The patient does not seem to trouble greatly about her wound: she clambers gallantly up the sides of the bell-jar under which I have placed her; she goes on hopping as before. Better still, she sets about browsing the vine-leaf which I have given her for her consolation. A few hours pass and the whole thing is forgotten. She has made a rapid and complete recovery.
It consists of an iron bell-jar inverted in the water, and moored at a depth below the agitation of the waves. In the upper part of the jar, where the pressure of the air keeps back the water, there is a delicate needle contact in circuit with a battery and an electric bell or lamp, as the case may be, on the shore.
With a sheet of glass passed across the web, I gather a series of lime- threads which remain fixed in parallel lines. I cover this sheet with a bell-jar standing in a depth of water. Soon, in this atmosphere saturated with humidity, the threads become enveloped in a watery sheath, which gradually increases and begins to flow.
I have here a glass bell-jar, with a cork fixed tightly in the neck, and I place the jar over a pan of water, while on the water floats a plate with a small piece of phosphorus upon it. You will see that by putting the bell-jar over the water, I have shut in a certain quantity of air, and my object now is to use up the oxygen out of this air and leave only nitrogen behind.
I take the field with an equipment which I am carrying across the country for the first time: a glass bell-jar, a wire-gauze cover and the various implements needed for handling and transferring my irascible and dangerous subjects. My search for burrows among the pebbles and the tufts of thyme and lavender is soon successful. Here is a splendid one.
So saying, he put the model under a large bell-jar, from which he exhausted the air with a pump; and even then it moved about with as much alacrity and freedom as it had done in the atmosphere. I confess that I was still haunted by a lingering suspicion of the machine and its inventor; but this experiment went far to destroy it.
If I had put a mouse under the bell-jar, instead of the phosphorus, the water would have risen just the same, because the mouse would have breathed in the oxygen and used it up in its body, joining it to carbon and making a bad gas, carbonic acid, which would also melt in the water, and when all the oxygen was used, the mouse would have died.
I flood them with caterpillar's blood obtained by simple pricks; I place the preparation under a glass bell-jar, in a moist atmosphere, to prevent evaporation; I repeat the nourishing bath by means of fresh bleedings and give them the stimulant which they would have gained from the living caterpillar.
