Excerpt from Van Nostrand's Eclectic Engineering Magazine, Vol. 2: January-June, 1870 If the line of collimation gets disturbed in the field, and there are no facilities for rectifying it on the spot, set two hubs with the instrument, and place another one, by measurement, exactly between, for the true point. Even when the adjust ment is as perfect as it can be made, it is best, in setting hubs at long distances, to verify by rotating the plate; and, in gen eral, it is a good plan in ranging a tan gent, to alternate the side of the transit turned forward.

Excerpt from Van Nostrand's Eclectic Engineering Magazine, Vol. 20: January-June, 1879 Any process Of illumination which re turns to the confined atmosphere we. Breathe the products of combu'étion is theoretically Open to Objection. All methods of illumination up to the pres ent time have depended on some process of rapid combustion, oxygen being with drawn from the air, an equal bulk of car bonie acid returned to it, and oftentimes a large amount Of heat as compared with the amount of light liberated in the pro cess. If now we can illuminate without the subtraction Of vital and the addition Of mephitic air, and if, however, we can produce an intense light without a corresponding heating Of the surround ing atmosphere, we have made two steps of great hygienic value so far as the il lumination and ventilation of rooms is concerned.
