From Mr. P. T.Lewis. 



Mr. Curties exhibited Mr. Turner's chromoscope, showing some 

 photomicrographs taken under low powers, and exhibiting the 

 natural colours of the objects when seen through the instrument. 



Messrs. Watson exhibited a new school microscope specially 

 designed for educational work. It had no fine adjustment, but 

 had a very well made coarse adjustment, an inclining body very 

 firmly and rigidly constructed, and standard fittings for the 

 substage. They also exhibited their new holoscopic eyepiece, 

 which, by a simple arrangement for altering the distance between 

 the field lens and eye lens, could be adjusted to compensate the 

 corrections of the objective ; a scale on the side enabled the best 

 position for correcting any particular objective to be noted. 



The thanks of the Club were voted to Messrs. Curties and 

 Watson for their exhibits. 



Mr. Karop thought Messrs. Watson were to be congratulated 

 upon producing a microscope of such excellent quality at so low 

 a price as c£3. He remembered that the first microscope he 

 possessed cost about the same, and was very poor and inferior 

 in comparison to this, which was really strong and extremely 

 well made. He thought it was also quite a move in the right 

 direction to provide a good coarse adjustment in place of a shak}'- 

 fine adjustment. 



Mr. E. M. Nelson said he had seen Messrs. Watson's new 

 eyepiece, but it was not exactly a compensating eyepiece in the 

 strict sense of the term, but was an ordinary Huyghenian 

 eyepiece, in which the distance of the lenses apart could be 

 adjusted, and it was open to doubt whether the ordinary micro- 

 scopist would not be more likely, in attempting to improve the 

 adjustment, to spoil it altogether. He thought it would be 

 better if it were marked ofi" for long tube and short tube 

 instruments ; the present markings were empirical, but it was an
