BEETLE, 

 which they are associated, and similar to 

 them both in form and dimensions. The 

 Beekites, as tliese rounded masses are called, 

 vary in diameter from half an inch to a foot, 

 but they rarely exceed from three to six 

 inches in diameter. Their surfaces are com.- 

 posed of Chalcedony, generally arranged 

 in tubercles varying in size from a pin's 

 head to a pea, each of which is not unfre- 

 quently surrounded by one or more rings, 

 and occasional!}' the same ring invests two 

 or even more tubercles. 



When broken the interior is most com- 

 monly found to be calcareous, and in a decom- 

 posing state. Occasionally the nucleus has 

 entirely decomposed ; in which case only 

 a few grains of matter remain within the 

 crust, and the Beekite will float in water. 



Localities. — British. A very few specimens 

 have been found in Carboniferous Limestone, 

 near iSidcot, in Somersetshire, and in the 

 north of Scotland. They are, however, 

 found in every part of " the Conglome- 

 rate of Torbay, in Devonshire, from Good- 

 rington Sands on the south, to Tor- Abbey 

 Sands on the north; but they are con- 

 siderably more abundant at Livermead 

 Head, and at and near Paignton Harbour 

 than elsewhere in the district. — Foreign. 

 Beekites have also been found in Austra- 

 lia, in Triassic Conglomerates, and on the 

 banks of the Nerbuddah in India. 



Name. After Dr. Beeke, dean of Bristol, 

 by whom they were first publicly noticed. 



Beetle or Bettle-stones. Names 

 sometimes given in S. Wales to septarian 

 nodules of Clay Ironstone from the Coal- 

 measures.

Bell- metal Ore. A name given to Tin 

 Pyrites, from its resemblance in appearance 

 to bronze, or bell- metal. 



Belonit, Glocker. SeeAiKENiTE, 



Beraunite, Breithaupt. A variety of 

 Delvauxene, resulting from the decomposi- 

 tion of Vivianite. It occurs foliated and ra- 

 diated, with one perfect and one imperfect 

 cleavage. Colour hyacinth-red, or reddish- 

 brown. Streak reddish, ochreous-yellow.

Soluble in muriatic acid. 



Localities.— English. Huel Jane, near Tru- 

 ro in Cornwall, in scaly and brittle masses, 

 associated with Vivianite on Eisen-nickel- 

 kies. — Foreign. Near Beraun (whence the 

 name Beraunite) in Bohemia, in Limonite. 

 Near Kertch in the Crimea.

Foriins a bitter solution with cold alcohol. 

 A resin of a clear red colour is obtained 

 by evaporation, and remains soft and viscid 

 at the ordinary temperature. 



Locality. It forms a lake like the Pitch - 

 lake of Trinidad (see Asphaltum) in the pro- 

 vince of St. Juan de Berengela (whence the 

 name Berengelite), about one hundred miles 

 from Arica in Peru, and is used instead of 

 pitch for paying boats and vessels.
