From these computations follows that the maximum velocity in* 

 the canal on the side of the Pacific, due exclusively to the tidal 

 motion, will amount to 1.17 M. Supposing that there might be 

 some difference between the mean sea level of the Atlantic and the 

 Pacific and that this difference might amount to 0.50 M., the com- 

 mission concludes that the maximum velocity might then increase to 

 1.26 M. The commission thus finally arrives at the conclusion referred 

 to above. 



§ 4. The two first suppositions on which the computations are 

 based will probably not seriously deviate from the truth. For they 

 are, at least partially, confirmed by what is observed on the Suez-canal. 



The commission further points out, that the formula for the 

 velocity of propagation of the tidal wave, which has been derived 

 in the supposition that the amplitude of the tide is relatively small 

 as compared with the depth of the water, leads to results which, for 

 the Suez-canal, agree closely with the observations. For the formula
