JOACHIM BARRANDE. 



II., niS SCIENTIFIC WOKK. 



TiiK iulluence of Barrande upon science in 

 this couutiy and tbroughoiit Europe has been 

 of the first importance ; and he lias done much 

 for the rei)ulatiou of manj- of our investigators 

 by his careful attention to their works, and his 

 respectful quotations. He recognized the work 

 especiall}- of Dr. E. Emmons, and gave him 

 the credit of being the discoverer of the pri- 

 mordial fauna, which Emmons had previously 

 published as being in the Taconic system. 

 Barrande thus ranged himself, during the cele- 

 brated Taconic controversy, on the side of Dr. 

 Emmons, and his principal supporter in this 

 country. Professor Jules Marcou. One of IVf. 

 Barrande's most remarkable discoveries related 

 to what he has called 'colonies.' According 

 to him, certain characteristie fossils appeared 

 sporadically in the faunas preceding those to 

 which they properly belonged ; and he deduced 

 from this the result that two faunas having 

 some identical species, but existing in different 

 parts of the world, were not necessarily contem- 

 poraneous because of this fact, but might, in- 

 deed, be very distinct in age. These views are 

 strongly supported by Professor Jules Marcou 

 in this country, who states that he has dis- 

 covered similar colonies in the rocks of the 

 Taconic, underlying the Potsdam at Swanton 

 and Phillipsburg ; and is opposed principally 

 by English auiiors upon the grounds that the 

 evidence was stratigraphicall^' defective. Bar- 

 rande's reply to this, which he was preparing 

 at thrf time of his death, has not yet been pub- 

 lished. The theory has the support of the 

 geologists of Vienna, especially llaidiuger, 

 director of the Imperial museum, whom Bar- 

 rande quotes upon the titlepage of each of his 

 books upon the ' colonies.'

imbrications of this voluminous and accurate 

 writer must have reached nearlj- a hundred. Of 

 these, between seventy and eighty were made 

 to learned bodies, and from sixteen to twentj' 

 were pamphlets and books of octavo size : some 

 of these were abridgments of his larger vol- 

 umes. In the latter series, his 4ttcdes, extracts, 

 etc., he published over three thousand pages 

 and twenty-nine plates. Of the.se, his ' Cephal- 

 opodes, etudes gen(5rales,' was the most impor- 

 tant to the general student. His grand work, 

 the publication of which was begun in 1852, 

 and is not yet finished, has already reached, 

 as we have said, the number of twentj"-two 

 quarto volumes. These treat of the Trilobites 

 and Crustacea, 1,582 pages, 84 plates ; Cepha- 

 lopoda, 3,600 pages, 544 plates ; Brachio- 

 poda, 226 pages, 153 plates ; Acephala, 342 

 pages, 361 plates ; and he announces as having 

 alreadj- completed over 100 plates of the Gas- 

 teropoda, which have not ^et appeared. This 

 makes the enormous number of 5,750 pages of 

 text in quarto, and 1,148 plates already issued, 

 which we estimate as containing .about eighteen 

 thousand figures of fossils of the finest exe- 

 cution. 



Barrande published large editions of his 

 smaller works, which he distributed with a free 

 hand to many institutions and scientific men ; 

 but of his larger works, the edition, probabl}' 

 on account of the expense, was limited to two 

 hundred and fifty copies. The larger number 

 of these he also gave away to scientific insti- • 

 tutions and to individu.il geologists, and it is 

 estimated that he did not receive in return as 

 much as the actual cost of three of 'the large 

 volumes. 



The Gasteropoda, lOchinodcrmata, Bryozoa, 

 and miscellaneous fossils still remain unpub- 

 lished ; though over a hundred plates of the 

 Gasteropoda were completed, and the text was 

 being printed, at the time of his death. 



The number of species described amount to 

 tiiirtv-six iiundred. When we reflect that e.ach
