476 The Faraday Centenary. [June 17, 



Moreover, you have kindly invited me to attend to the lecture, 

 which is to be delivered the 17th June at the very place where the 

 celebrated explorer of physical truths has worked. 



Unhappily for me I cannot see any possibility for my going to 

 London this summer, and therefore I allow me to beg you to be my 

 interpreter before the Royal Institution and express my most humble 

 thanks for the great honour the Royal Institution has bestowed on 

 me. 



At last I permit me to express my warmest felicitations for the 

 prosperity of the Royal Institution, and hope that the Institution in 

 the future may be able to continue her noble work to support many 

 such heros of science as the celebrated Michael Faraday, whose epoch- 

 making discoveries, deep thoughts and ingenious presentiments now 

 fructify the scientific labours everywhere and in the greatest manner 

 contribute not only to the successful progress of science, but also to 

 the happiness and welfare of the whole humanity. 



I am, Sir, your most obedient servant, 

 Rob. Thalen, 

 Prof, at the University in TJpsala, 



St. Petersburg, May 14/26, 1891. 

 Most honoured Sir, 



In answer to your information of my being elected Member of the 

 Royal Institution of Great Britain in connection with the Centenary 

 of the birth of Faraday, I can only express my heartfelt thanks for 

 the honour of being admitted to the circle of the highly esteemed, 

 universally renowned English men of science. The engagements and 

 duties, which I took on me, make it impossible for me to leave Russia 

 and come personally amongst you at the ejid of June or in July. 

 These are the reasons why I must beg you, most honoured Sir, to be 

 so kind to transmit my sincere and profound gratitude to the 

 Members of the Royal Institution, and my welcome to the memory of 

 Michael Faraday as from one who is a devoted admirer of his glorious 

 name. 



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



D. Mendeleeff.
