    plied to their surfaces. He also constructed a battery of pieces of charcoal and different fluids. The first glass contained water, the second ni- trous acid; these are connected by wet cloths. He then connected the second containing the acid, with the third containing water, by means of charcoal, and so on for twenty or thirty pairs of glasses, the communication being formed from the water in the first glass to the acid in the last, a slight shock is perceived. M. La Grave, member of the Galvanic Society at Paris, formed a pile of brain muscle and layers of hat; he made many experiments before he succeeded: he formed first a layer of muscle, then a layer of brain, then a layer of hat, moistened with salt and water, this he tied to the insulated rods at the sides of the pile ; when he had formed sixty pairs of muscle and brain, he says its effect was decisive. Mr. Cruikshank constructed a trough of baked wood, containing pairs of metallic plates, the interstices formed by the pairs of plates he filled with the usual solutions. You will find these troughs much more convenient for your experiments than the pile. (See pi. III. %• 7.) Mr. Carlisle discovered that the Galvanic shock decomposed water. Mr.
