 scales in the lateral line. Tiie average number for Turkey Lake is 89.46 for the 

 left side, 89.74 for the right side; for Tippecanoe Lake, 87.69 for the left side, 

 87.45 for the right side. Fig. 1 represents the curves for the scales of the right 

 side. The continuous line represents the conditions in Turkey Lake, and the 

 broken line those of Tippecanoe Lake. It should be noticed that the entire curve 

 for Turkey Lake is two units to the right of that of Tippecanoe Lake, showing 

 that practically all the Turkey Lake specimens have a greater number of scales.
