虽然在光学科学中，借助于波动假说已经解释了这么多，但是，当任何明显的现象出现时，如果出现了意想不到的特殊性，为了与理论进行比较，描述它们可能是重要的。在我看来，我即将提到的那些情况就是这样，在这些情况下，通过某种或其他的显著补偿，普通的太阳光似乎起到了均匀光的作用，并使其消色差;如果”我可以用这样一个表达，在一个非常高度的完美。威廉赫歇尔爵士，我相信，首先，他注意到了通过两个接触放置的棱镜可以看到的非常美丽的彩色带。因此，假设ABC、ADC是两个相等的直角玻璃棱镜接触。我们假设边AB、BC相等，棱镜的厚度等于AB，在这种情况下，两者的组合将形成一个立方体。让两个棱镜轻轻地压在一起，他们的fhce AC，这必须事先清除任何粘附的灰尘，
A LTHOUGH so much has been explained in optical science by the aid of the undulatory hypothesis, yet when any well-marked phcenomena occur which present unexpected peculiarities, it may be of'importance to describe them, tbr the sake of comparison with the theory. Such appears to me to be the case with those which I am about to mention, in which, by means of a remarkable compensation of some kind or other, common solar light appears to play tile part of homogeneous light, and to achromatize itselat; if" I may use such an expression, in a very high degree of perfection.Sir William Herschel was, I believe, tile first who took notice of the very beautiful coloured bands which are seen by looking through two prisms placed in contact. Thus, let ABC, ADC be two equal right-angled glass prisms in contact. We will suppose the sides AB, BC to be equal, and the thickness of the prisms to be equal to AB, in which case the combination of the two will form a cube. Let the two prisms be gently pressed together by their fhce AC, which must be previously well c] eaned fi'om any adhering dust, and
