I observed at Chibanda's a few green mushrooms, which, on being peeled, showed a pink, fleshy inside; they are called "chisimba;" and only one or two are put into the mortar, in which the women pound the other kinds, to give relish, it was said, to the mass: I could not ascertain what properties chisimba had when taken alone; but mushroom diet, in our experience, is good only for producing dreams of the roast beef of bygone days.
He could have these things added to his box of bricks by degrees, he would build with them and combine them and play with them over and over again, and absorb an intimate knowledge of their properties, just at the age when such knowledge is almost instinctively sought and is most pleasant and easy in its acquisition. These things need not be specially forced upon him.
It might further be shown, that in every instance a "cause," properly so called, is a substance or being possessing certain properties or powers, properties which may be called, if you will, the "laws" of that substance, but which necessarily include the idea of causation or efficiency; that in the case of mere physical agency, there must be a plurality of substances so related as that the one shall act on the other in certain conditions which are indispensable to their mutual action; and that these requirements leave ample room for those manifold adjustments and adaptations on which the argument from "design," in favor of the Perfections and Providence of God, is founded.
Whatever be the means of preserving and transmitting properties, the primitive types have remained permanent and unchanged, in the long succession of ages, amid all the appearance and disappearance of kinds, the fading away of one species and the coming in of another, from the earliest geological periods to the present day.
In this condition it absorbs eight hundred times its volume of oxygen gas, and this oxygen must be contained within it in a state of condensation very like that of fluid water. When gases are thus condensed, i.e. their particles made to approximate in this extraordinary manner, their properties can be palpably shown.
We are then, at this stage of our experiments, in the presence of a critical point, at which we do not know whether the matter is liquid or gaseous; for, in either condition, it has the same density, the same heat of constitution, and the same properties. It is a new state, the gaso-liquid state. An experiment of Cagniard-Latour re-enforced this explanation of the phenomena.
All the land along the railroad, instead of being raw desert, became suddenly warehouse sites; the vacant lots along the main street were snatched up for potential stores and saloons, and all the drab flats where the Mexican burros wandered became transformed to choice residence properties.
"To Hamar, Curtis and Kelson to the three of you in common is given the knowledge of inflicting all manner of torments and diseases, of imparting all kinds of injurious properties, and of causing plagues.
It is not enough that the intellect should see the evils and their remedy. We shall still postpone our existence, nor take the ground to which we are entitled, whilst it is only a thought and not a spirit that incites us. We have not yet served up to it. These are properties of life, and another trait is the notice of incessant growth. Men should be intelligent and earnest.
It has not yet given me the key, but it is something to know on what insecure, weak, and limited experiments our vaunted knowledge of the existence of the world of energy, of matter and their properties, depend." Frau Ellrich looked at him approvingly. "You speak beautifully, Herr Eynhardt, and it must be a great enjoyment to hear you lecture."
