 An examination of the paper proves conclusively that it is the latter, to

 Henry Lee, and marginal notes in the handwriting of Arthur Lee, both 

 of which are attested by Richard Henry Lee, the grandson of the former, 

 on the document itself. As Arthur Lee was absent from this country in

 the Academy for that purpose. 



The Committee approved of the proposition and requests the Society to 

 make an appropriation of $255 out of the income of the Michaux fund to 

 meet the expenses of the Lectures. 



In January, 1890, the Society made an appropriation of $200, out of the 

 income of the Michaux fund, to Prof. Heilprin, towards the expenses of 

 his expedition to Mexico and Yucatan, and your Committee has just 

 received from him a paper entitled "Observations on the Flora of Northern
