It is expected that the Lectures will be delivered in the Hall of the 

 Academy of Natural Sciences, which has been kindly tendered to him by 

 the Academy for that purpose. 



The Committee approved of the proposition and requests the Society to 

 make an appropriation of $25o 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, lleilpiin, towards the expenses of 

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