Exhibits. — J. G. O. Tepper, F.L.S., a caterpillar fun- 

 gus from Davenport, England. This fungus (Spharia mili- 

 taris) is of a bright-scarlet colour and erect growth. It would 

 appear that, owing to the caterpillar burying itself in the soil 

 preparatory for its pupa state, the spores of the fungus 

 very readily find their way into the creature's body, which 

 becomes filled with the mycelium of the plant. Mr. W. 

 Howchin, F.G.S., exhibited a piece of barbed wire from a 

 fence at Blackfellows' Creek which had been struck by light- 

 ning. The lightning had run along the fence for 5 or 6 

 panels, fusing the surfaces of the wires and welding together 

 some of the barbs. Leaving the fence the charge struck a 

 tree about a chain away, splitting the butt and tearing up 

 the ground around. The President exhibited a fulgurite 

 or lightning-tube. The portion shown was 18 centimetres
