THE NORTHERN ZOOLOGICAL GALLERY. 
FIRST ROOM. 
This room may be for the present considered as an appendage to the 
two foregoing. 
The Wall Cases on the side of the room contain a collection of 
Nests of Birds and Insects, exhibiting the architecture of these animals. 
The Table Cases. The tubes of Annulose Animals, the casts 
of the interior cavities of Shells, and various specimens of shells, illus¬ 
trative of the diseases and malformation of those animals. 
Tables 1, 2 contain the shelly tube formed by the Serpulce, which 
have often been confounded with shells. The tubes of sand, agglu¬ 
tinated together by the juices of the animal, formed by the Amphitrite 
Tables 3, 4 contain specimens of shells, exhibiting the different 
sizes of different specimens in their adult age, the changes of form which 
occur in the shell during the growth of the animal, the changes 
which take place in the cavity of shells, the manner in which shells 
are mended by the animal after any injury, and also how the animal 
covers any excrescence which attaches itself to a shell, or removes any 
part which is in the way of its enlargement. 
Tables 5, 6 contain a series of plaster casts of the interior cavities 
of different shells of living mollusca, to assist in determining the 
casts of fossil species often found in rocks. 
Tables 7, 8 contain a series of models on an enlarged scale, and 
some specimens of minute bodies, formerly called Nautili , but now 
formed into a group under the name of Foraminifera. 
In one of the Cases are the shells used for cutting cameos, showing 
the places where they are cut from. 
SECOND ROOM. 
The Wall Cases round the room contain the collection of exotic 
stuffed Reptiles and Batrachian Animals, and the Table Cases 
the hard part of Radiated Animals, including the Sea Eggs, Sea 
Stars, and Encrinites. 
The Wall Cases 1—10. The Lizards. 
The Cases 1—5. The Monitors of Africa and India. In both 
countries they are venerated by the natives, who assert that they give 
notice of the approach of crocodiles, by hissing when they perceive one 
of those animals; hence their name. 
Case 5. At the bottom are the Heloderms from Mexico, which, unlike 
any other lizard, have a groove in the back of the teeth like serpents. 
They are said to be poisonous; but this may be a mistake, for ignorant 
persons are inclined to believe that all reptiles are dangerous. 
Case 6. At the upper part, the Safeguards of the tropical parts
