Douanes, Mons. le Marquis de Vaulchier, and so extreme 

 the politeness of the principal and subordinate officers of the 

 Customs at Calais, that the importation and exportation of

It is needless to state, that on the establishment of an 

 observatory by a private individual in a foreign country, 

 many difficulties must be encountered. To Mons. Benjamin 

 Delessert, whose liberality in promoting every thing which 

 has science for its aim knows no bounds, I stand indebted, 

 amongst other things, for whatever comfort my observatory 

 afforded. 



From the members of the Royal Academy of Sciences of 

 Paris I uniformly received every possible attention, whilst 

 to Messrs. De la place, Arago, Bouvard, Humboldt, and 

 PoissoN, a residence of fifteen months has placed me under 

 obligations of no common order : they were received with 

 pride, and are remembered with gratitude. 



The Society have now before them, with few exceptions, 

 a re-examination of all the identified double and triple stars 

 described by Sir W. Herschel in the Philosophical Transac- 

 tions ; with the sentiments therefore of the illustrious author 

 of the Mecanique Celeste I will conclude — " Had the labours 

 of Sir W. Herschel been confined to this department of astro- 

 nomy, the discoveries he has made in it would have alone 

 conferred upon him an imperishable name."
