NOTES ON THE GEOLOGY OF NEWFOUNDLAND—WESTON. 151 
Laurentian of certain forms which resemble Stromatocerium 
rugosum, one of the Protozoa of the Silurian. This peculiar 
mineral aggregate (7), received from Sir W. E. Logan and J. W. 
Dawson the name Hozoon Canadense. Literature enough to 
fill a cart has been published for and against this supposed organ- 
ism, among which Dawson’s Dawn of Life is the most interesting. 
With the exception of Sir J. W. Dawson, probably no one has 
done more work at this supposed fossil than the writer, who has 
prepared hundreds of microscopic sections, micro-photographs, 
micro-drawings, illustrative collections for the Paris, London, 
Philadelphia and late Chicago Expositions, and for other public 
and private collections; still he could never make up his mind 
that Hozoon Canadense is of organic origin. Mr. Billings, late 
paleeontologist to the Geological Survey of Canada, pronounced 
strongly against the organic character of Hozoon. I have 
frequently conversed with Dr. Selwyn, Mr. Whiteaves, Dr. Ami, 
Dr. Ells, the late Mr. Vennor (who obtained the Tudor specimens), 
and other members of the Canadian Survey, but none of these 
gentlemen ever admitted that Kozoon is a fossil. However 
Eozoon will always remain an interesting subject for students 
in paleontology and mineralogy. 
The Huronian.—In Canada the Huronian system represents 
a thickness of about 20,000 feet of strata consisting of quartzites, 
slates, limestones, sandstones, chert, jasper, conglomerates and 
other rocks in which no fossils have been found. While import- 
ant measures represented in Canada are missing in Newfound- 
land, there is a great similiarity between the Huronian of the 
two countries. Its exact thickness in Newfoundland does not 
appear to be known. Murray gives a section of 11,370 feet of 
strata consisting of diorites, quartzites, Jaspers, slates, conglomer- 
ates, sandstones, ete. Like our Canadian Huronian, these rocks 
in Newfoundland have yielded no fossils unless we consider 
Billings’ Aspidella terranovica, and two other obscure forms 
mentioned by the same writer as organic. 
In his report for 1868 Mr. Murray speaks of these forms 
lescribed by Billings—Palzeozoic Fossils, Vol. I, Part I., and also
