And furthermore, by my arrangement of the gaa passage with reference to each chamber and ita leading pipes, I effect such an extended circuit of gaa in contact with the vaporizing surfaces aa to enable me to bring the whole apparatus into a very email compass, in comparison with others in use, and having the same amount of naphthalizing power. I do not claim the apparatus made of metal or other suitable material merely, as such solid apparatus is merely the skeleton, to auatain the paaaagee or tubea made of cloth, which line auch solid chambera, accurately forming a tubular paaaage of cloth through which the gaa, air, or aaturated vapor ia driven. But I claim the arranging of tubular passages made of cloth, or other aimilar poroua fabric, which elevate by capillary action the fluid in the chamber, allowing space sufficient for the pasaage of the eeriform fluid, and allowing complete saturation of the latter, in the manner and for the purpoae apecified.
