 enabled to secure the copy of Dr. Hauswaldt's valuable work for the 

 library of the Society. 



Mr. T. H. Powell exhibited in the room a new apochromatic homo- 

 geneous-immersion ^y in. objective which was slightly different in 

 construction from those he had previously made, but which he con- 

 sidered was the best he had yet produced. 



Mr. C. L. Curties (C. Baker) also exhibited a T ^ in. achromatic 

 objective made on a new formula, which gave a very flat field and had 

 an aperture of 1*30.
