1. The question whether the rabbit's spectral sensitivity curve is based on one spectral system or based on more systems is investigated. 2. For this purpose two different methods have been applied. The first method is a photometric match technique that made use of moving contrasts.

A survey is given of the standards used in photometry and spectroradiometry. After an introduction in Sec. I, the candela and lumen standards are discussed in Sec. II. Some problems related to heterochromatic photometry and the changes in the IPTS are mentioned in Secs. II.B and II.C, respectively. Section III deals with standards for spectroradiometry-
