inhabitant, that the arrangement 

 of conchology is founded. In 

 early periods, naturalists hesitated 

 whether to construct the arrange- 

 ment from the animal or the shell ; 

 it was, however, very wisely de- 

 termined that it should be from 

 the latter. The greater part of 

 shells are found without the ani- 

 mal in them, and all fossil shells 

 can only be determined by their 

 form. The Linna3an arrangement 

 of shells consists of three orders, 

 namely, Univalves, Bivalves, and 

 Multivales. Univalves consist of 

 shells complete in one piece, as the 

 cyprea, bulla, buccinum, &c. Bi- 

 valves are shells of two parts, or 

 valves, generally connected by a 

 cartilage, or ligament, as the oyster, 

 muscle, cockle, &c. Multivalves 

 are shells consisting of more parts 

 than two, as chiton, lepas, and 

 pholas. Every part of a shell 

 which is connected by a cartilage, 

 ligament, hinge, or teeth, is called 

 a valve of such shell. Of the three 

 orders of shells, the univalves are 

 the most numerous, both in genera 

 and species.

CO'NDYLE. (*coVv\os, Gr. oondylw, 

 Lat. condyle, Fr.) The condyles 

 are bony projections, or eminences, 

 at the ends of bones, as the condyles 

 of the shoulder-bone at the elbow ; 

 the condyles of the thigh-bone at 

 the knee. 



CO'NDYLOID. (from icdvSv\o9 and e?os, 

 form, Gr.) An apophysis of a bone ; 

 resembling a Condyle.

1. A solid figure having a circle 

 for its base, and terminating in a 

 point ; a figure resembling a sugar-

CONFE'BVA. A genus of plants, class 

 Cryptogamia, order Algse. 



CONFEBVITES. Fossil remains of 

 plants belonging to the genus Con- 

 ferva. 



CONFIGUBA'TION. (Fr. Forme exU- 

 rieure, ou surface qui "borne les corps, 

 et leur donne une figure particuliere.) 



1. The form of a body in relation 

 to its various parts, and their 

 mutual adaptation. 



2. The conjunction, or mutual 

 aspect of the planets. 



CONFO'RMABLE. (conforme Fr. conforme, 

 It.) A term used in geology to 

 express parallel strata lying upon 

 each other, or when their general 

 planes are parallel to each other : 

 thus, when several horizontal 

 strata are deposited one upon 

 another, they are said to be in a 

 conformable position, but when 

 horizontal are placed over vertical 

 strata, they are said to be uncon- 

 formalle, so far as regards the 

 horizontal in relation to the vertical 

 strata. 



CONFORMABLY. In agreement with 

 one another. Horizontal strata 

 placed on parallel strata lie con- 

 formally ; when placed on vertical 

 strata, or strata having an incli- 

 nation, or dip, they rest uncom- 

 formably. 



CONFOBMA'TION. (conformatio, Lat. 

 conformation, Fr. conformazione, It.) 

 The form, shape, or structure of a 

 body, as regards the disposition of 

 the various parts, and their relation 

 to each other. 



CONGE'NEBOTJS. (congenereux, Fr.)

1. In anatomy, muscles which act 

 together to produce the same move- 

 ment are called congenerous. 



2. In botany, plants of the same
