HARDWICKE'S SCIENCE-GOSSIP. 



A. W. Ogilvie. — "Asbestos" is the name given to the 

 fibrous varieties both of hornblende and pyroxene, chiefly of 

 the former. Pumice-stone has nothing to do with it, being a 

 light felspathic cellular substance, ejected from volcanoes. 



F. W. Crick. —Your glass tube was quite smashed when it 

 reached us, but we were able to secure as much of the specimen 

 as caused us to believe it is one of the leech family, most 

 probably Clcpslne hyalina. Try and send us a live specimen.
