The Peabody Academy of Science at Salem, Massachusetts, will open the second session of its summer school of biology July 6, the course to continue for six weeks. Four days in each week will be given to lectures and laboratory work, and one day to a dredging expedition. Entomology, together with spiders, crustacea, and vertebrate anatomy, will be the especial subjects of study this year, and as usual the advantages enjoyed by this institution for studying marine zoology will be fully utilized. Dr. A. S. Packard, assisted by Messrs. Emerton and Kingsley, will have charge of zoology, Mr. Robinson of botany, Rev. Mr. Bolles of microscopy, and Mr. Cooke of the dredging parties. Fees, $15, or for lectures only, $5. Board $5 to $7 weekly. Application should be made to Dr. Packard. A four weeks' school will be opened at the State normal school, West Chester, Pennsylvania, beginning July 11. Zoology and botany will be taught by Prof. M. W. Harrington, geology and physiological chemistry by Mr. V. C. Vaughan, and mineralogy by George G. Groff, all these gentlemen being connected with the University of Michigan. Elocution and industrial drawing will also be taught. Fees are for board and tuition $30, and tuition alone $12. Apply to Mr. George L. Maris, principal. Scientific excursions seem to be the order of the day. Mr. Woodruff of Detroit has planned one to make the tour of the world; and Mr. J. B. Steere of Michigan university, who spent several years in a journey of scientific character, says: "The expedition will probably leave New York in October or November next, going directly to the mouth of the Amazon, where some time will be spent in making collections in natural history. The island of Marajo will be the principal field for this work. Rio Janeiro will probably be called in at, on the way to the Straits of Magellan, which will be reached in January or February (the summer season there), and a stay will be made for the purpose of collecting. The expedition will then make its way northwest, cruising among several of the rarely visited groups of islands in the central Pacific, where there is every opportunity for making large and valuable collections of sea shells and corals as well as of the myriads of other and rarer things brought up by the dredge. Some stay will probably be made in New Guinea; but the next great object of interest will be the island of Borneo. It is supposed that the northeast and central part of this great island, which are the parts still unknown, can be best reached through the assistance of the Dutch traders at Macassar on the island of Celebes, where the expedition will touch on its way. It seems probable that entering from the east side, with the proper guides and interpreters, the interior of the island can be reached and explored, and perhaps a party may be able to reach the west coast. Borneo is less known than Central Africa, and there is a grand opportunity here for
