RECORD OF FAMILY FACULTIES. 



accessible for testing it in different persons ; there are no anthropometric 

 laboratories as yet in existence to which any one may go, and on payment 

 of a small fee have all his faculties measured and registered by the 

 various ingenious appliances known to modern science. We must therefore 

 be content for the present with such definite facts bearing on the keenness 

 or imperfection of the various senses as may have been incidentally 

 observed. 



(n) The mental powers, like the bodily ones, must be measured by 

 achievement ; relatively as in competition with others, or absolutely by

 other people, being on freer terms with their professional brethren. 



(14) Minor ailments. A knowledge of these gives considerable help 

 towards understanding the " constitution " of a person, and it is a
