Each time there was a spark discharge from the induction coil, the experimenter found that a small electric spark also generated between the knobs of the wire loop, thus showing that electric waves were projected through the ether.
But in the case of the typical laboratory experiment, everything is ultimately based on self-observation; only we have to do with the self-observation under exact conditions which the experimenter is able to control and to vary at will.
It was the expectation of the experimenter that the pole would be used to push the banana through the box, but as a matter of fact the ape used it, first of all, to pull the food toward him, thus indicating a natural tendency which is important in connection with the statements just made. Subsequently he learned that the banana must be pushed through and obtained at the farther end of the box.
But when the experimenter in the midst of the apparatus of science, and surrounded by things which imposed on the vulgar, denied their value, and laughed at the legends of wealth and strength obtained by their means this fact of itself went very far towards convincing him that Basterga had made a discovery and was keeping it back.
The bias was the same, but it took a fairer form. The hens were both given a decent variety of food and some form of meat. The bulk of the grain was corn in the carbonaceous, and wheat in the nitrogenous ration. The results were in favor of the corn. This astonished the experimenter. He tried it again and again tests came out in favor of corn.
And because Galen was a skilful anatomist, and a skilful experimenter, he was able to show in what particulars Erasistratus had erred, and to build up a system of thought upon this subject which was not improved upon for fully 1,300 years. The same facts may be looked upon by different people from different points of view.
T'e bacilli of bread, t'e yeast, svarming vit millions of millions of little spores, go into t'e housevife's dough, and it is bad bread; but t'at is not t'e fault of t'e bacilli mein Gott, no! for vit' t'e bacilli t'e baker makes goot bread. T'e bacilli of butter, of cheese you haf studied t'em. T'e experimenter puts t'e germs of good butter into bad cream and it becomes goot. It ripens.

Several of the more important discoveries of the present generation, which cost many weary months of toil, have been enumerated in a score or two of lines, so that every experimenter could set up his apparatus and get the results in a few minutes.
Do not be so impatient to set the town right concerning the unfounded pretensions and the false reputation of certain men of standing. They are laboring harder to set the town right concerning themselves, and will certainly succeed. Suppress for a few days your criticism on the insufficiency of this or that teacher or experimenter, and he will have demonstrated his insufficiency to all men's eyes.
