the small shrew .( Tupaia); none of the numerous rodents 
but one or two squirrels, and even these do not extend as 
far as Timor. We thus have the Sunda chain divided 
distinctly and definitely into an Asiatic and an Australian 
portion, the dividing line coinciding with the deep-sea 
channel existing between Bali and Lombok. This 
boundary is now universally known as “Wallace’s line.” 
The chain is also somewhat sharply divided between 
the two great races of the archipelago, the Malays and 
Papuans, although the boundary occurs at a different 
point, the former people extending as far east as Sum- 
bawa, while from Flores through all the other islands 
the latter prevail. 
2. Bali. 
The two islands of Bali and Lombok are the only 
portion of the Malay Archipelago in which the old 
Hindu religion still regularly maintains itself, though 
Hindu Kajas also exercise rule in the Ke Islands. 
Bali is almost 90 statute miles in extreme length, 
and of irregular shape, with an area of about 2075 
square miles. It is separated from the eastern extremity 
of Java by a strait hardly more than a mile wide, and 
like that island, is mountainous throughout, excepting a 
small portion in the south, the main chain running from 
west to east in apparent continuation of that of Java. 
There are several active volcanoes, the most important of 
which, perhaps, is Batur (whose height has been estimated 
by different observers at 3940 and 6400 feet), which is 
in constant activity, and caused great destruction by an 
eruption in 1815. Batu Kau (9600 feet) is also active, 
but Abang (7500 feet) and Agung (10,500 feet)—the 
latter the highest peak in the island—are believed to be 
extinct, although Agung, or Bali Peak, as it is called by
