DESCENT AND EARLY MANHOOD 15

 Wohler, his lifelong friend, gave him, amongst other 

 tokens of regard, the portfolio used by Berzelius and 

 himself for carrying notes and manuscripts during 

 their geological and mineralogical tour through Sweden 

 and Norway in 1824. 



On 1 July 1824, Friedrich Wohler and Christian 

 Retzius set out for Skimskatteberg, the estate of 

 Hisinger the chemist, where they found Berzelius 

 awaiting them. There they spent a week, making 

 short excursions in the neighbourhood with Berzelius 

 and Hisinger. In the middle of July they journeyed to 

 Helsingborg to meet the Brongniarts Alexandre, 

 the chemist and mineralogist, and his son Adolphe, 

 the botanist. Here they found Baron Wrede the phys- 

 icist, Oersted the founder of the science of electro- 

 magnetism, and Sir Humphry Davy the natural phi- 

 losopher. At Lund they were welcomed by Nilsson the 

 naturalist, and Agardh the botanist, and at Chris- 

 tiania by Hansteen the mathematician and astrono- 

 mer, Esmark the mineralogist, and Steffens the Natur- 

 philosoph. After an absence of two months, the party 

 - which had included Berzelius, the Brongniarts, and 

 Wohler returned to Stockholm. It does not appear, 

 as Goessmann supposed, that Arfvedson, the mineralo- 

 gist, was one of the party, though earlier the latter 

 made a short journey to the island of Uto, in the Baltic, 

 in company with Berzelius, Hisinger, C. Retzius, and 

 Wohler.
