was obliged to make to order and provide the tools and 

 materials which were continually wanting, I may say by 

 wholesale. 



The discovery of the Georgian satellites caused many 

 breaks in the sweeps which were made at the end of 1786 

 and beginning of 1787, by leaving off abruptly against the 

 meridian passage of the planet, which occasioned much 

 work, both in shifting of the instrument and booking the 

 observations. Much confusion at first prevailed among 

 the loose papers on which the first observations were 

 noted, and some of them have perhaps been lost ; for I 

 remember several configurations of the situation of the 

 satellites having been made by Sir William Watson and Mr. 



Marsden, and only one could be found

That the discovery of these satellites must have brought 

 many nocturnal visitors to Slough may easily be imagined^ 

 and many times have I listened with pain to the conversation 

 my brother held with his astronomical friends when quite 

 exhausted by answering their numerous questions. For I 

 well knew that on such occasions, instead of renewing his 

 strength by going to rest, that there were too many who 

 could not go on without his direction, among whom I often 

 was included, for I very seldom could get a paper out of his 

 hands time enough for finishing the copy against the 

 appointed day for its being taken to town. But considering 

 that no less than seven papers were delivered to the Royal 

 Society in 1786-1787, it may easily be judged that my 

 brother's study had not been entirely deserted. I had 

 always some kind of work in hand with which I could 

 proceed without troubling him with questions ; such as the 

 temporary index which I began in June, 1787. Some 

 years after, the index to Flamsteed's observations, calculat- 

 ing the beginning and ending of sweeps and their breadth,
