248 General Notes. [ April, 
R. N., and by Lieutenant Murphy, R. A., Cameron made a final start 
from the east coast for the interior on the 18th of March, 1873. 
The young lieutenant showed his admirable fitness for the work from 
the first. There were special and peculiar obstacles which entailed very 
heavy expenditure, and Dr. Kirk was of opinion that no expedition, 
starting from Zanzibar, ever had so many difficulties to encounter. 
Cameron gallantly faced and overcame them, and, in spite of them all, 
he reached Unyanyembe on the 4th of August, 1873. 
At this place all the members of the expedition suffered terribly from 
illness. Out of forty-five days Cameron himself was down with fever 
during twenty-nine, and was afterwards prostrated by a still more serious 
fever, of a remittent type, and inflammation of the eyes. It was here 
that the faithful servants of Livingstone, bringing with them the remains 
of the great traveler, and his journals and other effects, joined the relief 
expedition and received that aid which enabled them to reach the coast. ` 
Lieutenant Cameron sent down the Livingstone caravan to the coast, in 
charge of Lieutenant Murphy, with ample supplies for the journey; and 
the continued illness of Dr. Dillon obliged him also to return. The 
party left Unyanyembe on the 9th of November, 1873, and on the 17th, 
Cameron’s friend, Dillon, “a skillful and zealous officer, and a highly ac- 
complished scholar and firm and steadfast friend,” succumbed to the 
effects of overwork and a pestiferous climate. 
Cameron was now alone; but his work was not yet done. Living- 
stone’s servants had reported that a most important map belonging to 
the doctor had been left at Ujiji, without which the record of the great 
traveler’s discoveries would be very incomplete. It seemed to the 
young explorer that its recovery was a sacred duty, and he also consid- 
ered himself bound to do his utmost, with the means at his disposal, to 
further the cause of geographical discovery. With these objects, but 
still suffering acutely from the effects of fever and ophthalmia, Cameron 
set out from Unyanyembe for the west on the 11th of November, 1873. 
He kept on steadily working “ westward ho!” with dauntless persever- 
ance, until he reached the shores of the Atlantic. 
Traveling through a difficult and entirely new country, he discovered 
several of the southern tributaries of the Malagarazi and the interesting 
region they water, and on the 21st of February, 1874, he reached the 
shores of Lake Tanganyika. 
Cameron’s first great geographical exploit after reaching Ujiji was the 
survey of Lake Tanganyika, which he ascertained to be 2754 feet above 
the level of the sea. He launched his boats in March, 1874, closely ex- 
amined and surveyed the whole southern half of the lake, discovered 
the great stream called Lukuga, flowing out of it, and returned to Ujiji 
on the 9th of May. His invaluable map of the lake will be found facing 
page 72 of the Geographical Magazine for March, 1875, and was also 
published in the Proceedings of the Royal Geographical Society. Cam-
