place in which they are incarcerated owing to an obstruction in their natural passage.
Now it may be again asked, whether the relation of a disease, such as fever, etc. with the deranged bodily humours is constant and inseparable, or otherwise. All human beings would be in danger of perpetually falling ill in the event of the said connection relation; being constant and unseparable; but in case of their separate existence, it is but natural that their characterstic symptoms should separately manifest themselves instead of being simultaneously present with fever, etc. as they are found to be in reality. And accordingly the theory, that diseases (such as, fever, etc.) and the deranged bodily humours have a separate existence, and are not prima facie intimately co-related with one another falls to the ground. On the other hand, the assumption of their separate existence invalidates the incontestable conclusion, that diseases such as, fever, etc. are fathered by the deranged humours of the body.
Hence it may be safely asserted that no disease can occur without the direct mediation or intervention of the deranged bodily humours. Yet the connection (relation) which exists between the two is neither constant nor separable. As the physical phenomena of lightning, storm, thunder and rain can not happen independently of the sky (cloud); and yet they
