XLII. ROYAL SOCIETY OF CANADA. * 
Prof. Lockwood, of Princeton, N. J., communicated a paper on “ Canadian Earthquakes,” in which 
he gave dates and particulars of every shock of earthquake reported in Canada during the past four 
years, which showed that these shocks are more frequent than is generally supposed, and that they 
appear to be connected in a remarkable way with certain seasons of the year. 
Mr. Walter Ferrier reported the discovery at Rainbow Falls, near Au Sable Chasm, N. Yj of 
Potsdam sandstone bearing animal impressions belonging to the genus Gyrichnites, already proposed 
for a similar impression from the Devonian of Gaspé by Mr. J. F. Whiteaves, of the Geological Survey. 
The results of analyses of soils from the fertile orange belt of Florida, from the former bed of 
the St. Lawrence near Montreal and from a section of the N. W. Territory were submitted by Dr. 
J. Baker Edwards. 
Messrs. E. Murphy and Wm. Muir presented the results of a microscopic study of the suctorial 
organs of the mosquito, and the measurements of the various structures of this insect. 
In addition to monthly meetings for the reading and discussion of papers, the society has, during 
the past year, published four numbers of the Canadian Naturalist, and given a course of six free 
popular scientific lectures. Of late it has fallen to the lot of our society to represent, to a certain 
extent, in certain circles, the Dominion. It took the initiative in inviting the American Association 
for the Advancement of Science to hold its meeting in 1882 in Canada, and was foremost in receiving 
and entertaining the association when it met in Montreal in August last. Certain specimens from 
the society's museum were selected to form part of the Canadian exhibit at the International Fish- 
eries Exhibition in London, and one of its members was commissioned by the Government to execute 
drawings of a number of Canadian fishes for the same exhibition. Recently our society has learned 
that its efforts, along with those of other societies, to induce the British Association for the Ad- 
vancement of Science to meet in Montreal in 1884, are likely to be successful. 
It will thus be seen that during the past year our society has contributed somewhat to the 
general fund of scientific truth, has endeavored to present well-established facts of science to the 
public in a popular manner, and has done not a little to bring the condition and resources of our 
Dominion before the scientific congresses of Britain and America. 

Mr. JAMES FLercuer read the following Report of the Entomological Society of Ontario : 
In response to the invitation received by the Entomological Society of Ontario to send a 
delegate to the meetings of the Royal Society of Canada, the Council of management gladly avail 
themselves of the privilege so accorded them of being represented on this occasion. 
As their delegate, I shall endeavour to submit for your information, in as brief a manner as 
possible, some of the main features relating to the origin and progress of the society, now so well 
known as the Entomological Society of Ontario. It was organized in 1863 under the name of the 
Entomological Society of Canada, by a few naturalists living in different parts of the provinces, who 
met together at Toronto for this special purpose. Its membership at first was only sixteen, and this 
number ineluded all those then known to be interested in the study of insect life in Canada. From 
this small beginning the society has steadily increased until its membership now reaches upwards 
of 500. 
The benefits of organization and united effort were soon manifested by the rapid accumulation 
of valuable facts relating to scientific and economic entomology. Formerly this material was from 
time to time published in the pages of the Canadian Journal; but the increased interest in the work 
of the society, and its larger membership rendered it necessary in a few years for it to establish a 
periodical of its own, entirely in the interests of entomology. On August Ist, 1868, appeared the 
first number of The Canadian Entomologist, a monthly periodical which has from that time forward 
been regularly issued, and which was for some years the only publication on the continent of 
America devoted solely to this important branch of natural science. It has now reached its 
fifteenth volume. From the outset its pages have been entirely filled with the records of original
