authors, British and foreign. Even the astronomical 

 part was difficult, for I had to translate analytical 

 formulas into intelligible language, and to draw 

 diagrams illustrative thereof, and this occupied the 

 first seven sections of the book. I should have been 

 saved much trouble had I seen a work on the subject 

 by Mr. Airy, Astronomer-Royal, published sub- 

 sequently to my book. 



My son, Woronzow Greig, had been educated at 

 Trinity College, Cambridge, and was travelling on 

 the Continent, when Somerville and I received an 

 invitation from the Principal, Dr. Whewell, to visit 

 the University. Mr. Airy, then astronomer at 

 Cambridge, now Astronomer-Royal at Greenwich, 

 and Mrs. Airy kindly wished us to be their guests ; 

 but as the Observatory was at some distance from 

 Cambridge, it was decided that we should have an 

 apartment in Trinity College itself ; an unusual 

 favour where a lady is concerned. Mr. Sedgwick, 

 the geologist, made the arrangements, received us, 

 and we spent the first day at dinner with him. He 

 is still alive* one of my few coevals either in 

 Cambridge or England. The week we spent in 

 Cambridge, receiving every honour from the heads 

 of the University, was a period of which I have' 

 ever borne a proud and grateful remembrance. 



* Professor Sedgwick died shortly after my mother.
