Memo 1SZ-06-02

To the Physician, Mu Chenghan,

''We have heard reports of an outbreak of illness, caused by the interaction of seawater with the miasma of the surrounding marshlands, which has pervaded Tanzhou - and has for eight of the past 11 years. Your understanding of illness and of its causes, as outlined in your Treatise, has been at odds with established medical knowledge and procedure. ''

''As such, we are giving you a chance to prove yourself through work. You are to investigate this illness in Tanzhou, and we will give you up to 30 days to complete your studies and return to the Capital. Here you will discuss this disease with Physician Guoh, the pre-eminent expert in this occurrence, in our presence. ''

For this period, you are entitled to use this edict and compel officials to render aid and access to you, with our approval.
