at the places named in Wyrley liberty. The Wyrley Bank 

 Colliery has been opened, worked by royalty, and raising 10,000 

 ton of coals annually, employs about thirty families. Attached, 

 is a manufactory employing about fifty workmen. The coals 

 are conveyed on a rail-way, a considerable distance, to the turn- 

 pike road for sale and use. The manufactory consists of augers, 

 and edge and plantation tools, which are now in full work, notwith- 

 standing the depression of the times. The screw auger, a modern 

 tool, is made in great perfection ; it enters and perforates the 

 hardest wood with facility without any preparation. A steam- 

 mill is in full work at Church Bridge, in the manufactory ; and a 

 water-mill on the Hedgford river, called Wedges Mill, is also at- 

 tached to it, and the whole appears a thriving concern, established 

 within about the last twenty years. 



Addition to the Natural History of Insects* The following, 

 though apparently whimsical, is from high authority. Dr. Hirsch, 

 dentist at the court of Vienna says, the lady-bird (Coccinella sep- 

 tern punctata) will cure the tooth-ache, thus : take the living in- 

 sect, and bruise it between the fingers, then rub these fhige^s till 

 they become warm at the points, and touch with them the unsound 

 part of the gum, also the diseased tooth; this he did with the hap- 

 piest effect. A few days after he repeated the experim. nt with 

 equal success, without bruising a new insect. The following insects 

 have, it is said, the same virtue, used in the same way : the poplar 

 beetle (Chrysomela populi) length half an inch, on poplar trees ; 

 the wood beetle (Chrysomela sanguinolenta) wings rod, length 

 five lines, under side blue, shells black with a red border ; found 

 in woods ; also the curculio and carabus species, found on various 

 plants. Charcoal is also recommended, from high authority, as a 

 preyentative and cure of the same complaint. 



Conformably to an ancient custom of the Manor of Newcastle- 

 nnder-Lyme, within the Duchy of Lancaster, it is essential that the 

 original wills of copyhold tenants, dying seised of copyholds, should 

 be produced and proved in the Manor court, within a limited time 

 after the decease of the testator, or testatrix, in default of which 

 the estate is liable to forfeiture.
