nant, may not be fo fmooth as the furface of oil, fo that the 

 wind may more eafily catch into the inequalities of the 

 former than the latter. Hence it is that the effeft of the 

 wind upon waves may in a great degree be prevented or 

 moderated, by fpreading a thin film of oil on the furface of 

 the water. For an account of this operation and its effefts,

Waved Hair-Grafs, in Agriculture, a fort of grafs which 

 is found to be pretty productive on mountain heathy lands, 

 and which abounds pretty much in nutritive matter, but 

 which lofes confiderably in its weight in drying, according

 Woburn. See Aira Flexuofa. 



WAVELLITE, in Mineralogy, a mineral firft difco- 

 vered at Barnftaple, in Devonfhire, by Dr. Wavell, and 

 fince found in various other fituations. From its appearance, 

 it has been claffed by Mr. Jamefon as a member of the 

 zeolite family. See Zeohte. 



Wavellite occurs in a botryoidal, flalaftical, and globu- 

 lar form ; alfo cryftallized in very oblique four-fided prifms, 

 flatly bevelled on the extremities : the bevelling planes are 

 fet on the obtufe lateral edges. The prifms are fometimes 

 deeply truncated on the obtiife lateral edges. Wavelhte 

 occurs alfo in fibres, or acicular prifms, diverging from a 

 common centre, and either feparated or adhering laterally to 

 each other, compoiing hemifpherical concretions of various 

 fizes, to the magnitude of a bullet. The luftre of wavellite 

 is pearly, more or lefs fhining. The colour is yellowifh- 

 white, greyifh-white, and greenifh-white ; it is tranflucent. 

 This mineral is brittle, and, according to profeffor Jamefon, 

 it is fufBciently hard to fcratch quartz : others afcribe to it 

 a lower degree of hardnefs. Before the blow-pipe it be- 

 comes foft and opaque, but neither decrepitates nor fufes. 

 It is foluble by the affiftauce of heat in the mineral 

 acids, in which it effervefces and leaves very little re- 

 fidue. The fpecific gravity of wavellite varies from 2.22 

 to 2.70. 



The moft remarkable peculiarity of this mineral is its 

 compofition ; wavellite being nearly a pure hydrat of alu- 

 mine ; but fome fpecimens contain a trace of fluoric acid. 

 When fragments of the Englifh or Irifh wavelhte are laid 

 upon a glafs plate, and a drop of fulphuric acid is added, 

 the glafs is flightly corroded on the application of heat, in- 

 dicating the prefence of the above-mentioned acid. 



The conftituent parts of wavelhte are given as under :

Wavellite occurs in veins in the granite of Cornwall, with 

 fluor-fpar, quartz, tin-ftone, and copper pyrites. At Barn- 

 ftaple, in Devonftiire, it occurs in loft flate. Several mi- 

 neralogifts confider wavellite as a variety of the fame mineral, 

 which Hauy has called diafpore.
