A letter from J. Francis Williams was read by the Secre- 

 tary, announcing the discovery of a new mineral monticellite, 

 containing perhaps some alumina as a replacement of the iron. 

 The foci are given as aP, aPa, aPs, Pcx, P Pa. The a Pot 

 is extremely large as compared with most species of monticel- 

 lite, and gives the crystals the appearance of being of equal di- 

 mensions in all directions at right angles to the vertical axis. 

 It is also columnar, and the fundamental prism aP is more 

 decidedly developed than the aPT foci. The crystals have some- 

 what the appearance of monazite crystals, with this exception.
