The College of Physicians have made available the transcriptions of reports submitted by doctors at the outbreak of WWI. All doctors were required to register with the Scottish Medical Service Emergency Committee. Those registration records have been transcribed and the transcriptions can be viewed at: http://smsec.rcpe.ac.uk/
The information provided:
Name of practitioner
Address of practitioner
Rank in Army if applicable
Sometimes there will be a reason why the physician was unfit to practice in the army and other times there will be a listing of his qualifications.
