poses in barrels from Briisa and Magnesia. Biit a white lime 
marl, abounding in shells, occurs between the Ida and Lassitei? 
mountain, and, in general, this island is covered with numerous 
soft, calcareous, and clayey substances of a white colour, hence 
the modern name Candia. — Skiers’ 1 Travels in Candia , vol. L

41. Electricity elicited from the Domestic Cat.— In ad- 
dition to the notice in the Philosophical Journal , of elicit- 
ing sensible shocks of electricity from the body of a cat, I 
beg to mention, that very distinct discharges may be obtained 
by touching the tips of the ears, after applying friction to the 
back. It is very long since I made the experiment, and, at the 
same time, I remarked the same from the foot. Placing the 
cat on my knee, I applied the right-hand to the back, the left 
fore-paw resting on the palm of my left-hand, I applied! the 
thumb to the upper side of the paw, so as to extend the claws, 
and by this means brought my fore-finger into contact with one 
of the bones of the leg, where it joins the paw ; from the kilob 
or end of this bone, the finger slightly pressing on it, I felt dis- 
tinctly successive shocks, similar to what were obtained from the 
ears. It is perhaps unnecessary to say, that in order to this ex- 
periment being conveniently performed, the cat must have been 
from an early period on good terms with the experimenter. 
42. Mammifera of Scandinavia.— hi . Nilsson published at 
Lund, in 1820, a work on the Mammifera of Scandinavia-, 
in which he describes 74 species, and which he has enriched 
with observations on the principal anatomical differences pecu- 
liar to each species. He has not neglected to mention the bones 
which occur in the peat-bogs of Scania, some of which belong 
to animals of more southern countries, as the wild boar, the bi- 
son, urus, bear, &c. ; while others, such as the elk, the rein-deer, 
and beaver, are only found now in the northern parts of Sweden. 
43. Swedish Ornithology . — M. Nilsson, who had already 
written some papers on the Birds of Sweden, in the Memoirs 
of the Stockholm Academy, for the years 1816 and 1817, par- 
ticularly in what concerns the synonymy, has published at Co- 
penhagen, in 1820 and 1821, the two parts of his Ornithologia
