    would follow. [A lighted match was brought to the mixture, which immediately exploded with a sudden flash, evolving a dense white smoke.] There you see the result of the action of chemical affinity, overcoming the attraction of cohesion of the particles. Again, here is a little sugar Q^), quite a different substance from the black sulphm-et of antimony, and you shall see what takes place when we put the two together. [The mixture was touched with sulphuric acid, when it took fire and burnt gradually and with a brighter flame than in the former instance.] Observe this chemical affinity travelling about the mass, and setting it on fire, and throwing it into such wonderful agitation! I must now come to a few circumstances which require careful consideration. We have already examined one of the effects of this chemical affinity — but to make the matter more clear we must point out some others. And here are two salts dissolved in water. ('^) They are both colourless solutions, and in these glasses you cannot see any difference between them. But if I mix them, I shall have chemical attraction take place. I will pour the two together into this glass, and you will at once
