No TIDES. It wants tides, therefore experiences no difference of height, except when the 
winds are violent. At fuch times there is a current in and out of the Baltic, ac- 
cording to the points they blow from ; which forces the water through the Sound 
with the velocity of two or three Danifh miles in the hour. When the wind blows 
violently from the German fea, the water rifes in the feveral Ba/tic harbours, and 
Nor sat. gives thofe in the weftern part a temporary faltnefs: otherwife the Baltic lofes 
that other property of a fea, by reafon of the want of tide, and the quantity of 
vaft rivers it receives, which fweeten it fo much as to render it, in many places, 
fit for domeftic ufes. In all the Baltic, Linneus enumerates but three fuci*, plants 
of the fea: in the gulph of Bothnia, which is beyond the reach of falt water, not 
one F. 
Few spECIES OF The fewnefs of fpecies of fifh in the Baltic is another difference between it and 
SUCHE a genuine fea. I can enumerate only nineteen } which are found in this vaft ex- 
' tent of water: and may add one cetaceous fifh, the Porpefle. No others venture 
beyond the narrow ftreights which divide the Baltic from the Kattegatte; yet the 
great Swedifh Faunif? reckons eighty-feven belonging to his country, which is 
wafhed only by thofe two waters. Let me mention the Herring as a fpecies which 
has from very early times enriched the neighboring cities. —TThere was, between the 
years 1169 and 1203, a vaft refort of Chri/tian fhips to fith off the ifle of Rugen, 
the feat of the antient Rugit, infomuch that the Danes cloathed themfelves with 
fcarlet and purple, and fine linen. 
The Hornfimpa, or Cortus Quapricornis, Faun. Suec. N° 321, and the 
SyncnaTuHus Typu_e, or Blind Pipe-fifh, N° 377, are unknown in the Briti/h 
feas : the firft feems peculiar to the gulph of Bothnia, and is a fith of fingular 
figure, with four flat hornlike proceffes on the head |. 
LENGTH AND The extent of the Baltic in length is very great. From Helfingor, where it 
Sepa THE properly begins, to Cron/tadt, at the end of the gulph of Fin/and, is eight hundred 
; and ten Englifh fea miles. Its breadth, between Saltwic, in Smaland, and the oppo- 
or THE Gutpuor fite fhore, two hundred and thirty-feven. The gulph of Bothnia, which runs due 
Borunta. north, forms an extent almoft equal to the firft, being, from Tornea in Lapland, to 
* Flora Suec. + Flora Lapp.
