1899] ENTOMOLOGICAL SOCIETY. 45 



A discussion on the subject of the purchase of a Magic Lantern was introduced by Mr. 

 John Law, who thought that the Society ought to have one for exhibition purposes. Prof. 

 Lochhead gave some information regarding the cost of a lantern and slides. After remarks 

 by Messrs Dearness, Fletcher, Bethune and Bowman, it was resolved that "The considera- 

 tion of the question of purchasing a Magic Lantern be referred to the library committee 

 to obtain all the information possible about it during the year, and that they be author- 

 ized to purchase slides and to rent a lantern at such times as may seem advisable." 



The next business of the meeting was the election of officers for the ensuing year, 

 which resulted as on page 2. 



Honorary Members. — The following gentlemen were unanimously elected Honor- 

 ary Members of the Society : — Dr. L. O, Howard, United States Entomologist, Washing- 

 ton, D. C. ; Professor John B. Smith, Sc. D., Rutgers College, New Brunswick, N. J.; 

 Professor P. M. Webster, Wooster. Ohio ; Professor H. P. Wickham, Iowa City, Iowa. 



REPORT OF THE GEOLOGICAL SECTION. 



The Geological Section of the Entomological Society of Ontario begs leave to present 

 the following report : 



The meetings of the section were held weekly as usual, and a gratifying amount of 

 interest in the study of geological science was evinced. 



The noteworthy features of the year's study weie the following : (a) An examination 

 of local geology, including discussions respecting the origin of the flowing suiphur springs ; 

 (b) an investigation of the extent of local peat beds ; (c) visits to Kettle Point ; (d) 

 visits to Western Ontario oil fields ; (e) and a very interesting account of a visit to the 

 Parry Sound district. Besides these visits Mr. Percival revisited the Strontium cave at 

 Put-in- Bay Island, Ohio. Mr. Goodburn also visited the Lake Superior copper region s 

 and will report on it. 



Local Geology. 



London is situated in a wide valley eroded by the river, who3e two main branches 

 unite at this point. It is probable that the coarse of the river has been changed here 

 more than once, and that at one time the north branch flowed east by way of Carling's 

 Creek and joined the east branch on the eastern limits of the city, and that the channel 

 of the east branch is now several hundred feet south of its ancient location. The boulder 

 clay is here deeply overlaid by clean water-washed sand, with quicksand in many places. 

 The distance to bedrock is about 120 feet in the lower parts of the city. On the high- 

 lands surrounding it is much more. At Mt. Brydges, 20 miles west, it is 300 feet. Thus 

 the depth of the drift and boulder clay is a feature of the locality. In the eastern part 

 of the city pure water is obtained abundantly in the drift, but lower down than the 

 boulder clay no water suitable for domestic use in quantity has been found until great 

 depths are reached. On the other hand, at the Forks, and generally in the western 

 portion of the city, sulphur springs are found in the upper rock strata. A sulphur spring, 

 flowing 40 cubic feet per minute, struck about thirty years ago, continues to flow in 

 undiminished volume. The water rises to a height of 24 feet above the surface, and 

 formerly was utilized to turn a wheel and made to do useful work at street watering 

 until the sulphuretted hydrogen created a nuisance on the streets and in the shops where 

 iron goods were sold. Analysis of the water shows it to be highly mineralized, and it is 

 reputed to be valuable as a remedy in cases of certain skin dh- eases, particularly eczema. 

 Facilities for bathing have been provided, and are patronized by the general public. The 

 quantity of sulph. hydrogen is not large, though from its offensive odour it would appear 

 to be exceedingly abundant. The gas probably has its origin in the decomposition of the 

 gypsum beds of the Onondaga group, and coming from higher levels to the eastward flows 

 as before noted. The temperature of the water is 48°, and in summer seems icy cold. 

 It is scarcely possible that it comes from any great depth, as if it did so its temperature 

 would be considerably higher.
