trial record was fourteen, and the time and distance records 

 for the rat making this record were also low. The lowest time 

 record, as well as the lowest distance record was made by a rat 

 finishing in twenty trials. The rat requiring the largest number 

 of trials (112) had a time record but little higher than one which 

 required only thirty-four trials, while its distance record was 

 next to the highest. The highest time record was that of a 

 rat which finished in one hundred seven trials, with the next 

 to the highest distance record, the highest distance record by 

 one finishing in twenty-seven trials, whose time was consid- 

 erably above the average.
