Alfred Russel Wallace 
The Malay Archipelago, Vol. -2 

"The Malay Archipelago" is a two-volume book written by British naturalist and explorer Alfred Russel Wallace. The second volume of the book recounts Wallace's travels through the Malay Archipelago (present-day Indonesia, Malaysia, and surrounding areas) between 1854 and 1862. In Volume 2, Wallace continues his exploration of the region, documenting his experiences in New Guinea, the Moluccas, and the Philippines. He describes the diverse flora and fauna he encountered, including rare and exotic species such as the bird-of-paradise and the giant Rafflesia flower. One of the key themes of the book is Wallace's observations on the biogeography of the region, which he saw as a laboratory for the study of evolution. Throughout the book, Wallace also reflects on the impact of colonialism and the exploitation of natural resources in the region and offers insights into the social and cultural practices of the indigenous peoples he encountered.
