摘要：

The density of white rhinoceros Ceratotherium simum simum and black rhinoceros Diceros bicornis minor horn was ascertained using the mass and volume of 43 anterior and posterior horns. The horn density was then used to derive a method of calculating the anterior horn mass accurately without having to weigh the horn. It is thus possible to calculate the anterior horn mass of a live rhinoceros. The relationship between some horn measurements and horn mass were also examined using curvilinear regression. The correlations describing the relationship between horn mass and anterior horn basal circumference for males and females separately were found to be the highest.
