of trilobites, brachiopods, and other invertebrates, totaling about 

 3,500 species — all from rocks which he identified as Silurian but 

 which have since been shown to include strata of lower and higher 

 periods. The first volume of his great series of publications, the 

 Systcjiie SUuricn du Centre dc la Bohemc, dealing with the trilobites, 

 appeared in 1852, and from then on he continued piiblishing until in 

 1881, 21 quarto volumes of text and plates had been issued. 



Barrande's collection is housed in the Narodni Museum, the 

 large, handsome building at the top of the Vaclavske Namesti (or 

 Wencelaus Place) which also contains the other natural history and 

 historical collections of Bohemia. (See figs. 8 and 9.) The special 

 division of the museum devoted to Barrande's collection, the Bar- 

 randeum, has been noted, but he is held in such high esteem at Prague 

 that, to further commemorate him, an extensive section of the Pale- 

 ozoic rocks along the Moldau River has been set aside to be available 

 to future students. The very interesting portion of this section show- 

 ing the greatly folded Silurian strata is known as the Barrandeum 

 Felsen, and, as shown in figure ii, has Barrande's name printed upon 

 it in large letters, visible tO' all travelers along the river, highways, and 

 railroads passing along the base of the clifif, which faces one of the 

 main traveled routes in Czechoslovakia. 



One of the most interesting exhibits in the Barrandeum is shown 

 in figure 10. At the top of a case devoted to personal mementoes of 

 Barrande may be seen views of his old workshop in Prague, and one 

 of the quarries he had opened for collecting fossils. The shelf below 

 contains the great series of quarto volumes forming the Systeme 

 Silurien du Centre dc la Boheiiie, while in the lower part of the case 

 are exhibited plates and text of two volumes together with his portrait, 

 geological hammer, collecting bag, and other mementoes. 



Leaving the charming city of Prague and its interesting people 

 with much regret at the completion of my work, I spent a few days 

 in Bavaria, particularly at the Alte Akademie at Munich, and in 

 France before sailing for New York on September 21. In all my 

 experience, this was my most successful field trip in making new 

 friends, in securing new information, and in adding study material to 

 the National collections.
