ture of the family and of society; 2°, customary, 

 or in harmony with the habits and sentiments of 

 every-day life and law; 3°, impartial, affording to 

 both sexes equal opportunities for culture; 4°, eco- 

 nomical, using school-funds to the best advantage; 

 5°, convenient both to superintendent and teachers 

 in assigning, grading, instruction, and discipline; 

 and, 6°, beneficial to the minds, morals, habits, and 

 development of the pupils. The pamphlet concludes 

 by observing that "both the general instruction of 

 girls, and the common employment of women as 

 public-school teachers, depend, to a very great degree, 

 on the prevalence of co-education, and that a general 

 discontinuance of it would entail either much in- 

 creased expense for additional buildings and teachers, 

 or a withdrawal of educational privileges from the 

 future women and mothers of the nation." 



— Mr. Charles B. Dyer, a well-known collector of 

 Cincinnati fossils, died at his home on Wednesday, 

 July 11, after a painful illness of over three months' 

 duration. He was for many years engaged in amass- 

 ing one of the finest collections of local paleon- 

 tology in the country, which now reposes in the 

 Agassiz museum in Cambridge. His rarest fossils 

 were collected by himself, and his industry in the 

 pursuit of new and fine specimens was untiring. In 

 connection with Mr. S. A. Miller, Mr. Dyer issued a 

 few years ago, at his own expense, a pamphlet with 

 two plates, containing descriptions of new forms 

 from his collection, entitled ' Contributions to paleon- 

 tology.' Thirty years ago Mr. Dyer retired from 

 business with a moderate fortune, and devoted all his 

 time to collecting. He was an eccentric man, with 

 strong feelings, but a fast friend and a pleasant com- 

 panion. He was in the seventy-eighth year of his 

 age, and had lived in Cincinnati for over fifty-five 

 years. His name is attached to one of the common- 

 est crinoids of the Cincinnati rocks, Glyptocrinus 

 Dyeri, and to several very rare and beautiful forms 

 discovered by him. 



— The Imperial geographical society of St. Peters- 

 burg has awarded its great gold medal to H. W. 

 Abich for his researches into the geology of the Cau- 

 casus. The Liitke medal was received by W. K. 

 Dollen of the Pulkova observatory for improvements 

 in astronomical instruments; Vitkoiiski, Barsoff, and 

 Krasnoperoff have received medals for ethnographic 

 and statistical works ; Oshanin, for travels in Turkes- 

 tan, etc. Silver medals were awarded to Brunoii for 

 meteorological researches, and to Lessar, Sohultz, 

 Grladisheff, Kiseleff, Eodionoff, and Slovtsoff for sur- 

 veys and journeys, chiefly on the Asiatic frontier of 

 Russia. 



— The observatory at Moscow was among the 

 establishments of the northern hemisphere which co- 

 operated with Mr. David Gill, Her majesty's astrono- 

 mer at Cape Town, in securing observations of the 

 small planet Victoria, at its late opposition, for a new 

 determination of the solar parallax. The ninth vol- 

 ume (livraison i.) o/ the Annales of this institution 

 contains the results of these observations, together 

 with several papers by its director. Dr. Bredichin, 

 relating to comets and allied subjects.
