| Description Of Item | This is an artificial series although some of the volumes within it do relate to each other. These volumes appear to be notes in preparation for lectures. A number of the volumes duplicate each other (and this is indicated in the entries) although not all duplications of content have been noted as this would require page by page comparisons. The volumes were probably written in different years, hence their similar content, but there is little information by which to date the volumes. The handwriting is inconsistent but it appears from some of the content that parts may have been copied. Some handwriting is clearly not Simpson's but in many cases those volumes duplicate some that have been signed by him. |
