Coiichision of Mr. Roberts's Statement. 



71. What may be regarded as the most interesting features of the ■wrork 

 described in the preceding statement are the introduction of four new purely- 

 astronomical tides (the t-^vo evection-tides and the two variation-tides) and 

 the new luui-solar Helmholtz compound shallow-water tide. Further 

 investigation of the evection-tides is necessary and must lead to interesting 

 results, on account of the great discrepancies between the results shown in 

 § 61 above for the four years for which they have been calculated.
