Hi,
I've read about the BJT in the following page:
http://www.allaboutcircuits.com/vol_3/chpt_4/1.html
I think that the electrical current flow direction is inverted.
The same thing occurs in other paragraphs of this chapter.
That's why I think it's weird - because that there's no chance that the same mistake keeps appearing in your book.
On the other hand, according to what I've learned, the content in the above quote is incorrect.
In the NPN BJT, the current goes from base to the emitter.
In the PNP BJT, the current goes from the emitter to base.
Thanks,
Dor.

It says that in a PNP transistor, the electrical current goes from the base to the emitter ; the same mistake happens with NPN (electrical current goes from emitter to base).The small current that controls the main current goes from base to emitter, or from emitter to base, once again depending on the type of transistor it is (PNP or NPN, respectively).
