In this work, the part of the Risale-i Yafındilik "veiling treatise" found in the registered handwritten manuscript called the Cagataiische Sammelhandschrift ""Chagatai collective manuscripts in the Berlin State Library " has been studied. Manuscript is in case of prose. Generally the topics of covering, clothing manufacturing, etc until the period extending starting from Hz. prophet Adam to Hz Muhammad (a.s.) have been discussed. When the language characteristics and the paper type are, the text can be said that it was written at the end of theXVIII. century. The study consists of four sections regarded as important namely language features, transcription, transmission to Turkey’s Turkish and facsimile. In the first section, the word group with the sound of and morphological characteristics that stand out in the text has been analysed, in the second   section, the transcript of the text has been made, in the third section, the text has been transferred to Turkey’s Turkish, in the fourth section its facsimile has been carried out.  When the writing features of the text are examined, it is seen that many Arabic and Persian words are written differently from the source language. These differences of writing that will not be able to be evaluated (considered) as a simple scribal (prospecting) mistake are also found in today's Uyghur Turkish writing. Arabic and Persian words can be thought that they have taken the present forms in this direction of the writing features by developing as from the XVIII. century.
