The Eev. W. Locock, who was introduced to the Club by Mr. Curties, ex- 

 hibited and described a contrivance for securing slides in any position on a 

 turntable. This was accomplished by means of a strip of metal or wood 

 about f th inch thick, fitting by notches on to the screws which fasten the 

 springs, and about |th inch broader opposite one screw than the other. A 

 wedge sliding against this will allow of a badly-centred slide being brought 

 into position, and secured by an excentric button. A depression was made 

 in the centre of the turntable to receive cardboard discs, with holes or rings 

 for guides in making cells. A contrivance for accurately centering objects 

 on a slide was also described and shown, in which the slide could be placed 

 in a wooden trough and adjusted over cardboard slips accurately marked. 

 (See " Science Gossip" for September, 1875, p. 206 for figures and full 

 descriptions.) 



The President thought that anything which contributed to neat mounting 

 would be regarded as a boon. The little contrivance of Mr. Locock for 

 holding the slide upon the turntable, he thought would be found very 

 useful, especially where it was necessary to apply some degree of pressure 

 upon the slide, as, for instance, with a diamond, in which case it would 

 prevent the slip from moving aside during the operation. 



The President said they were also favoured by the presence of another 

 visitor, Mr. Arthur C. Cole, of Liverpool, who had brought to the meeting 

 for exhibition a beautiful collection of physiological specimens, prepared 

 and mounted by himself.
