I don’t know why this works (or if it will work for everyone), but:
Once the Google Books review of pg 222 loads … if you use the arrows at above right to go backwards first to pg 219, and then use the arrow to go back forward … it will display both pg 222 and then pg 223 with all the Hittite text.
And when I access that pg 222 directly from Google (search terms were the title of the book, ‘Deutscher’, ‘Hittite’, and ‘conjunction’), it displayed pgs 222-223 just fine.
