•which is readily and cheaply performed, would render the 

 most delicate carvings in this stone impervious to smoke, 

 and quite, if not more durable, than ordinary bandstone, 

 and at much less cost. 



The only uses to which this stone is applied are, the 

 moderately porous portions for water-filters, and the friable 

 parts for mixing with night-soil to be used as manure. 



A sample which has been exposed to the acid vapours of 

 the laboratory has in a year suffered but little.

 In former papers communicated to this Society I have 

 dwelt particularly on the vast numbers of white cells seen in 

 the blood after death from snake-poison. Subsequent and 

 repeated observation have confirmed my original description 

 equally of the growth, size, and maculated condition under 

 the influence of magenta of these bodies ; but lately my 

 friend Mr. Ralph, surgeon of Kew, near Melbourne, has 

 discovered a nearly similar condition of blood in animals 

 poisoned by prussic acid. I have confirmed his observations, 

 and most probably such bodies will be found and arise 

 wherever after death coagulation of fhp Klnnn 1 does not take
