which are constantly taking place by the action of the sea, 

 &c. In their perusal we were forcibly struck with the truth 

 of the sentiment, that every circumstance in nature, how- 

 ever apparently trivial in itself may become of vast impor- 

 tance by its proper application, or connexion with others. 



A communication on the Flora of Wilmington, N. Caroli- 

 na, is of much value ; the more especially, as we regard all 

 such catalogues peculiarly useful, in determining with pre- 

 cision, the botany of our country. 



The article on American species of " Hispa, " by Dr. T. 

 W. Harris, will be read with pleasure. Theaccuracy of his 

 usual observations on the ceconomy of insects, and his de- 

 votedness to that branch of natural science, are sufficient 

 recommendations. We have had the pleasure, through his 

 kindness, of personally observing some of the habits of these 

 little " leaf miners," and were much delighted and instruct- 

 ed in the study. We would recommend similar pursuits to 

 our florists and horticulturists, confident that thereby, they 

 would receive, not only an inexhaustible fund of gratifica- 

 tion, but arrive at results of great importance to their profes- 

 sions. Indeed, Entomology is too much neglected by our agri- 

 culturists in general. They are yearly deprecating the evils 

 of some new or old enemy in the insect form, but are as ig- 

 norant of its ceconomy, and consequently of the means of 

 prevention, as if it were impossible to attain such knowl- 

 edge. To raise a superior vegetable, or to introduce a new 

 variety of some beautiful plant, should not be the extent of 

 a gardener's skill; but he should understand more of nature 

 and her curious productions, in order to meet and subdue, 

 or use appropriate to his advantage, every thing which might 

 aflfect him under the one or other form. 



Another valuable commimication, to the American Ento- 

 mologist, is from the pen of the much lamented Thomas Say. 

 We could wish that the various contributions to science, 

 which have emanated from him, were published in some 

 proper and connected manner, for the benefit of the scien- 

 tific world. Scattered as they are now throughout so many 

 publications, we fear that they are in a fair way to be lost, 

 unless some kind friend, or admirer of his labors, shall col- 

 lect them. 



The description of a new genus of the " Arachnides, " 

 (Latreille) accompanied with a plate ; and a chemical analy- 

 sis of " Chrysocolla" found among some ores brought from 

 Cuba, conclude the number. R.
