2 Dec. 1911, 
Bear Collins:- 
The following is all that I can pet on track of i n 
connection with the Wilkes expedition. 
The Brown University copy is a single volume containing 
numbered pages 116 to 514, with the probability that three preced¬ 
ing unnumbered rages should be 113, 114, and 115, me volume is 
a quarto (10 x 13 inches), apparently in the original cover- 
board sides covered with paper and a kind of red cloth or leatherette 
back. As far as page 203 (and also including the blank unnum¬ 
bered page 204) are cryptogams and the rest phanerogams. 
The plates are folded and bound with the text (in the oac oi the 
volume). Algae plates are numbered I to IX.; lichens, I and XI; 
Fungi, one unnumbered plate; Botany (i.e. 'barer ogams i .I oo £711. 
I can find no record of any 4to edition of the Musci, nor 
can I find any separated of the algae or cryptogams. 
My own copy of the tlusci is a foxdo (22 x 15 inches ), 
pages 1 to 32, plates 1 to 26, apparently not In the original 
cover (though it rnay be) and obtained in Feb. , 1911, from the 
sale of Win. Mitten's library by his daughter. 
These two volumes are the only ones I know anything about. 
The state library is at the State House, Providence, *-• * *
