long, deeply corrugated; lobes about 4o lanceolate 3 lines 
long ; corolla of normal colour companulate ; tubes extend- 
ing rather more than }in. beyond the calyx-lobes, fringed 
by the numerous 40 to 50 rather curly lobes. Stamens, as 
many as corolla lobes, perfect normal, forming a close ring 
in the throat. Styles: one appearing to be normal, the 
others more or less adnate to each other in three bundles. 
Bouvardia is a genus of Rubiacez, tribe Cinchenae. 
Its 20 to 30 known species are principally Mexican, and 
the rather numerous garden forms are great favourites with 
Australian florists. 
“On NATIVE ZINC IN QUEENSLAND,” by E. B. Lindon, 
A.R.S.M., etc.—Professor J. W. Dana, in his “System of 
Mineralogy,” edition 1883, says that native zinc is ‘“ reported 
by G. Ulrich as having been found in a geode in basalt near 
Melbourne, and that the piece weighed 43 oz., was incrusted 
with smithsonite, aragonite, and some cobalt bloom.” Native 
zinc was “‘also said to occur in the gold sands of the Mitta- 
mitta River, north of Melbourne, along with topaz, corun- 
dum, &c.; a single piece, according to L. Becker, having 
been found which contained traces of cadmium and other 
metals. (L. Becker, in Trans. Phil. Inst., Victoria, 1856, 
and Jahrb. Min., 1857, 312, 698; G. Ulrich, in B. H. Ztg., 
XVIII., 63). It should be stated that the zinc said to come 
from the Melbourne basalt was found by a quarryman and 
not by a scientific observer, and that therefore there may 
be an error with regard to its actually having been taken 
from the basalt.’’ Professor Dana then makes the pertinent 
remark that ‘the existence of native zinc seems still to 
need confirmation.” 
From Vol. XI., p. 234 of 3rd series of the American 
Journal of Science, I take the following note :—‘‘ On the 
occurrence of Native Zinc. (Letter to one of the 
Editors)—Mr. W. D. Marks, of Chattanooga, Tennessee, 
announces the occurrence of fragments of metallic 
zinc in the soil along the course of a vein intersecting 
the blue limestone of Sand Mountain, in the north-eastern 
corner of Alabama. The circumstance is supposed to 
indicate that the metal came originally from the adjoining 
rocks. Further than this, he states that pieces of metallic
