PISCES=SMELT»..GRAYLING. 731 
Inuazits the northern seas, and is never found so far south as the Mediter- 
ranean. Its name is supposed to be a contraction of “‘smell it,” from its 
very agreeable smell. The Germans, however, call it the stink-fish. Its 
form is very elegant; it is of a silvery color, tinged with yellow; and the 
skin is almost transparent. The largest we have heard of was thirteen 
inches long, and weighed half a pound.

Is in general of a fine silvery gray, but when just taken it is varied slightly 
with blue and gold. The scales are large; the first dorsal fin consists of 
twenty-one rays; this fin is spotted; all the rest are plain; the tail is much 
forked. It haunts clear and rapid streams, particularly those of mountain- 
ous countries. In Lapland, where it is very common, the inhabitants use 
its entrails, instead of rennet, to make their cheese from the milk of the 
rein-deer. The stomach is so hard and thick, that to the touch it appears like | 
eartilage. The largest that has been heard of was taken near Ludlow; it 
was half a yard long, and weighed four pounds six ounces. The ancients 
delieved that the oil from them would obliterate freckles and small pox 
marks.
