president's address. 
Of the Ordinary Members, two — Dr. Paul Howard MacGillivray 
and Mr. J. Bracebridge Wilson — were resident in Victoria. They 
have strong claims to be held in grateful remembrance by 
Australian naturalists Dr. MacGillivray belonged to a family of 
naturalists. His father was Professor of Natural History at 
King's College, Aberdeen, and his brother, the late John 
MacGillivray, was author of the " Voyage of the Rattlesnake." 
Since 1857 Dr. MacGillivray had followed the practice of his 
profession in Victoria, at the same time showing himself a public- 
spirited citizen much interested in the spread of knowledge and 
culture. Much of his leisure for many years was devoted to the 
study of Australian Polyzoa, and he was the author of an 
important series of papers thereon, contributed to the Proceedings 
and Transactions of the Royal Society of Victoria, or to Professor 
McCoy's Decades. These date from the year 1859. His important 
" Monograph on the Tertiary Polyzoa of Victoria " was passing 
through the press at the time of his death, and has since been 
published.

Science, out of pure love for it. In utilising his yacht in dredging 
and trawling he found his hobby. This was done in a scientific 
systematic way, with the object of accumulating stores of well- 
preserved material for the elucidation of the marine fauna of 
Port Phillip by specialists, he himself sharing in this part of the 
work as far as opportunity served. 
Nearer home we have lost, at the early age of 30, one of 
the younger school of naturalists — Arthur Sidney Olliff, who 
died December 29th last. Mr. Olliff came to New South 
Wales in February, 1885, to take up the work of Assistant 
Zoologist, in the Division of Entomology, at the Australian 
Museum, where he remained until his appointment as Entomologist 
to the Department of Agriculture, Sydney in 1890. He had 
been for some time in enfeebled health, and shortly before his
