ROOM IV. SYNOPSIS OP CONTENTS. 365 



%* With these Cases the collection of minerals terminates, 

 the Table-cases in Booms V. and VI. being devoted to fossil 

 remains. 



It may be useful to the student to know that hi the cabinets 

 we have enumerated, the same mineral species in each Case is 

 indicated by a coloured border corresponding with that of the 

 label on which the name of the mineral is written ; as, for 

 example, the same coloured margin as that on the ticket 

 " QUARTZ," surrounds every specimen of quartz in that Case. 1 



15. Fossil shells of Gasteropodous mollusks, (holostomata 

 and siphonostomata,) from Tertiary and Secondary strata, 

 named and arranged by Mr. Woodward. There are many very 

 fine specimens from the Great Oolite of Minchinhampton. 



A polished slab of a septarium showing displaced sections 

 of shells, (Turritella imbricata,) from the London clay of 

 Western Sussex, (discovered by the Author,) is very inte- 

 resting ; a mass of perfect shells of the same species is placed 

 near it. 



16. Vacant.

 I as Corals, Sponges, <fcc. Many are from the Bradford clay ; 

 I others from the Silurian limestone of Dudley, Wenlock, &c. 



There is likewise a series of the larger forms of Forami- 

 \niferd ; viz. Nummulites, Orbitolites, <fcc. 



18. Fossil univalve shells from tertiary strata ; chiefly 

 [from the Eocene deposits of Grignon, near Paris ; Hordwell,
