perfect, and the young fry, samlets or smolts (smouts) make 
their appearance in March or April. When the samlets leave 
the gravel, where the spawn from which they issued had been 
deposited, they begin to move downwards to the seat^^i; In their 
progress through the river, and until they reach that point 
where the frith begins, (or where the tide is always either eb- 
bing or flowing,) they crowd together, and descend in the easy 
water at the margin. But, upon entering the frith, where ibe 
easy water is not at the edge, they betake themselves to the deep- 
est part of the channel, and, along with the kelts, disappear from 
observation. — Rev. Dr Fleming. 
29 . Determination of' the question relative to the origin cf' the 
domestic Dog. — M. Desmoulins, considering, with Pallas, that 
the wild stock of all our old herbivorous animals still exists, 
notwithstanding the weakness of their means of defence and of 
preservation, as well as their limitation in respect to number, 
which bears no proportion to the multiplication of the species of 
the dog genus, and notwithstanding their various confinements to^ 
several islands, the Mouflon to Corsica, the (Egargus to Sardi-'^ 
nia and Crete, &c. ; has proved that the ox kind is not an ex- 
ception, since it still existed in Poland not three centuries ago ; ^ 
that the domestic dogs again become wild, could not be destroyed, ^ 
and that a species which has not yet been reduced to subjection, 
still possesses means of maintaining itself in a state of indepen- 
dence ; that no historical testimony gives evidence of the extermi- 
nation in any extensive country of any wild animal analogous to 
the dog ; that all the presently existing species of this genus are 
mentioned by ancient authors in the countries with which they 
were acquainted ; that there existed dogs in both Americas be- 
fore the arrival of Columbus ; that, accordingito Peter Martyr 
and Oviedo, there existed both in the Antilles'and on the main- 
land, dogs of every description and colour ; that the domestic 
dogs of the Antilles were not indigenous, and had been import- 
ed from the Continent ; for in the time of Oviedo, who had seen 
them in great numbers on the Continent, they no longer existed 
in St Domingo, where, in a famine, during Columbus’s second 
voyage, they had been destroyed to feed the population ; that 
the Caribs, at this period, having the preponderant power of the 
east of the continent and of all the islands, must have introdu-
