Queen's Microscopical Bulletin contains much excellent matter for 

 workers in science. 



A new department and additional pages are promised for 1890 for 

 Scribner's Magazine. The literary and the practical are about equally kept 

 in mind, making this one of the most popular magazines published*. 



Flora is a, high class botanical magazine, finely printed and richly il- 

 lustrated, and treats, especially since Dr. Goebel assumed editorial charge, 

 of many subjects in morphology and physiology, as well as in other de- 

 partments that are of special importance to American inv* tigators.
