On the falling and rising* of Lake Venner.
Swedexborg’s manuscript88 on Lake Venner1 has, as is known, been
made the subject of a critical examination by Professor R. Sieoer of
Vienna (now in Graz) to whose more extended account those who are
interested are referred1 2. The matter to be explained was the faet that Lake
Venner from time to time rises (or falls) even as much as 0.6—1.8 m. above
(or below) its usual niveau. Swedenborg calculated at Rånnnm’s Bridge
the quantity of water which leaves the Lake through Göta Elf, and in
doing this he came to the conclusion, that the quantity was so
inconsi-derable in comparison with that of the Lake itself, that if the outlet
were closed up for a wThole year, the rising of Lake Venner caused by
it would amount to only O.is m. If on the other hand the inliow were
supposed to be shut off for the same length of time, the sinking of
the Lake’s surface would not pass beyond the same point, for according

2 R. Sieger: Eine hvdrographische Studie Swedenborg’s. Nachrichten uber
Geophysik. Bd. I. Wien, 1891. Sieger, who had access to a photolithograpliic facsimile
of the original manuscript by Swedexborg which is preserved in Linköping, has not
indeed been able to decipher every word and has therefore made one or two mistakes,
hut these are of subsidiary significance and have little influence on his work as a
whole. I shall here point out that which has caused him the greatest trouble.
Swe-dexborg, in the first section of his paper, gives as an exainple of the changes in the
height of the water the following: »Strandbonden theromkring wet at berätta, huru
han ibland förlorar sin åker och eng; ibland får han stora ypna trader, i thet at
jord-mohnen sluttar longsamt», etc. (»The farmer near the shore at that place relätes that
he has sometimes lost his arable lands and meadows; sometimes he receives large
open tracts, because the surface of the ground slopes graduallv», etc.) Sieger here read:
»ibland får han stora yxan», and although he thought that the indistinct word following
»yxan» really was »tracter», he believed that for the sake of the connection it should
be interpreted as being »kasta», that is, the meaning should be: »sometimes he may
throw the great axe», (»ibland får han stora yxan kasta»), which would mean that the
farmer at the shore might sometimes win as much land as corresponded to the throw
of an axe. The erroneous interpretation therefore followed from this, that Sieger
read »axe» (»yxa») instead of »open» (»ypna»).
In the first portion of § G Sieger has read »vanliga» (»usual») instead of »longliga»
(»long») and therefore translated it with »gewöhnlich», and in the last portion of
page 123 of the facsimile of the same section he has read »snart» (»soon») instead of
»swTårt» (»difficult»).
