To Dr. Weber, November 15, 1866 



You wrote Aug.31, and ? Nov. 18865, April 12 and October 10 1866; but the 

 letter from November 1865 did not arrive. I wrote September 14 and the 4 th and 

 3(f of May 1866. Both ofthe last letters must be lost and the one from May 30 

 was particularly important because it discussed the Cereen scientifically. I did not 

 keep any copy. 



Please observe and collect conifers when possible. Branches and seeds 

 of these; and when they produce in the summer , male and female flowers.
