I have taken the liberty of sending with them two copies of the catalogue of our library, one for yourself and one for the city council of Paris, and also a small packet addressed to yourself containing a number of letters of acknowledgement for the works you kindly forwarded to our association. With sentiments of the highest respect I remain, Your most obedient servant, H. K. BULL, Corresponding secretary. STATE OF RHODE-ISLAND. Brown University, Providence, January, 29th, 1846. DEAR SIR, ....Your letter to the Governor has been received, presented to the legislature and referred to the committee on education. The chairman of the committee, M. Goddard, formerly a professor in our college, presented a report with resolutions thanking you for your generous exertions, and particularly for your handsome presents, and voting several extra copies of all reports and documents published by the state and authorising the governor to pay all charges that may occur for the packing up and transportation of said books and any others to be sent to us from Paris, through your agency. This was carried through the House and the senate unanimously and it is I believe the only question which has been decided unanimously in our legislature for a long time.... You will probably receive the report and the votes, by this steamer or the next. The Rhode Island-Historical Society have also passed votes of thanks and resolutions in favor of your project which you will receive soon. As to the books I shall make up a box and forward it to you as soon as I can. I write in great haste at the last moment before closing of the mail thinking it better to write an unfinished account of the affairs than to keep you longer in suspense. I beg your to believe me with the greatest respect, Your obedient servant, C. C. JEWETT. MR. A. VATTEMARE.
