"Wallace, an Englishman, published a book that had the concept of evolution which inspired Charles Darwin. He wrote about the idea of natural selection and the survival of the fittest. Later on both Wallace and Darwin wrote on the theory of evolution in the book, “The Principle of Biology”."(Creation vs Evolution - Part 1, 2 July 2006. The sermon note available here)
There is no such publication. Charles Darwin and Alfred Russel Wallace co-authored only one article together in 1858 titled "On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection" which was published in the Journal of the Proceedings of the Linnean Society of London. Zoology 3: 46-50.

Rev. Dr. Stephen Tong needs to get his information right and stop tampering with facts. From an article, he bloated it into a 'book'; from a technical title, he changed it to a generic caption.
Besides, not sure whether did Rev. Dr. Stephen Tong meant that it was Alfred R. Wallace who coined the term "survival of the fittest" or the idea behind it. If it is the former, he is wrong. The term was coined by Herbert Spencer in his book 'The Principles of Biology' published 1864. If it is the latter, he was giving a ambiguous abstraction that does not really convey anything much about what Wallace was really writing about.
Perhaps, Rev. Dr. Stephen Tong is confused between the work of Herbert Spencer with those of Charles Darwin and Alfred R. Wallace. If that is the case, it is time for him to preach-teach with notes at hand so that he would stop giving out false information, or just stop talking about subjects that he is confused until he got his facts right.
