ost opportune.... He avoids
unnecessary details, but includes everything that is essential to
systematic treatment, while he attempts no more 'than to give an
outline of the principles involved'.... We congratulate Mr. Parry
on the scientific value of his work, and hope that if the progress
of the colonies in the manufacture of essential oils and perfumes
equals what we are justified in expecting, it will become an
Australian handbook, everywhere appreciated."--_The Australian
