ARSENICAL COMPOSITION. 
Mr Laurené’s Receipt. 
A distinguished French naturalist, Laurent, recommends | 
the following composition, after ten years’ experience, for pre- 
serving the skins of stuffed animals. He observes, at the same 
time, that it penetrates them with greater readiness, and pre- | 
serves them much better than any preparation which has | 
hitherto been in use.

wine to be poured on them, at a heat of twenty-five degrees, 
and they will be perfectly combined in twenty-four hours. |

| The essence of thyme is then added, when the phial must be |
