<ol><li>A preface by the Royal Society of Siam, dated 9 January 2475 BE (1933 CE).</li>
<li><i>Prawat Sangkhep Chon Chat Maeo Yao Musoe</i> ("Abridged History of the <a href="https://en.wikipedia.org/wiki/Hmong_people" class="extiw" title="w:Hmong people">Maeo</a>, <a href="https://en.wikipedia.org/wiki/Yao_people" class="extiw" title="w:Yao people">Yao</a>, and <a href="https://en.wikipedia.org/wiki/Lahu_people" class="extiw" title="w:Lahu people">Musoe</a> People") — Phraya Kasikanbancha (possibly Lek Burawat), a land officer of (the now defunct) Phayap Prefecture, discovered the original copy of this work in the prefecture and forwarded to the Royal Society, saying that an unnamed clerk of the prefecture had ordered district chiefs and other officers in the prefecture to conduct an examination and write its result as this work, intending to have it printed for distribution at the Siamese Museum Exhibition at <a href="https://en.wikipedia.org/wiki/Lumphini_Park" class="extiw" title="w:Lumphini Park">Lumphini Park</a>, Bangkok, but the fair was abolished, causing the work to be left unpublished. The Royal Society  then had it published for the first time as this book.</li></ol>
