his sovereign. To be used on such occasions only, he kept an "order'' 

 coat, a "frack" or tail coat, upon the breast of which he had stitched 

 as many of the stars and crosses as*it would comfortahlv hold Dur- 

 ing the jubilee the Grand Duke held a court in the castle, and pre- 

 sentations were made. Bunsen, who had already paid his devoirs to 

 the Grand Duke's party, expressed his unwilfingness again to go 

 through the necessary formalities, but after some persuasion on rny 

 part he consented, hoping, as he said, to conceal himself behind the 

 crowd of officials and dignitaries of all sorts who thronged the hall in 

 which the royalties were assembled. So we walked together up to the 

 castle in evening dress, as the custom is, Bunsen wearing his "orders." 

 The streets through which the procession of magnates was to pass were 

 filled to overflowing by a good-natured crowd, no military or even 

 police being present to clear the way, so as the royal carriages came 

 up the steep road leading to the castle, a block occurred, and, as liu-k 

 would have it, that containing the Grand Duke, the Duchess, and the 

 Prince of Prussia came to a standstill at the exact point where Bunsen 

 and I stood endeavoring to make our way through the crowd. The 

 Duke at once recognized the Geheimerath, and beckoned him to come 

 to the carriage, and there and then they had a friendly chat, and I had 

 the honor of being presented. As soon as the cortege moved on I 

 had a good laugh at Bunsen, who, endeavoring to escape from all 

 notice and attention, was entrapped in this amusing fashion. 



Let me next endeavor to give you a picture of the master working in 

 his laboratory. 



When he first came to Heidel})erg, in the sunnner of lS,o"i. Bunsen 

 found himself installed in Gmelin's old laboratorv. This was situated 

 in the buildings of an ancient monastery, and there we all worked. It 

 was roomy enough; the old refectory was the main laboi-atory; the 

 chapel was divided into two; one half became the lecture room and 

 the other a storehouse and museum. Soon the number of stmlents 

 increased and further extensions were needed, so the cloisters were 

 inclosed by windows and working benches placed Ixdow them. Beneath 

 the stone floor at our feet slept the dead monks, and on their tomb- 

 stones we threw" our waste precipitates! There was no gas in Heidel- 

 berg in those days, nor any town'swater supply. We worked with 

 Berzelius's spirit lamps, made our coml)ustions with charcoal, boiled 

 down our wash waters from our silicate analyses in large glass glolies 

 over charcoal fires, and went for water to the i)ump in the yard. 

 Nevertheless, with all these so-called drawbacks, we wereal)le to work 

 easily and accurately. To work with Buns(Mi was a real i)leasure. 

 Entirely devoted to his students, as they were to him. he sp«'nt all day 

 in the laboratory, showing them with his own hands how l)est to carry 

 out the various operations in which they were engaged. You would 

 find him with one man showing tiie new method of wii-shing pn-cipi-
