 Press Opinions. 



"There can he no doubt that the publication will take a high place in the list of scientific 

 text-books." J^ondon A rgus. 



" We can heartily recommend this volume to all interested in the subject of essential oils 

 from the scientific or the commercial standpoint." British and Colonial Druggist. 



" Mr. Parry has done good service in carefully collecting and marshalling the results of the 

 numerous researches published in various parts of the world." Pharmaceutical Joumai. 



"A most useful appendix is inserted, giving a table of constants for the more important 

 essential oils. . . . This, in itself, is of sufficient importance and use to warrant the publication 

 of the book, and, added to the very complete classification and consideration of the essential oils 

 which precedes it, the volume becomes of great value to all interested." Glasgow Herald. 



"At various limes monographs have been printed by individual workers, but it may safely 

 be said that Mr. Parry is the first in these latter days to deal with the subject in an adequate 

 manner. His book is well conceived and well written. . . . He is known to have sound practi- 

 cal experience in analytical methods, and he has apparently taken pains to make himself an fait 

 with the commercial aspects of the subject." Chemist anil Druggist. 



" Mr. Parry's reputation as a scientist is fully established, and we can therefore accept any 

 work emanating from his pen as being of the greatest practical value. We have perused the 

 work before us with much care, and are convinced that the contents will he found most service- 

 able and its publication most 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 hand-book, 

 everywhere appreciated." -The Australian liract T.S' Journal.
