' REPORT OE THE 
The majority of the new specimens were presented by the 
Honorary Curator; they having formed a portion of the 
duplicates of the Tennant Collection. At present the additional 
specimens are in drawers, hut it is intended to introduce some of 
the best into the mineral cabinet, and at the same time to 
remove some of the inferior specimens of the old collection. It 
may he convenient also to complete the arrangement and re¬ 
labelling of the entire collection, which was commenced some 
time ago. 
Amongst the minerals referred to in the preceding paragraph 
are fine specimens of Tyromorpliite^ Mimctesite (variety, 
Kamjiylite), well ciystallized Crocoisite, Hemimorphite, and 
Proustite. With these additions the suite of Silver, Lead, and 
Zinc Minerals may he considered thoroughly representative. 
Some well crystallised specimens of Dolomite, Celestine, 
Sulphur, and Casdterite are especially deserving of notice ; 
and there are crystals of Blende which exhibit the characteristic 
striations on the faces, and thus possess considerable interest 
from a crystallographic point of view. 
But few additional specimens of Silicates were acquired, as 
the orioinal collection was found to be tolerably rich in this 
O ^ 
respect. 
The chief deficiency is in the triclinic felspars which, with 
the exception of Lahradorite, are poorly represented. It will 
be remembered that the minerals of the quartz group and the 
silicates were arranged and re-labelled by tlie present Honorary 
Curator a year or two ago. 
The following species, added during the past year, were 
previously unrepresented in the collection : — Psilomelan, 
PJwdocliromte, dMelanterite, Erythrite, CUnoclase, Realgar, 
Atacamite, Domeykite, DathoUte. 
The Honorary Curator of Comparative Axatomy has to 
report that the collection under his care is in good order. The 
additions during the past year have been of a minor character.
