made by SCHROEDER VAN DER Kork *) and by Srrusrorr ®). The latter 
and | probably came to make it unter the influence of what was 
told by Rormer*) with regard to the origin of this kind of erratic- 
blocks. With SCHROEDER vy. bp. Kork this is certainly the case, as 
appears from the note at the bottom of the page. 
As to their being found at Hardeberga in the neighbourhood of 
Lund, Rormer seems to have forgotten the fact that Toren. *), though 
he at first communicated that the Hardeberga sandstone contained 
worm-shaped bodies probably belonging to Seolithuslinearis Hail, 
afterwards makes mention of a new kind, viz. Scolithuserrans Tore *), 
The latter are distinguished for being mostly curbed and running 
through the stone in various directions. 
Rormer’s information that Tori describes Scolithuslinearis from 
an erratie-bloek found near Lund, and that according to Ninsson 
Scolithus-sandstone occurs near Calmar (as firm rock), must be attri- 
buted to an error. If my imperfect acquaintance with the Swedish 
language does not deceive me, Torri. *) writes that the place where 
the pictured stone (an erratic-block) was found, cannot be indicated 
for sure, but that Ninsson thinks he remembers that it was found 
near Calmar. 
In the Northern part of the Netherlands erratic-bloeks of Scolithus- 
sandstone are rather common. In Frisia were found, besides the 
stone treated of above, one in the Roode klif (Red Cliff) ”), one in 
the Mirnsercliff*) and one at Warns (see number 3). Among the 
erratic-blocks of the Gron. Hondsrug *®) only one piece was found up 
to this time, whereas I formerly deseribed already two pieces from 
Kloosterholt '°) and afterwards gathered more of them there. In the
