures 

 932 millimetres ; at the 50th, 970 millimetres ; at the 75th, 1,017 

 millimetres ; ' Q ' equals 42, and the corrected mean 976 millimetres. 

 The difierence between forced inspiration and forced expiration is at the 

 25th grade 41 millimetres ; at the 50th, 52 millimetres ; at the 75th, 

 69 millimetres ; ' Q ' is 14, and the corrected mean 55 millimetres. By 

 subtracting half of this latter sum from the corrected mean circumference 

 of the chest during forced inspiration, we get 968 millimetres as the 

 Liirth of the chest when the lungs are midway between forced inspiration 

 Mild expiration. 



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

 placed at a distance of 6 metres from the eye. The number of males who 

 could read No. 6 type with both eyes (each eye being tested separately) 

 was 38 out of 73, that is 52 per cent., and 14 of these were able to read 

 No. 5 at 6 metres. Of the females 13 out of 26, or 50 per cent., had 

 normal vision ; that is to say were able to read No. 6 test-type at 6 

 metres ; indeed, all but 4 of them were able to read No. 5 at 6 metres. 

 In several cases the vision with one eye was normal, while that of the 

 other was more or less defective. 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. — This was tested by asking the candidate to pick out 

 first the greens and afterwards the reds from a series of cards which con- 

 tained the various confusion coloui-s for green and red blindness, and 

 several other colours. Three of the males were found to be colour-blind. 



For purposes of comparison a table of the corrected means of the 

 different measurements dealt with in this report has been made out, and 

 placed side by side with the corresponding figures obtained from the 

 laboratory in the previous year. 



The Committee desire to be reappointed, and to have a sum of 51. 

 again placed at their disposal.
