We must have the fight during the four seasons of the year. In the cold seasons we will find lung and other diseases--croup, pneumonia, diphtheria, sore throat. All these do their mischief through the nerves of the neck. Where is or who is the great thinker who knows and can tell all of the duties and actions of the nerves of the neck, or what nerve failed and slept while a tubercle was formed in the lungs? Which nerve slept while fat is heaped up in useless piles in the body? Let us wake up! Consumption does not come without a cause. What plexus is overcome and allows the lungs to waste away? To what ganglion of the spine would the finger of reason point, and say, "that is the cause of _phthisis pulmonalis_?" In our search we find a division of nerves run from the brain through the regions of the neck, and find a point at which a branch leaves a greater nerve on a line that leads to the lungs. We will likely find a ganglion at which place all or much of one or both lungs are supplied. Then we, by reason, would see that freedom of action cannot be. If some substance should intrude by pressure on any nerve in that region, we must judge by conditions if that pressure has cut off nutrition equal to feeble condition of the lungs. DYSPEPSIA OR IMPERFECT DIGESTION. In our physiologies we read much about digestion. We will start in where they stop. They bring us to the lungs with chyle fresh as made and placed in thoracic duct, previous to flowing into the heart to be transferred to lungs to be purified, charged with oxygen and otherwise qualified, and sent off for duty, through the arteries great and small, to the various parts of the system. But there is nothing said of the time when all blood is gas (if ever) before it is taken up by the secretions, after refinement, and driven to the lungs to be mixed with the old blood from the venous system. A few questions about the blood seem to hang around my mental crib for food. Reason says we cannot use blood before it has all passed through the gaseous stage of refinement, which reduces all material to the lowest forms of atoms, before constructing any material body. I think it safe to assume that all muscles and bones of our body have been in the gas state while in the process of preparing substances for blood. A world of questions arise at this point.
