a description of recent additions to the Queensland Museum, with 

 several plates showing the novel exhibits lately installed, for 

 example, that of the kangaroos and wallabies. There follow a 

 series of twenty-two original articles, in part ethnographic and 

 in part zoological. Under the latter head are to be noted a series 

 of papers by J. Douglas Ogilby and others on Australian fishes, 

 and also a number of supplements to an earlier memoir by 

 A. A. Girault on Australian Hymenoptera Chalcidoidea.

Obituary. 



Dr. Eugene Woldemar Hilgard, professor of agriculture in 

 the University of California from 1874 to 1904, died in Berkeley 

 on January 8 at the advanced age of eighty-three years. Born 

 in Zweibrilcken, Bavaria, in 1833, he came to this country at an 

 early age, but was later educated chiefly in Germany and Switzer- 

 land. He is best known for his investigation of soils, in which 

 he was a pioneer ; these were begun when he was State geologist 

 of Mississippi (1855 to 1873). His work on soils embraced both 

 the relation to their fertility and to plant adaptations, and in- 

 cluded observations made in the laboratory as well as in the field 

 and forest. He was the author of numerous Government and 

 State reports on agricultural subjects and his labors had practical 

 results of great value to the farming interests of the country. 

 His brother, Julius E. Hilgard (d. 1891), was long connected with 

 the U. S. Coast Survey and its Superintendent from 1881 to 1S86. 



Dr. Arthur Vaughan, of Oxford University, a distinguished 

 investigator in geophysics and in paleontology, died in December 

 last at the age of forty-seven years. He is best known to 

 American geologists for his detailed and valuable work in zoning 

 and correlating the Lower Carboniferous of Great Britain and 

 Belgium. 



Professor Francis Richard Barrell, who held the chair of 

 mathematics at the University of Bristol, died on December 2, at 

 the age of fifty-five years. 



Mr. Henry Eeles Dresser, the English ornithologist, died at 

 Cannes on November 28, at the age of seventy-seven years. 



Professor Charles Rene Zeiller, the French paleobotanist, 

 died in Paris early in December.
