136 FIRST JOURNEY IN EUROPE, 



of use. His other matters I will take in hand, but 

 he must not expect $20 to procure a doublet ^th 

 inch focus, two micrometer glasses, and a case of dis- 

 secting instruments. I have some engagements before 

 me with microscopical people, and when I get from 

 them all the information I can, I will set about these 

 affairs more understandingly. . . . 



Saturday evening, February 9. I have been en- 

 gaged nearly the whole day upon the herbarium you

 I hope another day will do it, but am not certain. 

 I shall still require about three days more at the Brit- 

 ish Museum, two at the LinnaBan Society, and one at 

 Lindley's. An evening or two at Benthain's will suf- 

 fice to certify his LabiataB, Scrophularina3, etc. I must
