tinfoil " over the paint, then another layer of bladder well stretched 

 over, and cutting off the surplus neatly ; when dry, another couple 

 of coats of white paint, and the job is finished. This will keep the 

 specimens all right for a long time. H. W. Lett.

 from Germany, has been manufactured in Ireland from the top 

 layers of peat bogs. It is just the ordinary Sphagnum or Bog-moss 

 in a partially decayed state, and is largely used in a few places 

 for stable litter. H. W. Lett.

 have slides or material " named " through our Journal ? Valuable 

 finds are often neglected, and lost or put to little use on account

 to you in April last concerning the " circles," and which our
