Most of the notebook's pages are empty. This notebook contains the published article, 'On the Dialects of Scottish Gaelic', written by Donald Mackinnon for the Highland Society of Inverness (1890-1899?). Each page of the published article has been removed from its original source and pasted onto pages of this notebook. Alongside the inserted pages of the article, there are notes and annotations, presumably by Mackinnon himself. In the rest of the notebook, where there are no inserted pages from the article, are notes and discussions on various linguistic issues, including phonology and idiomatic expressions. The notes are distributed throughout the notebook, therefore there can be a number of empty pages between each handwritten note.
