 results obtained in the proposed observatory shall have justified the extension

 stations may be added, provided with the moderate equipment needed to 

 multiply the chances of that continuity of observation which it is so desirable 

 to secure.

 bringing this important question under the notice of a nobleman whoso 

 scientific acquirements render unnecessary any lengthened argument to prove 

 that the proposed observatory is likely to redound to the honour of England, 

 and to materially assist in the advancement of Natural Knowledge.
