THE YOUNG PROFESSOR 185 
Garrigue proposed to publish such a translation 
brought up to date and it is this which Marsh refers to 
in the above cited letter. In accepting the editorship, 
Baird undertook not only that function but the personal 
revision and translation of a great part of the text; 
supervising and editing the remainder which was entrusted 
to specialists for revision. 
The correspondence with men devoted to the various 
branches of exact science brought the editor into close 
relations with most of those then existing in the United 
States. He had, during his journeys and by correspond- 
ence, already become well known to nearly all the active 
zoologists of the day, and the work now undertaken, 
which lasted nearly four years, was incidentally a means 
of making him, after Agassiz, the most generally well 
known man of science in America. The work was pub- 
lished in 1852 under the title of ‘The Iconographic 
Encyclopedia,” and the contract with the publisher was 
signed March rs5th, 1849. After this was undertaken 
the entries in his Journal become much more concise, 
and often the word ‘Bilder’? alone occurs to indicate 
the general tenor of his occupation, which became regular 
almost to monotony; being practically taken up with the 
encyclopedia and his college work. 
He had meanwhile received the following letter from 
Professor Henry: 
From Joseph Henry to S. F. Baird.

My pear Si1rR,— 
Your communication of Sept. 28th has just reached me at Prince-
