414 APPENDICES 



When I entered Bunsen's Laboratory in the Easter of 1856 as a novice 

 of twenty years of age the sight of the wealth of chemical appliances was 

 so overwhelming that I nearly burst into tears. Bunsen appeared to me 

 like a being from another world, and Roscoe, his co-worker, who had 

 taken his degree two years before, as one sent from a distant sphere. To 

 be their equal was the highest object of my ambition. How am I to des- 

 cribe the delight that seized me when Bunsen proposed, in my second 

 Semester, as an acknowledgment on his part of good progress made, 

 that I should work on " Idio-Chemical Induction," a theme, in some 

 measure, complementary to your photo-chemical researches ? My anticipa- 

 tions were not realised, but your investigations made a deep impression 

 on my mind and had a lasting influence upon my subsequent life. 



And at a later period of your activity, when your work was receiving 

 its due acknowledgment in your own country, your example again 

 exerted a profound influence upon me. It was in attempting to raise the 

 character of the instruction in Analytical Chemistry in our German 

 Universities by the foundation of the " Verband von Laboratoriumvor- 

 standen an deutschen Hochschulen" that I was swayed by the example 

 of the persistency and energy which you displayed in the cause of reforms 

 of Technical Education in England. 



Thus, my highly-honoured Friend, twice during my life have you 

 influenced my action and helped me to find the right path. My con- 

 gratulations to you on this day of your jubilation spring therefore from a 

 grateful heart, and as such will, I trust, not be unwelcome.

HIGHLY HONOURED COLLEAGUE, DEAR FRIEND AND FELLOW- 

 STUDENT, 



To-day, when so many of your Colleagues, Scholars, and Friends are 

 tendering you their congratulations, you may not be unmindful of the 

 voice of one who is far away, but who has been privileged to follow the 

 development and outcome of your career for fully fifty years. Only a few 

 remain from that happy time, but for that very reason their voices may 

 have the greater weight. 



It was in the Winter Semester of 1853-54 that I came to Heidelberg 

 to listen, in the class-rooms in the old cloisters, to the teaching of our 

 revered Master, Bunsen, at the end of which Semester you took your 

 Degree. This occurred soon after the beginning of that brilliant period 

 of the academic activity of that immortal man which attracted the 

 enthusiastic youth of the whole world. A kind fortune enabled you to 

 work under his direction longer than many of us. But that was not mere 

 chance. Among the great number of his scholars the Master soon 

 recognised one of the most gifted, and had selected him as a well-trained 

 and trustworthy assistant. He was not deceived in his anticipations. 

 What he expected, you have fulfilled. The loud acclaim which is 

 rendered to you to-day only confirms what Bunsen had foreseen and pre- 

 dicted. In April 1856, when I returned to Heidelberg from Munich, 

 where I had listened to Liebig and worked with Jolly, you and I were 

 colleagues in the new Laboratory, then just finished, and where later on 

 you were a frequent and welcome guest. 



In June 1856, we the senior pupils in Bunsen's laboratory were 

 photographed together. In this picture, which lies before me, I see the
