MATHEMATICAL DRAWING INSTRUMENTS 



Arranged at first in cheap sets, beginners seldom requiring separate instruments ; each 

 instrument, however, may be had separately, both of the best and plain kinds, care is 

 taken to combine with each set only such parts as are most useful in proportion to the 

 price ; this rule extends to the finest sets and instruments enumerated ; the arrange- 

 ments of joints and needle points being of the latest improved, and the pens such only 

 as are found to give the highest satisfaction.
