pecuniary outlay in the production. The work is a -gift to bryolog- 

 ical science by one of its most distinguished cultivators, who, 

 fortunately, was blessed with the means which enabled him to 

 bestow it. He accordingly fixed a price much below the cost, so 

 as to bring the work fairly within the reach of students who may 

 desire it. This policy will still be adhered to for a sufficient time 

 to enable those in this country who need the work to obtain it 

 advantageously. For the present the price of the original volume 

 will be $14.00 ; of the supplement $10.00 ; of the two together, 

 624.00. It is supplied by the American Naturalists' Agency, as 

 well as by Charles W. Sever, Cambridge, Mass., by Westermann 

 & Co., New York, and by Trubner & Co., London. — Asa Gray. 



BOTANY. 



Introduction of Ulex europ^eus in the Bermudas.— In the 

 winter of 1872-3, 1 sowed English seed of this shrub in my garden, 

 and a few healthy plants were produced in the course of twelve 

 weeks or so. Leaving for the north for the summer months, I 

 thought it best, to insure their safety, to present them to His 

 Excellency the Governor, Major General Lefroy, whose endeavors 

 to introduce new forms of vegetation into the islands are widely 

 known and appreciated. The plants died during the summer.' 

 More seeds were then sown in Government House garden and 

 came up well, and being transplanted into favorable positions, 

 throve beyond expectation, and in February last I had the pleas- 

 ure of seeing several plants, arranged as a thicket on a north- 

 western slope, in blossom. Still, I was somewhat skeptical re- 

 garding the ultimate result, knowing that this form refuses to 

 grow farther south than the latitude of 42° in the eastern hemis- 

 phere, but much to my satisfaction the legumes duly formed, and 

 the seeds became fully ripe at the beginning of this month, so that 

 the plant may now be said to be naturalized in these islands.— J- 

 Matthew Jones, the Hermitage, Bermudas, May 12, 1875. 



ZOOLOGY. 



Mr. Gentry's paper on Fertilization through Insect 

 Agency. — It is to be regretted that this interesting paper fails 

 just where it might be of scientific value. If Mr. Gentry, who, 

 by the context of the article evidently anticipated cross fertiliza- 

 tion, had enclosed a few female flowers in gauze bags, and self
