would be drawn out into ellipses. Secchi, Daws, and the Lick observers 

 have seen them occasionally of this form. Satellite I. has been some- 

 times seen apparently double, more light being reflected from near the 

 ends than at the centre of the ellipse. 



Mr. Elvins referred to many observations of satellites, when near the 

 limb of Jupiter, having been seen to disappear and reappear, etc. He 

 explained this by supposing the light to undergo refraction in passing 

 through gaseous matter recently thrown from the planet and moving in 

 orbits near the primary. He thought it probable that all the satellites 

 were originally thrown from the planets by the combined action of the 

 tangential force caused by the planets' rotation, the molecular motion of 

 the gases in the atmosphere of the planet, and by projected matter 

 thrown from the Jovian volcanoes into space.

Mr. A. F". Hunter, M.A., read a paper on " British Immigration into 

 Upper Canada, 1825-1837." The population of Upper Canada at the 

 close of the war of 1812-14 was less than 100,000. This had increased 

 fourfold by the time of the outbreak of the rebellion of 1837, the increase 

 having been chiefly due to British immigration. Amongst the causes 

 that produced this rapid influx of immigrants during the period were 

 these: — i. Attention in Britain was turned towards Upper Canada by 

 many books of travel, the writers of which visited the country and 

 published their travels on returning home. No other period has yielded 

 so much literature relating to the country and its resources. 2. The free 

 grant land policy was adopted here at an earlier date than in some of 

 the States. Besides this, an order-in-council in 18 18, imposing settle- 

 ment duties on the U. E. Loyalists, militia, discharged officers and 

 soldiers, pensioners, and all others receiving free grant lands after that 

 date, had the effect of preventing them from holding land on speculation, 

 and thus stimulated settlement. 3. At the passage of the Catholic 

 Emancipation bill in 1829, despondency fell upon the Irish Protestant
