Notice of the Address of T. Sterry Hunt. 87 
incipient to complete alteration, in the latter case not a trace of 
the original mineral remaining. 
In his assumption, for it is little better, he opposes the views 
of every writer on pseudomorphs, excepting one—Scheerer ; 
and Scheerer’s chemical speculations, which are at the basis of 
his opinions, he rejects, like all other chemists. 
is unwarranted assumption has a profound position in the 
system of views on metamorphism which Professor Hunt holds, 
ok gives shape and intensity to his opinions of the views of 
others. 
. That, in commencing a paragraph with the sentence, “ The 
doctrine of pseudomorphism by alteration, as taught by Gustaf 
Rose, Haidinger, Blum, Volger, Rammelsberg, Dana, Bischof, 
and many others [meaning thereby other writers on pseudo- 
mmelsberg, Dana; and that he completes the caricature in 
the closing sentence of the same paragraph, in which he says, 
“In this way we are led from gneiss or granite to limestone, 
from limestone to dolomite, and from dolomite to serpentine, or 
more directly from granite, granulite or diorite to serpentine at 
once, without passing through the intermediate stages of lime- 
Stone and dolomite ;”—part of which transformations, I, for 
one, had never conceived; and Rose, Haidinger, Rammelsberg 
and probably Blum and the “many others,” would repudiate 
em as strongly as myself. Next follows a verse from Goethe, 
that is made to announce his personal vexation with their 
“ sophistries ;” alias absurdities, as the context me 
Professor Hunt's rejection of established truth alluded to 
under §1, here manifests its effects in leading him to misrepre- 
sent—although, unintentionally—the views of writers on pseu- 
access to great beds of rock. Haidinger, the eminent crystallo- 
most prominent writers on pseudomorphism, never wrote upon 
the subject of the alteration of rocks at all, and this is true of 
others against whom the above charge is made by Mr. Hunt. 
With a little clearer judgment, part at least of that vexation of 
spirit, which required the help of a great German poet, and the
