Beyschlag to the committee. It was decided that the report of the com- 
mittee should be presented to-day. M. Karpinsky proposes to name a 
committee to consider the principles necessary to the chronological 
classification of the sedimentary rocks. It is decided to name them at 
the next session. M. Gaudry presents the invitation of French geolo- 
gists to the Congress to meet in Paris in 1900. M. Heim thought the 
distractions of the world's fair in that year and place would hamper the 
work of the Congress. M. Emmons, in the name of some of his Amer- 
ican colleagues, offered the following resolution: "That in future the 
quality of member of the Congress be reserved for persons whose candi- 
dacy shall have been approved by the principal geological societies or 
institutions of the country to which they belong." On motion of M. 
Mendes Guerreiro the council decided to separate the questions of the 
place of meeting and the limitation of the admissions. M. Karpinsky 
put M. Gaudry's proposition to vote. M. Tietze states that the Aus- 
trian geologists have been charged with inviting the Congress to hold

the articles by MM. Bitner and Freeh modified and condensed by MM. 
Karpinsky and Tschernyschew. 
I. "The introduction of a new stratigraphical term should be based 
on well determined scientific need and occcasioned by peremptory rea- 
sons. Every new appellation should be accompanied by a clear bati'o- 
logical and paleontological characteristic of the deposits to which it is 
applied. At the same time it ought to be founded on the evidences not 
of a single section but over a more or less considerable space." MM. 
Renevier, Dep^ret, Mourlon, Grossouvre, and Tschernyschew debate the
