PROCEEDINGS OF SECTION I. 



HEIGHT METERS. 



A simple form of height meter consists of a wooden rod 6 feet 

 (2 metres) in height and graded into quarter inches on one side 

 and centimetres on the other. On this sUdes a projecting wooden 

 arm set at right angles. This rod may be fixed in a vertical position 

 to a wall or door, or into a special platform 2 feet square and 3 inches 

 high. 



(P^-j^^B Short graduated rods 



' which do not reach the 



ground, but are fixed 

 on doors or walls, are fre- 

 quently used for measur- 

 ing stature by applying 

 a set square to their 

 front surface. Such 

 apparatus, though very 

 simple and cheap, is 

 liable to give inaccurate 

 measurements : first, 

 because it may not be 

 fixed at the correct height ; and, 

 secondly, because the surface to which 

 the set square is appUed may not be 

 vertical. 



Some weighing machines have height 



standard attached. (See Figs. 2 and 3). 



Schools where Sloyd is taught may 



find it interesting to make their own 



height meters. 



CALLIPERS. 



For the measurements of chest 

 diameters ordinary compass pelvimeter 

 (Fig. 5) will be found most convenient. 

 They are usually graduated in French 

 system. Martin and Collins' are good 

 makes.
