conclusion but to the one, that Hydrocarbons can occur not only there: 
where we may touch their mother-rock, the Schlier, with our hands ; they: 
are bound to occur also there, where the Schlier is covered by younger 
deposits. (These occurrences must be considered to be the more promi- 
sing ones.) On the other hand wherever there are Hydrocarbons or 
products of their transformation, the mother-rock must also be present. 
I hope dr. Lóczy will not deny, that the mother-rock of the 
Hydrocarbons is always some salt-formation, and I am sure that he. 
does not know any other mother-rock in Central-Europe but the: 
Mediterranean Schlier — as none of our experts does know any " 
other. 
If he acknowledges this, he must realize, that even in the Lower 
Mediterranean only a very small part of the Hungaro-Croatian Basin 
could have been dry land, where the mother-rock for the Hydrocarbons. 
would not have deposited, and that conseguently we must on hand: 
of general tectonical and geological knowledge expect to find them 
not only on the territories superficially named by me, but generally 
on the territory of the whole Hungaro-Croatian Basin. 
That dr. Lóczy did not take these into consideration may easily" 
be understood since he, by now, had very little to deal with the geological : 
conditions of our Tertiary Basin and so he is not correspondent with 
the results of our research made since a series of years. 
Under the éiven tacts it is only natural that one can not speak 
seriously of an Oriental Dry Land in the. center of the Hungaro- 
Croatian Basin as dr. Lóczy thinks it in his fancy on the authority" 
of Messrs Peters, Mojsisovits and his late father. The mountains 
which were on the surface have broken and sunk down rather long" 
before the Mediterranean and it was only their remnants which pierced 
out — principally in the form ol the actual Island Mountains —, 
else we could not know occurrences of Schlier in such broad a, circle, . 
nor the Hydrocarbons indicating its presence. 
Dr. Lóezy is wrongly informed also with regard to the Island-. 
Mountains: he totally neglects their primary tectonical conditions, . 
the folding, for the sake of their secondary broken structure — whereas, 
would he take into consideration, his fathers Paper on the Balaton 
and his numerous profiles, he ought to see, that the Northern part 
of the Balaton consists of a series of brachyanticlines and brachysin- 
clines in the same way as the Pécs Mountains, as shown by the maps.

On hand of the descriptions and profiles by Mr. Lóczy senior,.. 
domes must be established near Almádi, Hidegkút and Révfülöp on a 
Palaeozoic core in Mezozoic deposits, but it can be seen that also the-
