the tongue of ‘a dog produces instant death. Three ounces 
of the oxid of arsenic were afterwards given him, and: the 
same dose again repeated but without any effect... About 
an hour afterwards he was shot through the head. with a 
cannon ball and expired withouta struggle. | Notwithstand- 
ing the poison he had taken, three or four hundred individ 
uals ate of his flesh without inconvenience. . His skeleton 
was carefully preserved for the Museum of Natural History;

an artificial animal to be placed in the same: inclosure. .-The 
occurrence at Venice, and that just: described, very: properly 
suggest doubts of the propriety of suffering these animals to 
be'taken about the country without greater precaution, :da

61. Spirits in glass Jars closed with Bladder, mode of wm- 
proving wines.—Dr. Summering, in a curious set of experi- 
ments detailed in the Memoirs of the. Munich Academy of 
Sciences, has proved, that if mixtures of spirit of wine. and 
water in glass jars, are covered, some with bladder and, oth, 
ers with paper, that the aqueous ingredient escapes through 
the bladder, and leaves a concentrated. spirit ;, while on the 
contrary, it is the spiritous ingredient which, passes. through 
the paper, and leaves little else than water. . It is proposed 
to fine and improve wines by exposing them in vessels cov- 
ered with bladderor some similar substance. In some ex- 
periments made with Cyprus wine, a sixth part escaped, 
and the wine was very much improved in quality... This 
mode of improving wines is practised in some parts of Sua-
