NUMMULITES IN JAVA. 

 Sib, — In the Geol. Mag., No. 102, p. 561, Herr Verbeek is quoted 

 ns expressing a belief that the Nummnlitic Formation would probably 

 be found in Java and in most of the islands of the Indian Archi- 

 pelago, as well as in Borneo, where he found both known and new 

 species of Nummulina and Orbitoides. In a flint implement from 

 Java I have lately seen several small Nummulmce, probably the 

 same as N. Pengaronensis, Verbeek ; thus realizing Herr Verbeek's 

 expectation. T. K. J. 



THE DIVINING-EOD. 



Sir, — May I add to what has already been said coucerning the 

 divining-rod, that belief in its powers is not confined in Cornwall 

 to the ordinary miner. Men whose scientific merits are generally 

 acknowledged have in some cases more than a bias in its favour. I 

 found it the other day in use in the North of Devon, for the purpose 

 of tracing iron lodes. According to Pryce — " Mineralogia Cornu- 

 biensis" — it was first introduced into Cornwall by Cooksworthy, the 

 founder of the China clay trade, who learnt its use from a Spaniard, 

 then in command of the garrison at Plymouth, named Eiviera.

GEOLOGISING ON THE COTTSWOLDS. 

 Sir, — During the last two years I have been supplied by quarry 

 men with fossils from two quarries worked in the upper beds of the 

 Great Oolite, and the finds have been so numerous and remarkable 

 that I thought Geologists generally, and especially those located on 

 the Oolites, would like to know the results. I only propose to give 

 a general description of the fossils, some of which appear to be 

 new, especially the corals, very few of which have been drawn or 

 described. The quarries are located near Cirencester, and contain 

 similar beds of Oolite, and are severally 400 to 450 feet above the 

 sea. In one is a considerable fault, and in both, at times, is brought 

 to light a close vertical fissure, the faces of which are scored hori- 

 zontally. Denudation has carried away 12 beds of rock, together 

 28 feet in thickness, an<l the uppermost bed must be that on which
