July, 1914. New Meteorites — Farrington. 13 



3 grams. The classification was given as mesosiderite or pallasite, 

 each with an interrogation mark, and the date of find as 1857. It was 

 queried also by Wulfing whether this find should be united with Cowra. 

 With the purchase of the Gregory collection by the late Prof. H. A. Ward 

 the 58 gram specimen passed to Ward* who listed it as a mesosiderite 

 and gave the locality as latitude 31 30' S. and longitude 152 56' E. 

 Meunierf classed Macquaire River as logronite and described it as 

 follows: "We have only a small piece of this meteorite; but in spite of 

 its weight, which does not exceed 1 gr., there is sufficient for exact 

 determination and without hesitation we include it among the type 

 logronite." In the catalogue of the Berlin collection by Klein, in 1906,! 

 13.5 grams of Macquaire River were listed and classed (p. 13) as a meso- 

 siderite. Klein also (p. 103) gave the following description: "Shows 

 megascopically much iron but finely distributed. In this section the 

 silicates appear much decomposed, but a little chrysolite is clearly seen." 

 Anderson § listed Macquaire River among the Australian meteorites 

 and its possessors as Ward-Coonley and the Berlin Museum. The above 

 seems to be all the information that has h'therto been published regard- 

 ing this supposed meteorite. 



On the acquisition of the Ward-Coonley Collection by the Museum, 

 the 58 gram specimen came to the attention of the writer and as some 

 of its characters seemed unsatisfactory from the meteoric standpoint, 

 it was given further study. The specimen is a fragment thinner than 

 broad, having a polished surface of about 12 sq. cm. The unpolished 

 surface is of iron-black color, the polished, nickel-white to bronze. The 

 luster throughout is metallic and the mass is magnetic. The unpolished 

 surface is rough without being jagged, but is especially marked by sev- 

 eral pits, two of which are of elongated form while the others are circular. 

 The diameter of the circular pits is about 2 mm. while the elongated 

 pits are from 10 to 15 mm. long. These pits are too regular in form and 

 have edges too sharp to correspond to the usual type of surface pittings 

 on meteorites. The polished surface appears to the naked eye to be of 

 nearly uniform color and luster, but with the lens shows numberless dots 

 of a bright gray metal imbedded in a dull-black ground mass. The 

 form of the individual dots is in general circular but they are usually 

 grouped into elongated forms so that something of a pattern is given to 

 the surface. The appearance of a mesosiderite is thus somewhat simu- 

 lated, but the metallic dotting is more uniform and abundant than the
