President’s Address. 
the Geological Survey, and much useful information is from 
time to time given to the public, both by communications 
to our Society, and in papers laid before Parliament, and 
published in Blue-books. 
In this way we have learned that considerable quantities 
of the oxides of manganese occur in many parts of the 
Ararat District, both in quartz veins associated with gold, 
and in the alluvial deposits ; that there are beds of lignite 
in numerous localities alternating with, the lower 
strata of clays in the “ deep leads ; ” that the ores of copper 
and load are found in most of the localities where there are 
numerous quartz veins (and, though in small quantities, they 
deserve the attention of the geologist) ; that the sulphide 
and oxide of antimony in large quantities are not restricted 
to Heathcote, but occur in the basin of the Yana, at Ingle- 
wood, at Steiglitz, and elsewhere ; that in the neighbourhood 
of plutonic rocks there are nearly everywhere mingled with 
the drift titanic iron, pleonast, corundum, zircon, and topaz ; 
that chromate of iron and chrome ochre are found in con- 
siderable quantities in the vicinity of basalt on the River 
Loddon ; that pyromorphite is found at Ararat, and that 
lolingite and pyrrhotine are common at Maldon. 
If many of these do not at present add to our national 
wealth, they serve to indicate fields of research for the 
mineralogist. I am also indebted to the department for the 
knowledge of the discovery of fossil bones on McCallum’s 
Creek, near Talbot, by Mr. Hull and Mr. E. J. Bateman, 
who forwarded the specimens now in the National Museum, 
and which I found to belong to the Diprotodon. The Map 
of the Colony is being gradually filled in from the surveys 
made by the Mining Surveyors, which, together with the 
valuable results of the labours of Mr. Ligar’s (the Surveyor 
General’s) officers, will shortly leave nothing to be desired 
as regards the topography of Victoria. 
The great credit of first discovering and practically apply- 
ing a process for photographing maps, &c., on lithographic 
stones, and printing from such impressions directly, without 
the aid of a draftsman, is due to the Surveyor General’s 
(Mr. Ligar’s) department of this Colony, and the first suc- 
cessful steps in the invention were exhibited at a Meeting of 
our Society. Our Vice-President, Mr. Ligar, commenced, 
and is still carrying on, the series of experiments in the
