ALCOHOL ON HAND AND EYE COORDINATION 191 



probably would have showed coordination characteristics very 

 different from those obtained, if he had been tested in the eve- 

 ning. Unf ortunately , the reactors were not tested after the ' 'final' ' 

 sheet, and their reports next day are the basis of the description 

 of the effects of the twenty hours following the tests. The 

 relative futility of tests of single functions, even if several are 

 tested in succession, is illustrated by reactor B. Although 

 marked deterioration is shown in the coordination, it is not a 

 sufficient index of the degree of intoxication. Yet this test, as 

 our previous work shows, catches the deterioration more defi- 

 nitely than most mental or psychophysical tests. 



The test-sheet itself proves to be a good one, and it can very 

 usefully be applied to other problems. Slightly different forms 

 are being prepared for use with children. 



NOTE: Since the above was written, I have discovered in a 

 recent monograph on tobacco effects, a somewhat similar form, 

 ascribed to Columbia, and have just obtained a sample of this 

 test. The Columbia form has five pathways, each ^ inch wide, 

 with twenty-seven rectangular turns, with a total distance from 

 right to left of 5J inches. Only the two lines enclosing the 

 pathway are printed. I believe the additional lines on my sheet 

 are an advantage. 



The form I have designed is of course a result of working with 

 Whipple's star figure, Franz 7 Maze tests, and the Porteus tests.
