I have put up an online photo gallery with readable pictures of several chapters.  Here is the link, which opens in a new window:

This book has been very useful to me in my studies of alchemy.  Amongst the revelations are that:

1.  All the alchemical formulas were striving to make silver and gold in liquid form.

2.  Most of the recipes didn't have silver and gold in them, though some did.

3.  The Golden Liquid is a very documented textual and practical tradition in early Daoism.

4.  The use of gold and silver waters are considered far higher than any plant based herbs and exercises, but must be combined with meditation for full effects.

5.  External Alchemy still has an important role in the Daoist Canon (Dao Zang), but became replaced by internal alchemy teachings which used the symbolism of refining metals to assist internal visualizations in meditation.
