366 Analyses of Boohs. [June, 
Records of the Geological Survey of India . Vol. XIV., Pert 2. 
1881. 
We find here notes of Mr. R. Lydekker, F.Z.S., on certain 
Gondwana Vertebrates. There is mention of the mandible of a 
labyrinthodont differing from any known European or American 
fossils hitherto known ; the skull of Gonioglyptus longirostris, a 
crocodilian from the Rewah Rocks ; a Hyperodapedon from 
Rewah, indicating a much larger animal than any hitherto known, 
and probably about 16 feet long. The same author communi- 
cates a paper on the ossiferous beds of Hundes, in Tibet, in which 
it appears that all the extindt Siwalik forms are absent. There 
are indications that the climate of Tibet must have been at one 
time much milder and moister than at present. Cunningham 
has shown that shells, now found living at heights not exceeding 
11,000 feet, are found fossilised at 15,000. 
In some notes on the Mining Records we find that the total 
yearly output of coal in India is at present only 1,000,000 tons. 
The writer, Mr. T. W. H. Hughes, F.G.S., comments on the 
exclusion of women and girls from underground employment in 
English mines, which if extended to India would wofully reduce 
the available labour. He adds, “ Until education and civilisation 
have penetrated more deeply into the mind and system of our 
female Bauria and Sontal colliers, we may defer placing them on 
the same platform as the British miner’s wife and daughter.” 
Mr. Medlicott adds, very appositely, “ or perhaps until the vices 
of { civilisation ’ have degraded the male element of these simple 
people to the moral level of a large part of the British mining 
population.” 
Mr. Mallet, F.G.S., communicates an interesting paper on the 
Cobaltite and Danaite of the Khetri mines of Rajputana, first 
discovered by Mr. J 9 Middleton, F.G.S. The cobaltite in question 
is remarkable for its purity, and contains 64‘64 per cent of cobalt. 
It is used by Indian jewellers for imparting a delicate rose-colour 
to gold, but the process they employ is guarded as a secret. It 
is remarked that mineralogical text-books disagree on the be- 
haviour of cobaltite in the closed tube. The author finds that, 
whils mispickel gives a sublimate at a moderate red-heat, co- 
baltite and glaucodot remain unaltered until the temperature at 
which glass softens. 
Vol. XIV., Part 3. 1881. 
In this issue we find an important paper by Mr. H. B. Medlicott 
on Artesian Borings in India. The want of water being so fre- 
quent and disastrous, it is only natural that the attention of the 
Geological Survey has been turned to these wells as a possible 
remedy. At the French settlement of Pondicherry an excellent 
supply has been obtained. In other parts they have either proved
