11. Report on the Insects of Massachusetts, injurious to Vegetation. 

 By Thaddeus William Harris, M. D. Published agreeably to an 

 order of the Legislature, hy the Commissioners on the Zoological and

 niary recompense. We hope to be able to speak more particularly 

 of Dr. Harris's Report, at some future day.

" C'est dans cet etat de la question," — namely, after M. Landriu, 

 having completed the list of metallurgic writers anterior to the reform- 

 ation of the phlogistic theory, has farther illustrated the subject by 

 reference to the systematic and learned labors of Hafrenfratz, the 

 immense scientific and practical knowledge of M. Karsten, and the 

 supplementary critical memoirs of M. Miiller, — " que Samuel Roger 

 de Risca, metallurgiste aussi eclaire que modeste, redigeait en Angle-
