But how is itproved that smoke is positively charged with electricity I The writerreferred to says it is so charged by combustion. How can thisbe, when smoke is only produced by fire in which combustion is in-complete? Let this question of smoke, however, end in smoke,for it is not material, only in so far as its upward or downward 98 CAUSES OF NERVOUS AND BLOOD DERANGEMENTS. movement is instanced to show the electrical condition of the atmos-phere. I believe it is not questioned that the air is more dense indry than in wet weather, and it only remains for me to show thatthe atmosphere is more electrical on a wet day than it is on a dry one.To do this, it simply seems necessary to point to the effects observedupon telegraphic wires. It is only on cloudy, wet, or rainy days thattelegraphic operators suffer much inconvenience from atmospheric Fig. 32.
