read them all, but cares little to see the plants themselves; in short, he is a true closet student. He has a large herbarium, composed in great part of plants purchased or received as gifts. The other, Professor Hochstetter, is an odd little man, stepping briskly about in his high boots, and having always a half suppressed smile on his hips whenever he takes the pipe from between his teeth. A very good man, however, and extremely obliging; he offered us every civility. As we desired not only to make their acquaintance, but to win from these botanists at least a few grasses, we presented ourselves like true commis voyageurs, with dried herbs to sell, each of us having a package of plants under his arm,--mine being Swiss, gathered last summer, Braun's from the Palatinate. We gave specimens to each, and received in exchange from Steudel some American plants; from Hochstetter some from Bohemia, and others from Moravia, his native country. From Esslingen we were driven to Goeppingen, in the most frightful weather possible; it rained, snowed, froze, blew, all at once. It was a pity, since our road lay through one of the prettiest valleys I have ever seen, watered by the Neckar, and bordered on both sides by mountains of singular form and of considerable height. They are what the Wurtembergers call the Suabian Alps, but I think that Chaumont is higher than the loftiest peak of their Alps. Here we found an old Heidelberg acquaintance, whose father owns a superb collection of fossils, especially of shells and zoophytes. He has also quite a large collection of shells from the Adriatic Sea, but among these last not one was named. As we knew them, we made it our duty to arrange them, and in three hours his whole collection was labeled. Since he has duplicates of almost everything, he promised, as soon as he should have time, to make a selection from these and send them to us. Could we have stayed longer we might have picked out what we pleased, for he placed his collection at our disposal. But we were in haste to arrive here, so we begged him to send us, at his leisure, whatever he could give us. Thence we continued our journey by post, because it still rained, and the roads were so detestable that with the best will in the world we could not have made our way on foot. In the evening we reached Ulm, where, owing to the late hour, we saw almost nothing except the famous belfry of the cathedral, which was distinctly visible as we entered the city. After supper we continued our journey, still by post, wishing to be in Munich the next day. I have never seen anything more beautiful than the view as we left Ulm. The moon had risen and shone upon the belfry like broad daylight. On all sides extended a wide plain, unbroken by a single inequality, so far as the eye could distinguish, and cut by the Danube, glittering in the moonbeams. We crossed the plain during the night, and reached Augsburg at dawn. It is a beautiful city, but we merely stopped there for breakfast, and saw the streets only as we passed through them. On leaving Augsburg, the Tyrolean Alps, though nearly forty leagues away, were in sight. About eighteen leagues off was also discernible an immense forest; of this we had
