Lecture.—' 1 Heredity." By Professor A. P. W. Thomas, M.A. 



The lecturer explained the scientific facts upon which the modern theories of 

 heredity are based, illustrating his remarks by carefully prepared diagrams and 

 numerous lantern-slides. 



Especial weight was given to the researches of Weismann, and to the totally 

 new light which the tardy recognition of Mendel's laws had thrown upon the sub- 

 ject. He then passed on to the subject of eugenics, now becoming so prominent, 

 and pointed out what could be reasonably expected from it, and what effects of 

 importance on the physical and mental characters of mankind might be anticipated 

 if the principle ever came within the range of practical achievement. 



A very hearty vote of thanks was passed to Professor Thomas at the close of the 

 lecture.

Lecture. — "Whirling Discs and their Uses." By Professor F. D. 



Brown, M.A. 



In this lecture Professor Brown discussed the principles of gyroscopic motion, 

 pointing out that the gyroscope, which at one time was regarded as little more than 

 a scientific toy, though a very interesting one, had now, through the modern 

 development of mechanism, been found to have many possibilities of application to 

 ships, motor-cars, aeroplanes, and railways, to say nothing of minor examples. A 

 great number of experiments with different forms of gyroscopes, &c, were exhibited 

 to the meeting, and fully explained. A model of the Brennan mono-rail was also 

 exhibited, and made to travel along a wire stretched across the lecture-room. On 

 the motion of the President, a vote of thanks was passed to Professor Brown by 

 acclamation.
