The South Wales Institute of Mining Engineers have recently 

 held their annual meeting, under the presidency of Mr. Alexander 

 Bassett, of Cardiff. At this meeting, Mr. Greenwell communicated a 

 paper on " The Copper Sands of Cheshire," and " The Alderley- 

 Edge Copper Mines." Mr. Mather had a detailed description of 

 " The Machinery used in Boring Artesian Wells." The President 

 read a paper on " The Port of Cardiff, and the Aberdare Coal Fields. 

 Besides those, were communications " On Utilizing Pit Tips," by Mr. 

 W. Monks ; " On the Nature and Manufacture of Patent Store 

 Bricks;" and "On Re-Utilization of Slag from Blast Furnaces." 

 Nothing can be more satisfactory than the progress made by this 

 Institute. 



We regret to record the death of the Glasgow Mining School. 

 With every desire manifested on the part of the working miners 

 to avail themselves of the information to be 'obtained in this 

 school, it was found impossible to raise the necessary funds for its 

 support amongst the wealthy coal owners of Scotland. This indicates 

 a strange blindness to their own best interests ; but it prevails in 

 other mining districts than Glasgow. 



Mr. Low writes us : — " With respect to the working of my patent 

 boring machine " (described by him in detail, page 583, Vol. I. of this 

 Journal), " it has worked most satisfactorily, together with the new air 

 machinery, which I have constructed for working the same underground. 

 Although the machine I have made works very well (in which provision 

 was made for the tool to propel at three or four different speeds), yet I 

 found a slight alteration needful, inasmuch as the progressive motion 

 is so very varied. The alterations I am now effecting will perfect the 

 machine, and where the three following important features will be ob- 

 tained : — 1st. That the tool will progress as it cuts just in proportion 

 to the nature of the rock. 2ndly. The necessary gear and screw for 

 propelling the tool will be done away with, and the tool will progress 

 by the same agent as works the machine, and which will prevent the 

 tool and piston from crystallizing (caused by the very rapid percussive 

 blows), which affects the necessary gear and screw seriously. 3rdly. 

 There is also a cushion of air to receive the back blows, which will 

 also prevent the crystallizing of the working parts." 



Mineralogy. 



At a recent meeting of the German Association of Naturalists, 

 M. Rose read a paper on " Meteorolites." He divided those con- 

 taining iron into three classes — meteoric irons, pallasites, and meso- 

 siderites. He proposed, also, a division of meteoric stones into 

 seven classes — chondrites, hawardites, chassignites, chladnites, shalkites, 

 charbonites, and eukrites. A new mineral, discovered in a crystal by 

 M. Rose, in a meteoric iron, was described, to which the name of 

 rhabdite was given. Numerous papers, of more or less interest, were 

 read ; amongst others, one on " The Composition of Felspars," by
