Was it, if capable of respiration, dense enough to sustain life like mine? I extracted the plug from the tubular aperture through which I had pumped in the extra quantity of air that the Astronaut contained; and substituted the sliding valve I had arranged for the purpose, with a small hole which, by adjustment to the tube, would give the means of regulating the air-passage at pleasure.
It is the proper air-passage; and because it has this important function to discharge, it is out of the way of violence or injury. The 'lachrymal duct' is the channel through which the superfluous tears are conveyed to the lower parts of the nostril. A long canal here commences, and runs down and along the maxillary bone.
The upper cavity, into which the nasal canals open, now develops into the nasal cavity, the air-passage and the organ of smell. When these do not, sometimes, completely join in the middle, a longitudinal cleft remains, through which we can penetrate from the mouth straight into the nasal cavity. This is the malformation known as "wolf's throat." "Hare-lip" is the lesser form of the same defect.
The peculiar depression between the nasal and frontal bones in this breed of dogs, while it almost totally obliterates the frontal sinuses, may narrow the air-passage at that spot, and cause greater irritation there from the unusual rush of the air, and especially if the membrane becomes inflamed or any foreign body insinuates itself.
They only threaten life when growing in the vicinity of vital organs, and then only in virtue of their situation for example, death may result from an innocent tumour in the air-passage causing suffocation, in the intestine causing obstruction of the bowels, or in the vertebral canal causing pressure on the spinal medulla.
A small well is formed in the centre of the platform, about eighteen inches in depth and diameter, egg-shaped. A few inches from the bottom of this well is an air-passage, connected with a pipe and bellows. The well is then filled with alternate layers of charcoal and pulverized iron ore; the fire is lighted, and the process of smelting commences.
The VENTAYLE, or "air-passage," is another name for this.

From its position the swelling is liable to press on the vagus, recurrent and sympathetic nerves, on the air-passage, and on the œsophagus, giving rise to symptoms referable to such pressure. There may be cerebral symptoms from interference with the blood supply of the brain.
Vaso-motor disturbances and contraction of the pupil on the right side may result from pressure on the sympathetic. Death may take place from rupture, or from pressure on the air-passage. [Illustration: FIG.
