LIBRARIAN'S REPORT. 



The Librarian reports as follows : — 



The increase in the Library of the Institute by donations during the 

 current year has been one hundred and ninety-three volumes, besides 

 pamphlets to the number of three hundred and eleven. A detailed list 

 of titles and donors, made by the assistant Secretajy, is now laid on the 

 table. 



It will be seen that the Institute is indebted to Mr. Lawrence Heyden, 

 its late Recording Secretary, for a large proportion of the volumes and 

 pamphlets presented, one hundred and eighty-six of the former, and two 

 hundred and sixty-three of the latter being gifts of his. 



Among Mr. Heyden's cpllectipn will be found several publications, of 

 especial value, as relating to the early history of Canada and other por- 

 tions of this Continent. Also a fine old copy of Lysons' Environs of 

 London, in five volumes quarto, date 1796, bound in calf; and an interest- 

 ing Lavater, in three volumes octavo, London, 1797. 



From the Hon. Mr. Broadhead, at Washington, was received a royal 

 octavo volume of 899 pages, on " The Geology of New Jersey," with an 

 Atlas of eight large plates : also the Report of J, Ross Browne, on the 

 *' Mineral Resources of the States and Territories west of the Rocky 

 Mountains." This is a royal octavo volume of 674 pages. Its date 

 is 1868. 



The Boston Natural History Society has sent a copy of Harris's 

 " Entomological Correspondence," a royal octavo volume of 375 pages, 

 with fine coloured plates.

 Societies of Great Britain, the Continent of Europe, and the United States, 

 and sent in exchange for the Canadian Journal, have been duly received 

 throughout the year.

NOTE RELATIVE TO METEOROLOGICAL REPORTS FOR Jan. 1869. 



In cpnsequence of the progressive change in the distribution of temperature 

 through the year, it was found necessary to compute a new table of normal tem- 

 peratures as standards of reference. The normals, as derived from the ten years 

 1859-1868, have been employed from January 1869 inclusive. In the reports for 

 January and February 1869, in the Canadian Journal, a breach of continuity oc- 

 curs in the difFerenees of the daily means from their normal standards, which 

 was occasioned by using the old instead of the New Table for January. 



The differences should be as follows :
