 Eome, May 26, 1891. 

 Dear Sir, 



I have received your esteemed letter of the present month in- 

 forming me of the great honour that has been conferred upon me by 

 naming me an honorary member of the Eoyal Institution of Great 

 Britain, and inviting me to attend the scientific gathering to celebrate 

 Faraday's Centenary. 



I fully appreciate the distinction, and my wish would be to 

 attend the said gathering, but I cannot come to a determination until 

 June, and I must know the exact date of the meeting. 



I must in the meanwhile ask you to kindly convey my best 

 wishes for the Institution, and pray accept the respectful regards of 

 your obedient servant 



PlETRO TaCCHINI. 



University, Copenhagen, 

 May 22, 1891. 



Sir, 



Having by your letter been informed of my being elected an 

 honorary member of the Eoyal Institution of Great Britain in 

 occasion of the Centenary of the birth of Michael Faraday, I beg 

 you, Sir, receive my sincere thanks for this acknowledgment of my 

 labours and the honour thereby shown not only myself, but also my 

 little hardly treated native country. 



Of course I would have much gratification in attending on your 

 meeting in London to receive the Diploma personally, but unfortunately 

 my health for the moment is not quite to be relied upon for making 

 the said long journey. 



I have the honour to be. Sir, your obedient servant, 



Julius Thomsen. 



Upsala, June 2, 1891. 

 Dear Sir, 



I have the honour to acknowledge the receipt of your estimated 

 letter, by which you have announced to me that, in connection with 

 the Centenary of the birth of Michael Faraday, the Eoyal Institution of 

 Great Britain in London has conferred on me the grand honour to be 

 elected an Honorary Member of the Institution.
