Burma to Rangoon. He proposes to start from Canton and 

 attempt the ascent of the Si-kiang or Canton river to the highest 

 navigable point, and thence pass through the southern part of the 

 Yunnan province and the Shan states by way of Kiang-hung, 

 Kiang-tung, Zimmay, and Shuaigyeen or Tonghoo, to Rangoon. 

 He expects to travel over one thousand miles of new ground, 

 and to bring back a full description of fifteen hundred miles of 

 country hitherto undescribed. The two great objects of Mr. 

 Colquhoun's adventurous journey are to collect information of 

 permanent value to geographical science, and to gather materials 

 for a journal of travel likely to prove interesting to the general 

 public- — The town of Tokio, Japan, by a recent census was found 



to contain 1,064,331 inhabitants. Dr. Crevaux, when last heard 



from, had reached the sources of the Rio Pilcomayo, S. lat. 21°, 

 W. long. 68° 20' 15", in the Republic of Bolivia. Some very im- 

 portant geographical observations had been made in connection 



by telegraph with the Cordova Observatory. The Nature states 



that a Russian naval officer has invented a very ingenious appa- 

 ratus for ascertaining the depth of the sea without the use of a 

 costly and heavy line. Indeed, no line at all is used. The in- 

 strument consists of a piece of lead, a small wheel with a con- 

 trivance for registering the number of revolutions, and a float. 

 While the apparatus sinks the wheel revolves, and the registered 

 revolutions indicate the depth. When the bottom is reached, the 

 lead becomes detached, the float begins to act, and the machine 

 shoots up to the surface, where it can easily be fished up by a net 



and the register read off. The celebrated Indian explorer, 



Nam Singh, or the Pundit No. 9, is dead. He was one of the 

 m ost r. urkabh travelers of this centurx , his explorations in the 



1 rans-Himalayian regions, and especially in Thibet in the ser- 

 vice of the Trigonometrical Survey of India, were most success- 

 ful and important. The Rev. W. S. Green has undertaken the 



exploration of the great glaciers of New Zealand, and the ascent 

 of some of the highest peaks of those islands, several of which 

 have never been attempted. He is accompanied by two vvell- 

 ^I'wvn Swiss guides. Afterwards Mr. Green proposes to visit 

 New Guinea and ascend Mount Owen Stanley. Captains Bur- 



°" and Cameron have been visiting gold deposits in Apollonia 

 and other districts near Axim, west coast of Africa. They were 



o start for the interior via the Ankobra river on February 25th 



ast. They are making a valuable collection of objects of natural 



History it i s thought that the American Mission will fix their 



Ration at Bailundo, fifty miles from Bine, in the center of the 



e gton , n W hich the Ganguela language is predominant, and on 

 tne line of the densest population ' towards the center of Africa.
