xxvi GENERAL BUMMARY OF SCIENTIFIC AND 



The following table presents some of the recently pub- 

 lished values of the solar parallax: 



From Cornu's experiments, using Bradley's aberration 



constant parallax = 8. 88" 



From Foueault's experiments, using Struve's aberration. 



From opposition of Mars, 18G2 



From Le Verrier's discussion of transits of Venus, 17GI 



and 1769 



From Le Verrier's discussion of meridian observations 



of Venus 



From Galle's discussion of the observations of Flora. . . 

 From Puiseux's preliminary computation of transit of 



Venus observations, 1874 " =8.85" 



To which we may add from NewcomVs " Investigation of 

 the Distance of the Sun :" 



From lunar equation of the earth parallax = 8. 81" 



From parallactic inequality of the moon " =8.84" 



From Fowalky's discussion of transit of Venus, 1760.. " =8.86" 

 From meridian observations of Mars, 1862 " =8.84" 



Mr. Marth calls the attention of possessors of large tele- 

 scopes to the ease with which they may make observations 

 of the movements of the satellites of Saturn and Jupiter, as 

 he is anxious that observations should be made for the im- 

 provement of the theory of the satellites of Saturn.

 vious list are as follows :
