478 JOURNAL OF EXECUTIVE COMMITTEE. 



setts, which will have a great tendency to advance astronomical science in this coun ■ 

 try. It has been proposed that the Institution shall subscribe for a number of copies, 

 sufficient to supply the foreign observatories and distribute these in connection with 

 its other means of diffusing knowledge. 



Subscription to Association Report. — The American Association for the Advance- 

 ment of Science is now publishing, in a volume, the report of its proceedings. The 

 subscription to this volume is not sufficient to defray the expenses of it, and it has 

 been proposed that the Institution purchase one hundred copies, at $1 each, for dis- 

 tribution, as an important means of diffusing knowledge. The Association has pre- 

 sented to the Institution all the books which it receives in the way of donations, and 

 will, in all cases, co-operate with the Smithsonian Institution. 



A list of occultations, similar to that for 1848-9, has been prepared by Mr. Downes 

 for 1850, is now in the process of being 'stereotyped, and will probably be published 

 in the course of a few days. The cost of the calculation of these tables will be paid 

 by Lieutenant Davis, out of the appropriation made at the last session of Congress, 

 for the Nautical Almanac. The only expense, therefore, to the Institution for this 

 publication, will be the cost of the printing and paper. It has been printed, and 

 will be distributed in the early part of next week. 



Apparatus. — Dr. Hare's apparatus, in part, has been cleaned and displayed as far 

 as our room will permit. 



Several small invoices of apparatus have been purchased, consisting of such arti- 

 cles as will be required for the lectures of the coming winter. They are designated 

 in the bills. 



Dr. Hare has signified his intention of presenting a number of articles of appa- 

 ratus, not included in his first gift, to the Institution ; also, a collection of rare min- 

 erals, chiefly metallic ores. 



The Secretary has received a letter from the eldest son of Dr. Hare, expressing the 

 approbation of his father's family of the donation of the apparatus to the Institu- 

 tion, and their gratification with the manner in which the gift had been received. 



The Secretary has also purchased a set of plants, collected by the late Dr. Oakes in 

 the New England States, for which the sum of $20 has been paid. 



Lectures. — The Secretary has written to a number of gentlemen, distinguished in 

 literature and science, to deliver courses of lectures, before the Institution, during 

 the coming winter. Almost all, who have been addressed, have accepted the invita- 

 tion, and have apparently considered the invitation a compliment to their reputation 

 and standing. Their names are as follows :

Association of Teachers. — An Association of Teachers has been formed in this Dis- 

 trict, which has held its meetings in one of the rooms of the Smithsonian building.

 D. Gale, and Dr. Foreman. These meetings will be continued in the rooms of the 

 Institution, if the Executive Committee have no objections.
