LETTER OF GIFT. 



PORTLAND, Aug. 22, 1873. 



MRS. ELIZABETH THOMPSON of New York City, to-day elected a member, 

 sympathizing with the purposes of our Association in the advancement of science, 

 and seeing the new crop of young and industrious scientific investigators who 

 are to form the future basis of this Association following in the footsteps of the 

 veterans of science who founded it, and being aware of the financial difficulties 

 which often beset the path of those noble men of science who labor more for 

 truth than for profit's sake, wishes to place at the disposal of the Permanent 

 Secretary the sum of one thousand dollars, to be used according to the directions 

 of the Standing Committee, for the promotion and publication of such original 

 investigations by members of the Association as may be accepted by the said 

 Standing Committee, to be published by means of this special donation. 



[Signed] P. H. VAN DER WEYUE. 



To the Standing Committee of the American 



Association for the Advancement of Science.
