ANNIVERSARY ADDRESS, 19 
A competent critic of this work says of it, in the Sydney Morn- 
ing Herald, that it is the most valuable portion of Mr. Clarke’s 
labours, and “ represents in epitome the results of the work of his 
life. We refer more especially to the appendices which contain 
all that is known of the Paleontology of New South Wales. That 
knowledge has hitherto been scattered many works, all of them 
difficult of access to the general reader, and some of them becoming 
very scarce.” As there was no sufficient collection of typical 
fossils for comparison in the Colony, Mr. Clarke had to send his 
specimens to other countries for identification. Respecting this, 
he narrates, in the appendix to “ Remarks, &c.,” the many efforts 
he made to obtain the opinions of competent men on his collee- 
tions, and the difficulties and disappointments he met on every 
hand. “In this extremity,” he proceeds, “I consulted Professor 
T. Rupert Jones, who recommended me to seek aid from Professor 
de Koninck of Liege, who * * has most ably, indefatigably, and 
willingly accomplished it, to his own reputation as I hope and 
believe, and certainly with muck honourable acknowledgment or 
myself. I had myself begun the work in a small way by making 
drawings to scale of more than 1,200 individual specimens collected 
by me from the carboniferous beds. * * * They were never 
published, and it was the feeling that it was a work beyond my 
own powers to do justice to it, coupled with want of pecuniary 
means and of leisure from my parochial duties, that induced me 
to look to professional and acknowledged authorities in Palwonto- 
logy, out of the Colony.” 
Following up his examination of Mr. Clarke's specimens, 
Professor de Koninck has recently brought out two volumes on 
the Paleozoic Fossils of New South Wales, with many litho- 
gtaphie illustrations. A reviewer of this work in the Herald 
Properly points’ to it as a conspicuous monument to the zeal and 
a Publication of this work, and the specimens named and figured by
