As knowledge gives us more understanding of conditions and diseases, it is valuable to look at the record and papers which are the foundation of this work of medical historical scholarship. Today, we believe we understand everything, but that supposition is simply not true. This work, based on a careful study of medical records and case notes of some distinguished medical practitioners of the day, discovered in the archives in Edinburgh, reveals how the practitioners of the period coped and attempted to manage what were the nervous diseases of the day. There is an aphorism that "to be ignorant of what occurred before you were born is to remain always as a child". Heather Beatty has ensured that the Consultant Neurologists of today do not need to be ignorant of what happened before they were born. This is a considerable addition to the historical scholarship for those who wish to avoid ignorance. She is to be congratulated on her work, which has been both diligent and imaginative.
