BALEEN OR WHALEBONE.—This is that substance which 
gives the name to the so-called ‘‘Whalebone’’ Whales, as | 
distinguished from the ‘‘Toothed’’ Whales. The Whale- 
bone Whales do not possess teeth (except, in eonttaata cases, 
in their foetal condition). 
WHALE-MEAT MraAu.—This is a dried meal, made ex- 
from certain portions (like the tail end in the Fin-back 
- Whale), which are very free from oil. This is a highly 
nutritious foodstuff, containing (according to Salvesen) 
about 79 per cent. of protein. 
' WHALE GuAno.—This product is generally made from 
the flesh of the carease, with the addition of about -one- 
. third of the bony matter. It is said that an analysis of 
this shows nitrogen equivalent to about 8.50 per cent. of 
ammonia, and phosphoric acid equivalent to about 21 per 
cent. of tri-basic phosphate of lime. A guano is also made — 
from the refuse of the whole carcase, including all the bony — 
matter. This makes a valuable fertiliser, said to contain, — 
the equivalent of from about 10 to 11. "15 per cent. of 
ammonia and 17 to 23 per cent. of phosphate of lime. 
Bone Mrau.—This may be made either from the 
‘oreen’’ bones or from bones which have esSit through 
the digester upEeesure boiler).

to extend this to Australia. 
One of the most picturesque of sea-monsters is a 
member of the whale kind, this being the Killer, or Killer 
— Whale (Orca gladiator), which attains a length of about 
30 feet. “It is one of the Toothed Whales, having large 
conical teeth in both jaws. It is mostly known on this
