          Cambridge, Monday Morning 


 Dear Doctor


 I have yours of the 6th. I am 
 sorry that the Text Book, the sheets of 
 which go on to New York to-morrow, cannot 
 be really out till you or you are well advanced in 
 your course. But then is the Manual. 


 Agassiz says the missing [crossed out: plate]
 sheets of drawings were some of them moving
 spores of Algae, &c., which he used in 
 Charleston, & which have not yet returned. 


 I hope to hear you have a good class. 


 I have directed [Antoine] Sonrel to send on 
 to Endicott the stone that has Fremontia
 on it. What has become of the 
 proofs & the drawings? The stone is 
 to go back to Tappan & Bradford, Boston 
 after E. [Endicott] has worked off the edition, or 
 E. [Endicott] is to account for it with T. & B. [Tappan & Bradford] if he
 retains it. I have Sonrel's bill paid, 
 here among others I have to pay for Henry.
