 Die Rohstoffe des Pflanzenreiches versuch einer tech7iischen Rohstofflehre des. 

 Pflanzenreiches. Von Dr. Julius Wiesner. Zweite Auflage, Erster 

 Band, Wilhelm Engelmann, Eeipsig. 



During the past year five important contributions to the technical side 

 of plant life have been given out by German publishers. They make 

 truly an imposing array. One is just completed, another just begun, two 

 are second editions, the fifth fills a gap in our general literature, hereto- 

 fore only covered here and there in isolated monographs. These five 

 have been here grouped together for general mention Some are so well 

 known that reviews are unnecessary. 



Throughout all of them the lesson is evident that the microscope is 

 playing a more and more important role in technical science, and perfec- 

 tion in its use a greater desideratum in the means for obtaining a liveli- 

 hood. 



It is to be greatly regretted that Tschirch's atlas is brought to a close. 

 Its careful and thorough presentation of the gross as well as microscopic 

 detail of drug structures, brought out by excellent descriptions and by still 

 more excellent illustrations has made the book an impulse to better work 

 and a delight. ^ Its authors are to be congratulated on giving the student 

 of applied microscopical science, such a trustworthy and excellent guide.
