Meteorites.— Very recently the name giovanite has been pro- 
posed by Meunier’ for a brecciated? meteoric stone which fell at 
intosh the following figures: : 
Olivine: SiO, = 37.90; MgO = 41.65; FeO = 19.66; MnO,CoO = 0.42. 
Iron: Fe = 82.45; Ni = 16.40; Co = 1.09; P= 0.05. 
Luis Potosi, Mexico, in 1885. It weighs ninety-two pounds. Its 
composition (analysis by Mackintosh) is: Fe = Ni,Co 
9.07; P=0.24; schreibersite=0.60. It resembles in character 
the irons of Augusta County, ’Va., of Glorieta+ Mountain, and 
others of the class caillite (Meunier). In a cylindrical cavity in 
this meteor can still be seen the broken end of a copper chisel.
