Morphling-san, Toritoribe-san...........you two are excellent; this makes me want to get into a more regular (read: at all) habit of brushing up on my Japanese. That's all I wanted to say.
It might be the most authoritative book for non Japanese speakers like yourself but nobody in Japan cares. It's an English book for cry out loud.
I have already pointed out the mistake which is a limitation on the authors English (they are Japanese after all) and an errata that needs to be corrected. To say 自使 is the same as 他動 only makes an *** out of yourself as both toritoribe san and myself have proven time and time again.
You deleted the link to a copy of a page of the textbook, but I can point out where the textbook is mistaken (for instance, although the textbook gives an example 食べさす, why it's considered wrong as Modern Japanese).
