phism has recrystallized any first formed porphyritic matter. The 
metamorphism of igneous or intrusive rocks is a subject now attract- 
ing much attention, and has important bearing on the origin of the 
Archean.' As for explaining the slight bedding or laminations 
of the wall rocks by previous sedimentary stratification, while it is 
not easy to adduce any positive facts against it, the writer does 
not believe in it. It seems most reasonable to regard the 
laminations as due to pressure exerted normally to them, and 
that the pressure was in almost all cases normal to the dikes as 
well. 
The origin of these well-nigh massive basal rocks of the Archean 
is certainly at present a most uncertain theme. Yet, although it is 
readily to be seen from much that has been written how easy it is to 
indulge in laboratory speculations which afford little else than contro- 
versial material, the writer would nevertheless advance the conclu- 
sions drawn from the structure and composition of these dikes as 
legitimate if not incontrovertible inferences. 
SCIENCE IN UTOPIA.

I has doubtless been a matter of regret to many of my r readers 
that since the publication of the valuable memoirs of Sir Thomas 
Moore upon Utopia no one has succeeded in penetrating the veil of 
mystery hanging over those happy islands. 
For my own part I have often amused myself by wondering 
whether egress is as difficult as access and in imagining a sort of 
espionage of modern institutions by that conservative and self- 
satisfied community. 
Very unexpectedly my vagaries were suddenly proven realities 
and I am permitted to record the results of an extended conversation 
with a representative and very intelligent member of the 
scientific congress of Utopia.
