Prof Milne — Across Europe and Asia. 
given to me by Miss Catbleen Campbell, now Mrs. Szlenker, who 
bad been keeping a record of meteorological and other phenomena. 
The sbock took place at 2 '55 a.m. on the 4th September. It was at 
first feit in a direction from east to west, but after lf minutes it 
changed to N.E. and S.W. The shock, which was severe, caused 
Ornaments on the table to rattle, and a few bottles which were close 
together knocked each other with so much force that tliey feil over. 
There were thirteen of them, and they tumbled in various directions 
— nine feil on the table, and four were broken on the floor. Watches 
and clocks were stopped, and screws 1J in. long, fastened in the 
wall to keep a clock straight, were drawn out. Preceding this shock, 
from observations which I saw, the barometer appears to have been 
lower than usual. 
From a list of earthquakes drawn up by MM. Orlof and Stuikin 
as having occurred between the years 1725 and 1874, there appear 
to have been at least 188 different days on which shocks were dis- 
tinctly feit. As these were all perceptible to the inhabitants, and 
not such as needed delicate instruments in order that they should Vfe 
recorded, we cannot well make comparisons as to their frequency, 
but only as to their relative intensity. 
The severest of these happened at the end of the year 1861. The 
district where the effects were most observed was near Irkutsk and 
along the shores of Lake Baikal. On the N.E. portion of the delta 
formed by the River Selinga where it enters the Baikal, the effects 
were permanent. This district, which was violently disturbed, is 
about forty versts long and 20 versts wide, and runs along the shores 
of the lake. On this strip of land were situated the Russian villages 
of Kudara, Doobeeneena, Oimoorchi, and a Bourat viUage, with a 
population amounting in all to 1300. 
The first shocks, which were light, took place on the 29th 
of December. Next morning they were stronger, and on the 
succeeding night, that is, between the 30th and 31st, they not only 
increased in number, but their power also increased. On the after- 
noon of the 31st, at 3 p.m., a heavy Underground rumbling was 
heard, and this was followed by a series of shocks so strong that 
it was impossible for persons to remain standing. Barrels in a yard, 
each containing twenty pouds (720 lbs.) weight of fish, were rolled 
backwards and forwards from one end of the yard to the other. In 
the yard and in the Street the earth was cracked, and water charged 
with mud issued from the crevices thus formed. In some of the 
wells water rose like a “ fountain ” a fathom or more in height. 
Some of the fissures formed springs of clear fresh water, one of 
which, issuing from a crack about one arsheen (28 inches) wide, and 
two fathoms (12 feet) deep, gave so much water that a small lake 
was formed a verst in area. In the village of Krasnikova a hollow 
place twenty fathoms wide and three fathoms (18 feet) deep, with a 
spring in it, was formed. 
In a church at the village of Kudara, the shocks were so strong 
that the cupola feil down inside, breaking a chandelier which was 
hanging beneath. In the houses at the same village so much
