in 1844. He also came into possession of some of Geyer’s collections, 
as it is definitely stated that they had been deposited in the Engelmann 
herbarium. 
In 1841 Géyer went with Fremont to the Des Moines River in Iowa 
territory, where he found a number of new plants. In 1842 he ex- 
plored the upper Illinois territory and formed the herbarium which 
was first offered for sale. In 1843 he began the journey from Missouri 
to the Pacific coast, lasting through the years 1843 and 1844. He ex- 
plored the northwestern country very extensively and penetrated to 
hitherto inaccessible places by accompanying missionary trains on their 
visits to the different Indian tribes. He finally reached Fort Van- 
couver, and from there sailed on November 13, 1844, for England, go- 
ing by way of the Sandwich Islands and Cape Horn. He arrived in 
England May 25, 1845, and spent some months at Kew, working over 
his collections and sorting out small lots of plants to sell. A large 
part of his profits from such sales was used in defraying expenses 
caused by a sickness brought on by his previous hardships. In Sep- 
tember, 1845, he again returned to his home in Saxony, after an ab- 
sence of eleven years. At first he entered the employment of head-gar- 
dener Lehman in Dresden, and later in the Royal Botanical Garden. 
His wanderings had shown him the value of a home, and on August 
24, 1846, he married Miss Emma Schulze. Besides his duties for the . 
garden he taught students the English language, his pupils coming 
from every class in Meissen. Geyer also took a prominent part in the 
local society for the advancement of science. During the last three 
years of his life he was editor of Chronik des Gartenwesens und 
Feuilleton der Isis, a periodical published at Meissen on the first and — 
fifteenth of the month, from January 1, 1851, to December 15, 1853. 
Geyer’s death occurred just before the end of the third volume, and it 
was discontinued with the third volume. While in no wise neglecting 
his duties at the garden, he came in written communication with the 
prominent botanists of the time and rounded out his collections. 
Heart disease troubled him considerably in his latter days and finally 
caused his death on November 21, 1853 
In 1835 a physician, George Hrigelmann by name, settled in St- 
Louis and soon built up a lucrative practise. During his spare mo- 
ments he worked upon botanical problems, and before long he had 
established a reputation among botanists such that at his death he was 
ranked among the foremost of botanical workers.
