LETTER FROM SIR R. I.' MURCHISON. 167 



father and mother, who are delighted to have their grand 

 children. The week after next my younger sister, Leonora, 

 is to be married to Dr. Pertz, the King's librarian at Ber 

 lin. We like the marriage in every respect but one, that 

 it takes her so far away. He is expected here in a day or 

 two, and will stay in our house till the wedding takes place. 

 We were sorry not to see Mr. Gilman who brought your 

 letter, in consequence of our 'absence, but he was several 

 times at my father's. He had brought a letter of introduc 

 tion to Dr. Pertz at Berlin, and as he (Dr. P.) happened to 

 be in London, Mr. Oilman was introduced to him here. He 

 brought me the beautiful piece of amethyst quartz from 

 Dr. Gibbon of North Carolina. Might I ask you, dear sir, 

 kindly to give my best thanks for this, and explain why I 

 have been so slow in sending them. We have had a very 

 interesting tour, and enjoyed a charming climate all winter. 

 Sir Charles has profited much by the geology, and brought 

 here great materials for papers and memoirs. He is ex 

 tremely well too. 



I must conclude with our best compliments to Mrs. 

 Silliman, and kind regards to all your family in its vari 

 ous branches. 



Ever, very sincerely yours, 



MARY E. LTELL.

 We hope to reach St. Petersburg by the first of May, and 

 to be in the Ural Mountains, or on their flanks, in the first 

 week of June. I fear that our friend, Dr. Mantell, misled 

 you in writing to say that I was about to visit the United 

 States. This arose from Dr. Buckland having talked of
