sir i dun agree wid u.
i dun think that samo's book is full of mistakes.
of course there may be a few printing mistakes but i may tell u that itz really a very good book if u r a student of arts and hv nodding acquaintance wid this subject of EDS. i assure u that it has no match.itz portion of Biology is matchless.whereas kashmiri's book excels in physics.this is how it goes.
