HAD 



A group of rocks more recent than 

 the Pleistocene, and by some 

 authors called " Post-pleiocene," 

 in which all the fossil shells are 

 still found living on the globe, 

 though not always in the immediate 

 neighbourhood of the places where 

 they are found fossil. The quater- 

 nary, or Post-pleiocene formations 

 consist of irregular deposits of clay, 

 sand, and gravel, with which, in 

 many cases, are associated huge 

 blocks of rock, that have been 

 transported sometimes from vast 

 distances. 



QUI'CKLIME. This may be obtained 

 by exposing chalk, limestone, or 

 any calcareous substance, for a 

 length of time, to a full red heat, 

 whereby the carbonic acid and the 

 water, which were previously in 

 combination, are expelled. 



QUI'NATE. In botany, applied to 

 compound leaves when composed 

 of five leaflets. 



QUINQTTA'NGULAR. (from quinque, five, 

 and angulus, an angle, Lat.) 

 Having five corners or angles. 



QUINQUECA'PSULAR. (from quinque, 

 five, and capsula, a capsule, Lat.) 

 In botany, applied to a flower 

 having five capsules. 



QUINQUEDE'NTATE. (from quinque, 

 five, and dens, a tooth, Lat.) Five- 

 toothed. 



QTJINQUEFO'LIATED. (from quinque, 

 five, and folium, a leaf, Lat.) 

 Having live leaves. 



QUINQUELO'BATE. | (from quinque, five, 



QTJINQUELO'BED. ) and lobus, a lobe, 

 Lat.) In botany, applied to parts 

 which are divided to the middle 

 into five distinct parts or lobes. 



QUINQUELO'CTTLAII. (from quinque, five, 

 and loculus, a cell, Lat.) Five- 

 celled ; having five cells. 



QUINQTJEVA'LVTJLAR. (from quinque, 

 five, and valves, doors or valves, 

 Lat.) Having five valves. 



KACE'ME. (racemus, Lat. a bunch of 

 berries.) A term used in botany 

 to express a kind of inflorescence, 

 when all the buds of a newly-formed 

 axis unfold into flowers, each having 

 stalk ; a raceme consists of nume- a 

 rous flowers, rather distant, each 

 on its own proper stalk, and all 

 connected together by one common 

 peduncle. 



EADIA'TA. The name given to the 

 fourth great division of the animal 

 kingdom, in consequence of the 

 radiated form of the body which 

 is so apparent in some of the classes 

 which compose it. This division 

 comprises five classes, namely, 

 Echinoderma, Acalepha, Polypi- 

 phera, Poriphera, and Polygastrica. 

 The radiata are amongst the most 



frequent organic remains in the tran- 

 sition strata, and they presentnume- 

 rous forms of great beauty. Eadiata 

 have also been called zoophyta. 

 They form the lowest division of the 

 animal kingdom, having skeletons 

 as various as the forms of the 

 animals. " The muscular system, 

 so essential to all the voluntary 

 and involuntary movements of the 

 higher classes, entirely disappears 

 in the class of radiated animals, 

 and with it every trace of nervous 

 system, which we are apt to suppose 

 essentially connected with all the 

 motions and functions of animals. 

 In the majority of radiated animals 

 the blood-vessels also cease to exist, 

 and with them all circulating 

 motion of the blood. "
