The pink epidote known as thulite is described by Pisani from 
near Traversella, in Piedmont, where it occurs in small veins, asso- 
ciated with tale and green hornblende in a granite rock. 
The same chemist also announces a new locality for the rare 
mineral Bustanvite, a silicate of manganese, containing lime, hitherto 
found only in Mexico. The specimen analysed by Pisani came 
from Monte Civillma, between Schio and Valdagno, in Italy. 
A visit to the locality of the aluminium ore Bauwite has 
enabled M. Virlet d’Aoust to present to the Geological Society of 
France certain “ Mineralogical and Geological Notes on the Pisolitic 
Aluminous Iron Ore of Mouries, called also Les Baux” (“Notes 
Minéralogiques et Géologiques sur le Minerail de fer Alumineux 
Pisolithique de Mouries, dit aussi des Baux”).* 
Professor Maskelyne announces{ that he has received from Mr. 
Talling, of Lostwithiel, a new Cornish mineral, described as a 
finely-granular greenish-blue substance, which proved on analysis 
to be “a hydrated aluminic (with traces of calcic) silicate, tinted 
rather deeply with a cupric silicate. It is doubtless an opal allo- 
phane, the Saltzburg variety of which mineral it closely resembles.” 
The literature of mineralogy has been recently enriched by the 
publication of the first volume of an admirable ‘ Treatise on Physical 
Mineralogy, by Dr. Albrecht Schrauf, of Viennat The present 
volume—devoted exclusively to Crystallography and Mineral-Mor- 
phology—contains an interesting outline of the history of Crystal- 
lography and Crystallogenesis, followed by several chapters on 
Homceomorphism and Pseudomorphism. Considerable space is then 
devoted to Theoretical Crystallography, the system adopted bemg 
that of Miller and Neumann, with certain modifications introduced 
by the author. The different forms of goniometer are then 
described, and ample instructions given both for taking measure- 
ments and for reckoning the results. At the close of the volume is 
a useful table giving a comparative view of the crystallographic 
symbols of different authors. The present work is intended as a 
companion to the author's ‘ Atlas der Krystall-formen des Mineral- 
reiches,’ an elaborate work, to be completed in twenty parts, of which 
the first appeared a few months ago, comprising ten beautifully 
executed plates of crystalline forms. In these comprehensive works 
Dr. Schrauf appears to be doing for Physical Mineralogy what 
Rammelsberg has already done for the Chemistry of the Science.
