Following the first special discussion on ‘‘ Natural Divi- 
sions in Geology of World-wide Extent,” Prof. H. S. Wil- 
liams pointed out the réle which the “cuboides zone” 
played in this respect, whilst Dr. Ami pointed out the 
world-wide extent of certain graptolitic zones and the rea- 
sons which probably led thereto. Dr. Le Conte considered 
at length the present Human Period. 
OBITUARY NOTICE. 
Dr. Joun Raz, F.RS., F.R.GS. 
In the death of Dr. John Rae, Canada and Natural Science 
have lost a warm friend, and the world loses one of the 
most active and energetic of geographical explorers. Dr. 
Rae was born at the Hall of Clestrain, Orkney Islands, on 
September 30th, 1813, and died at No. 4 Addison Gardens, 
London, on July 22nd, 1893, having nearly attained the 
age of 80 years. The following notice is from the Cana- 
dian Gazette : 
At the beginning of April last Dr. Rae was seized with a violent 
attack of influenza followed by congestion of the lungs, and although 
at times during the interval he seemed to be getting better, he never 
permanently recovered. Three weeks before his death his conditton 
seemed so greatly improved that arrangements were made for him 
to leave his bedroom for the first time since April, and Mrs. Rae had 
even gone so far as to contemplate his removal to’ the seaside. On 
July 13th, however, he had a sudden and severe relapse, though 
hopes were still entertained of his recovery when he passed away 
last Saturday. Up to the very last he was perfectly conscious, his 
robust physique seeming to defy even the ravages of time, and on 
the morning of his death he read through the whole account of the 
Bisley meeting, taking an especial interest in the doings of the 
Canadian team. The remains are to be conveyed to Kirkwall, Ork- 
ney, and will be interred in the cathedral burial ground by the side 
of those of his old friend and companion, Dr. Bakie, the African 
traveller. 
Dr. Rae was popularly known as the discoverer of Sir John Frank 
lin’s remains. He was born at the Hall of Clestrain, Orkney Islands, 
on September 30th, nearly eighty years ago. He studied medicine at 
the University of Edinburgh, and in 1833 was appointed surgeon to 
the Hudson’s Bay Company’s vessel which annually visited Moose 
Factory on Hudson’s Bay. In June, 1846, he set out on his first voy- 
age of exploration on behalf of the same company, and so success-
