[5] Subsequent observations (1882) by Secchi, Young, and others have demonstrated velocities far exceeding this; quite sufficient to project the solid matter clearly beyond the sphere of solar attraction.
[6] My first memorandum on this subject is dated April 23, 1840, in a Register of Ideas, then commenced in very early student days.
[7] Any reader of “The Fuel of the Sun” will perceive that the vaporous envelope which I have described as “an effectual jacket for limiting the amount of radiation,” is a complete theoretical anticipation and explanation of the “solar crust” of Respighi and the “Trennungschicht” of Zöllner. We agree perfectly in our conclusions, though arriving at them by such very different paths, and so independently of each other.
[8] What did he smell? Was it an emanation from the soles of my feet? If so, how did this aura get through the soles of my boots, which were thick? It could scarcely have been the odor of the boot soles themselves that he followed, as he recognized me afterwards at some distance. This suggests an interesting experiment, that anybody owning one of these dogs may easily try. Make a similar track to mine, but when on the way, take off the boots you wore on starting and change them for some one else’s boots, or a new pair, and watch the result from the window.

[13] The burnt card, burnt bamboo, and other flimsy incandescent threads now (1882) in vogue, merely represent Starr’s preliminary failures prior to his adoption of the hard adamantine stick of retort-carbon, which I suppose will be duly re-invented, patented again, and form the basis of new Limited Companies, when the present have collapsed.
