本文叙述了日食对不同太阳机构电离的大气层的影响，并考虑了电离层中日食变化的实际观测。得出的结论是，E区和F1区的正常电离机构的速度与光的速度非常一致;因此，很自然地将这种机构与紫外光联系起来（尽管这里考虑的这种观察不能排除这种机构的可能性，对于这些层中的一个或多个层，由非常高速的微粒组成）。同样，有相当明确的证据表明，紫外线至少贡献了正常区域F2电离的一部分，并建议小体也可能有贡献。在未来的日食中，我们非常希望注意力集中在F2区域。
The effect of a solar eclipse upon air layers ionized by different solar agencies is described, and the observations of the actual eclipse changes in ionized layers are considered. The conclusion is reached that the normal ionizing agency for regions E and F1, has a speed closely agreeing with that of light; hence it is natural to identify this agency with ultra-violet light (though observations of the kind here considered cannot rule out the possibility that the agency, for one or more of these layers, consists of very high speed corpuscles). Similarly there is fairly definite evidence that ultra-violet light contributes at least a part of the normal region F2ionization, and a suggestion that corpuscles may also contribute. In future eclipses it is very desirable that attention should be specially concentrated on this region F2.
