Ammal Report.] 10 [May 5. 



has reached the four hundredth page, and includes the records 

 of the last regular meeting, held a fortnight ago to-day. Early 

 in the year we published the Annual Report and our first 

 Annual, of one hundred and twenty-eight pages, with which 

 you are all familiar ; in the winter an outline Physical map 

 of North America, to be used in indicating the boundaries of 

 the geographical distribution of animals and plants ; a large 

 edition was printed, and copies are sold at cost to induce stu- 

 dents to engage in a study which promises the best results. 

 Recently we have issued two important works, the fourth and 

 concluding part of the first volume of our Memoirs, and the 

 first volume of our Occasional Papers ; the former included 

 papers by Col. Whittlesey, upon the weapons and military 

 character of the ancient mound builders of the West, and 

 upon the physical geology of Eastern Ohio ; by Mr. Vose on 

 the distortion of pebbles in conglomerates, mainly drawn from 

 his studies near Rangeley Lake in Maine ; by Mr. Allen upon 

 the birds which he observed in Iowa, Illinois and Indiana ; 

 by Mr. Brigham upon Hesperomannia, and upon the recent 

 eruption of the Hawaiian volcanoes ; by the late Mr. Mann 

 upon new genera of Hawaiian plants, with an analysis of the 

 Hawaiian flora ; and by Prof. Sumichrast upon the geograph- 

 ical distribution of the birds of Vera Cruz, in Mexico. 



Our new octavo series, called "Occasional Papers," is intro- 

 duced by a volume of the Entomological Correspondence of 

 the late Dr. T. W. Harris, edited by the Secretary ; the body 

 of the work is made up of both sides of the correspondence 

 between Dr. Harris and Prof. Hentz, Drs. Melsheimer, Le- 

 Conte, Zimmermann and LeBaron, Miss Morris, and Messrs. 

 Doubleday, Herrick, Say, Darling and Higginson. Numerous 

 notes, principally upon the earlier stages of Insects, are added 

 from Dr. Harris's mss., and some articles which originally ap- 

 peared in obscure and now inaccessible Journals, are repub- 

 lished. An interesting Memoir of the author is given by Col. 

 Higginson, and a steel portrait from a photograph furnished
