The two heaviest gold nuggets found in Victoria from Oaober, 
1877, to June 30th, 1879, weighed respectively 20 lbs. 10 ozs. 
and 23 lbs. 6 ozs. troy. 
Psilomelane containing from i to 7 percent of cobalt is ob- 
tained in many localities in Victoria, and is profitably worked by 
a process devised by Mr. Malcolm Hills (“ Geological Survey, 
Vidto:ia,” vi.). 
According to the Rev. G. K. Morris (“ American Naturalist ”) 
Pheidole pennsylvanica , an ant found in New Jersey, is a true 
harvester. 
Mr. E. J. Hill, writing in the same journal, describes a non- 
poisonous snake which very successfully mimics the rattlesnake. 
A honey-colledting ant with an enormously distended abdomen 
has been discovered in Australia. 
M. Adalere Lienard has communicated to the Academy of 
Sciences of Belgium a memoir on the nervous system of the 
Arthropoda and the constitution of the oesophagian ring, in 
which he recognises four distinct types : — that of the Crusta- 
ceans * that of the Dytisci, common to a great number of carni- 
vorous inseas ; that of Cossus ligniperda , which occurs in the 
larvae of many moths, locusts, and herbivorous or ligmvorous 
beetles ; and finally that of the suaorial inseas. (It is strange 
to find the brain of Necrophorus vestigator and N . germamcus 
belonging to the first of these types, whilst the kindred form, 
Silpha nigrita , is assigned to the third.— Ed. J. S.) 
According to the “ Geological Magazine " an entirely new 
fauna has been deteaed, in the Menevian States of St. David s 
and of Dolgelly, which were considered wholly unfossiliferous. 
The fossils were discovered by looking at the bedding-ends ot a 
number of the slates placed together in their natural position.
