may not be those of a single individual. 
The skin of an animal prepared for permanent preservaulon 
should always be accompanied by 7s own skull, even if the rest of 
the skeleton has not been kept. But a skull by itself may be 
worth preserving if the collector gives every possible assistance in 
determining the species to which ib belo ongs. This is best done by 
stating that it is of the same kind as some other specimen, 
obtained at the same time, whose skin is in the collection sent to 
the Museum. If this cannot be done, part of the skin can some- 
times be sent to aid in the determination, and notes may be made 
of the coloration of the living animal. 
In the males of Monkeys, Carnivora and Rodents there may be 
present a loose separate bone in the penis, which should also 
be preserved, dried and fastened to the rest of the skeleton. 
And in some few animals, notably the Cats, the collar-bone is 
rudimentary, and care should be taken that it is not thrown away 
if the limbs are taken off. 
Il.—Cetacea (Whales, Dolphins and 
Porpoises). 
The collection of Cetacea offers special difficulties, but useful 
work may be done if advantage is taken of suitable opportunities. 
Whales and Dolphins are not infrequently stranded on the coast, 
and smaller kinds are sometimes caught in fishermen’s nets. 
No satisfactory way of dealing with the skins of these animals 
is known, and it is accordingly not desirable to waste time in 
preparing skins which can neither be stuffed nor made much use 
of in any other way. The skeleton is the part which is most 
valuable from a scientifie point of view, but it is important to have 
a record of the external appearance of the animal from which it 
was derived. 
In collecting Cetacea, the first thing to do with any specimen 
is to make certain measurements and notes on its external 
appearance. 
The more important measurements to be taken are those 
indicated in Fig. 1, B; but the length of the paddle or flipper (fore 
limb), Tarot along its lower Wonder and the distance between 
the vent and the opening of the reproductive organs should also 
be recorded. 
It should be ascertained whether the mouth contains “ Whale- 
bone’’ (baleen) or teeth. In the former case, note the number of 
blades of baleen* which grow on each side of the palate (Fig. 2), 
and, if possible, the length and breadth of the eet blade. The
