When a number of such characters accumulate, we further honour them by assigning a new generic name.
The generic name of Trypanosoma was conferred by Gruby in 1843 upon the wellknown parasite of frogs.
Blyth long ago proposed the name Caprolagus for the remarkable spiny rabbit of the western Himalayas, while the generic name Oryctolagus was suggested later for the rabbit, and Sylvilagus for the American "cotton-tails"; but none of these was accorded general acceptation.
Externally the most striking feature of the bird is its head, armed with a powerful beak that it well knows how to use, and its face clothed with hairs and elongated feathers that sufficiently resemble the physiognomy of an owl to justify the generic name bestowed upon it.
The individual and collective influence of the several impurities which occur in the product of the Heroult cell is still to seek, and the importance of this inquiry will be seen when we consider that if cast iron, wrought iron and steel, the three totally distinct metals included in the generic name of "iron" - which are only distinguished one from another chemically by minute differences in the proportion of certain non-metallic ingredients - had only been in use for a comparatively few years, attempts might occasionally be made to forge cast iron, or to employ wrought iron in the manufacture of edge-tools.
