Erysimum odoratum and crepidifolium are very nearly allied, and 

 as here found, both smell equally sweet. Even the character depend- 

 ed upon by Koch — the smooth angles of the pod in the first-named 

 species, is not to be taken without some allowance ; and in the last, 

 as exhibited at Muggendorf, the angular nerve is sometimes greener 

 and less hairy than the flat faces of the pod. The specimens from 

 Kreuznach seem to exhibit this character more absolutely, and I 

 should have been inclined to doubt whether all my Muggendorf 

 plants did not belong to E. odoratum, if Koch had not called them 

 crepidifolium. 



Erlaiigen will shortly be very accessible to the English traveller, as 

 the rail-road now in progress from Bamberg to Augsburg passes 

 through it. There are steam-boats from Frankfort to Wiirzberg, so 

 that the only part of the journey to be performed in the slow old- 

 fashioned plan is from Wiirzberg to Bamberg, and this I think cannot 

 continue long. They talk of a rail-road from Nuremberg to Ratisbon. 

 There is already a canal. 



From Erlangen to Neumarkt the soil is sandy, nearly level, and 

 abounding in pine-forests. Beyond Neumarkt (where there is an ex- 

 cellent inn), we got upon hills of the Jura limestone, and there are a 

 few beautiful spots, and tempting slopes, which the botanist would 

 like to examine ; but on the whole, it is a country of little interest 

 till we descend towards the Danube and approach Ratisbon, where 

 some very beautiful valleys reminded me of Muggendorf. Above 

 Ratisbon, and on one side also of the Danube, for two or three miles 

 below, the valley is bounded by rocky hills of the Jura limestone, on
