lantern wheel

This is allied to the cogwheel, the bars or spindles which connect the parallel heads being so spaced and proportioned as to engage with the cogs of the spur-wheel. It is a cheap form of wheel, and is seldom used where facilities are at hand for making better. It bears the relation of a pinion to the spur-wheel. It is sometimes called a wallower or trundle wheel, from the trundles or rundles of which it is made. boil, boy; pout, jowl; cat, çell, chorus, chin, bench; go, gem; thin, this; rates on evaporation in small white prisms. Heated to 190° it turns brown and gradually decomposes. Strong nitric acid di olves it, giving rise to an orange-red color. Sulphuric acid gives with it a faint violet color.
