Through exchange and purchase our collection of meteor- 

 ites has received several noteworthy additions : a 2,145-gram 

 (5 pound 6 ounce) mass, the largest known of the Cumber-

 a 467-gram (1 pound) cut and polished fragment of the same 

 fall; an 8,320-gram (18 pound 5.5 ounce) entire mass of the 

 Richardton, North Dakota, aerolite which was seen to fall 21

 etched portion of a new iron meteorite from Australia; an 

 entire new iron meteorite weighing 57,833 grams ( 127 pounds

 aggregating 766 grams (1 pound 11 ounces) of the El Perdido
