To satisíy our readers as to our design in sending 
tliem tliese «Notas Preliminares» is also to set fortli 
our airn in publishing tliem. We purposely avoid giving 
tliese the naine of «periodical»; for one of tlie reasons 
that led us to starting tliem, was exactly the fact of 
our being freed from any obligation of publishing tliese 
papers at any fixed time; nor could we risk doing so 
in view of the many scientific as also administrative 
duties which fali on the Director and his only assis¬ 
ta nt. 
Nevertheless the Revista do Museu Paulista will 
continue to be the principal organ which organ, we 
may be allowed to say, lias found the best reception on 
the part of the scientific world to which it is addres- 
sed and destined. That it is so, is proved by the large 
number of congenious publications we have received by 
way of interchanging what may be surely a good 
reason to fill the zealous founder with just pride. But 
for the difficulties already mentioned above and for 
others of a purely technical character, it was impossible 
to make the Revista appear in shorter periods wliere- 
fore we resolved to edit these «Notas Preliminares», 
the numbers of which will be published according as 
the scientific works when finished require it, The single 
fascicles, will, therefore, not be subjected to any limitation 
and as to illustrations, they are wanting therein as they 
clieck a rapid printing.
