The sixth celebration of Founder's Day at 

 the Carnegie Institute, Pittsburgh, took place 

 on November 7. The principal speaker was 

 Ex-President Grover Cleveland. The occasion 

 was made memorable by the opening of the 

 Sixth International Exhibition of Contemporary 

 Paintings and by the display of a larger num- 

 ber of new exhibits in the Carnegie Museum. 

 Among the latter are the skeleton of Titano- 

 therium, and portions of the skeleton of 

 Diplodocus Carnegii, recently restored under 

 the care of Professor J. B. Hatcher, a fine 

 specimen of Rhinoceros simus Burchell, a col- 

 lection of petroglyphs from western Penn- 

 sylvania, and large additions to the collections 

 of mammals and birds, as well a long array of 

 exhibits in other departments of the Museum. 



Mr. C. W. Gilmore, who has been employed 

 during the past summer in continuing the ex- 

 cavation at Camp Carnegie, on Sheep Creek, 

 Wyoming, begun two years ago by the Car- 

 negie Museum, completed his work last week. 

 A carload of fossils, consisting principally of 

 the remains of a very large and perfect specimen 

 of Brontosaurus has been shipped to Pittsburgh 

 and will shortly be delivered at the Museum, 



The collection of land, marine and fresh- 



water shells, belonging to the estate of the late 

 W. D. Hartman, M.D., of West Chester, Pa., 

 has been purchased by the Carnegie Museum 

 in Pittsburgh. Over nine thousand species are 

 represented in the collection, v/hich contains 

 many types and cotypes. It is particularly 

 rich in North American species and in the 

 species found on the islands of the Southern 

 Pacific. The addition of the Hartman collec- 

 tion to the other conchological collections 

 which have in recent yeai-s been secured by 

 the Carnegie Museum gives this institution one 

 of the largest assemblages of conchylia in the 

 United States. 



In September the Wisconsin Natural History 

 Society sent two expeditions to the neighbor- 

 hood of the Fox River in Waukesha County 

 for the purpose of making surface surveys of 

 a number of still unrecorded mound groups 

 which are liable to be destroyed when the land 

 is put under cultivation as is to be done next 

 year. The first expedition surveyed and plot- 

 ted four groups and several isolated works in 

 the vicinity of Big Bend. One of them is in- 

 dicated on Dr. Laphan's map, but no descrip- 

 tion is given by him. The second expedition 

 was sent to the neighborhood of Mukwanago, 

 about four miles from the first party. It sur- 

 veyed a number of burial and oblong mounds. 

 Nearly all the burial mounds were found to 

 have been disturbed by farmers and others liv- 

 ing in the region. 



The Russian Imperial Geographical Society 

 has received news from the Kozloff expedi- 

 tion, sent out to explore the headwaters of

 lections have been obtained. 



A Copenhagen despatch says that Dr. Nan- 

 sen, the Arctic explorer, is arranging for bio- 

 logical research in northern waters; Norway,

 Government has resolved to invite the inter- 

 ested states to hold a conference at Copenhagen 

 to discuss the subject. 



The Twentieth Century Club of Boston has
