The experiments from No. 1-51 to No. 172 were taken with the lengthened 

 run. The acceleration with the larger weight was nearly one second every 

 five and twenty feet ; hence the difference when the quantities are compared 

 with Position 1. The unseasonable weather made it necessary to stop the 

 above experiments and commence those in which the model was entirely im- 

 mersed.
