XX viii PROCEEDINGS. 



THIRD ORDINARY MEETING. 



City Coimcil Chamber, City Hall, Halifax, 13th January, 1896. 

 The PRESIDENT in the chair. 



A paper by PROF. A. E. COLDWELL, entitled : " Notes on. the Super- 

 ficial Geology of Kings County, N. S.," was read by the Corresponding 

 Secretary. (See Transactions, p. 171). 



The paper was discussed by DRS. MURPHY and GILPIN, and MESSRS, 

 BLACK, HEMEON, Me KAY and BISHOP. 



PROF. J. G. MACGREGOR read a " Note on Newton's Third Law of 

 Motion." In former papers (Trans. Roy. Soc. Can., vol. x, sec in, p. 3, 

 (1892) and Phil. Mag. ser. 5, vol. xxxvi, (1893), p. 241) he had 

 endeavoured to show that the attempt supposed by some writers to 

 have been made by Newton and actuall} 7 " made by Maxwell and Lodge, 

 to deduce the third of Newton's Laws of Motion from the first, was 

 unsuccessful, the reasoning by which the deduction was made being 

 fallacious. In the present paper attention was directed to the attempt 

 made by Mr. R. T. Glazebrook. F. R. S., in his Elementary Text Book 

 of Dynamics (Cambridge University Press, 1895, p. 151) to re-state 

 the deduction in a new form, the object of the paper being to show that 

 Glazebrook's deduction involved the same fallacy as those of Maxwell 

 and Lodge.

 one face a number of very distinct and beautiful dendritic markings 

 representing very closely in general outline the figures and color of some- 

 of the finely sprayed, red seaweeds for which they were popularly 

 taken. But, by the ordinary blowpipe tests, the simulated fronds of the 

 red alga turned out to be an oxide of manganese instead of a fossil, and
