FAS 



great mass of fossil shells which 

 these beds contain, differ from those 

 of the Paris basin : in nearly 400 

 species, there are only about 20 

 identical with the Paris fossils. 

 The terrestrial and river shells are 

 in the same state of mineralization 

 as the marine shells. The bones of 

 the mastodon, rhinoceros, and hip- 

 popotamus, are in the same state of 

 preservation as those of whales, and 

 other cetaceous animals, with which 

 they are intermixed. They are 

 coated with marine polypi and 

 serpulse, which proves that they 

 were long covered by a tranquil 

 and stationary sea. These faluns 

 are distinct from the tertiary beds 

 of the Seine, and more recent than 

 any of them ; but they are them- 

 selves the lowest term of a new 

 system, more important, and more 

 extensive, than the formations of 

 the Paris or London basins, and 

 which has been continued to the 

 present epoch, during all the nu- 

 merous up-heavings of the ground, 

 the changes in the relative level of 

 seas and continents, and the suc- 

 cessive modifications of organic 

 beings. 



FABCILITE. Farcilite is the prevailing 

 rock about Manresa in Spain. 



FARI'NA. (Lat.) Meal; flour: in 

 botany, the pollen, or dust of the 

 anther. The pollen, or farina, is 

 contained in the anther. In dry 

 and warm weather the anther con- 

 tracts and bursts, when the pollen 

 is thrown out. From microscopic 

 observation we find each particle 

 of dust to be generally a membra- 

 nous bag, either round or angular, 

 smooth or rough, which on meeting 

 with any moisture instantly bursts 

 with great force, and discharges a 

 subtile vapour. 



FA'RINOSE. In entomology, having 

 the surface covered with dust, re- 

 sembling flour, which the slightest 

 touch will remove. 



FA'SCIA. (Lat.) The tendinous ex- 



pansion of a muscle, inclosing others 

 like a band. 



FA'SCIATED. Filleted, or enclosed with 

 a band. 



FA'SCICLE. (fasiculus, a little bundle, 

 Lat.) A bundle, or little bundle : 

 applied to flowers on small stalks, 

 when many spring from one point, 

 and are collected into a close and 

 level bundle at the top; as the 

 sweet-william. 



FASCI'CTJLAB. (fascicularis, Lat.) Uni- 

 ted, or growing together, in a clus- 

 ter, or tuft, as the larch, and some 

 species of pine; applied also to 

 roots, when many tubes proceed 

 from the same centre, shooting forth 

 in an elongated form. 



FASI'CULATED. Arranged in small 

 bundles. In mineralogy when the 

 crystals are collected, as it were, 

 into bundles. 



FASCIO'LA. The fluke- worm. A genus 

 of internal worm belonging to the 

 order Parenchymata, family Trema- 

 dotea. There are many species; 

 they are furnished underneath the 

 body, or at its extremity, with 

 organs resembling cupping-glasses, 

 by which they adhere to the viscera. 

 In this genus is included the Distoma 

 hepatica, or Fasciola Hepatica of 

 LinnaBus, which so infests, and is 

 so common in, the hepatic vessels 

 of sheep. 



FASCIOLA'RIA . A subf usiform univalve, 

 channelled at its base, without any 

 projecting sutures, and having two 

 or three very oblique folds on the 

 columella. Parh'nson. 



FASCIOLI'TE. Asubcylindrical, shelly, 

 or bony body, about half an inch in 

 length, rather tapering at the ends, 

 and formed by the spiral arrange- 

 ment of perpendicular, concamer- 

 ated tubes, the tapering end of 

 which is obliquely and transversely 

 folded on that of the preceding one. 

 The tubes are seen to be distinct, 

 and, where the outer surface has 

 been removed, the concamerations 

 are perceived, resulting from the
