Cap. _6._ _Of the causes of this disease._ The causes of this disease and of the _Symptoms_ belonging therunto, haue euer bin found hard to be described particularly: and especially in a vulgar tongue, I hold it not meete to discourse to freely of such matters, and therefore I doe craue pardon if I do but slenderly ouerpasse some poynts which might be otherwise more largely stood vpon The causes of this disease are either internall, or external. The internall causes may be any thing contained within the bodie, as spirit, blood, humors excrements, &c. whereby this part is apt to be offended, but principally they are referred vnto these two, [50]blood, and nature.
