be followed, is to study fully the rules of grammar, and to practice 

 them unremittingly. It is principally by its capability of serving 

 this great purpose, that one language is considered as more impro- 

 ^ved, or more nearly approaching to perfection, than another. 



It is of importance to observe that the art of grammar goes no fur- 

 ther than to assist us in avoiding ambiguity. It furnishes no new 

 means of conveying our sentiments. These the speaker or thevs^ri- 

 ter must derive from that command over language, vi^hich his mem- 

 ory, his experience, and his associated ideas, give him. In this res- 

 pect, the art of grammar is on a par with the art of criticism. The 

 latter can only teach the poet or the orator to avoid errors. It cre- 

 ates no new faculties ; it imparts no new powers. It simply directs, 

 and guards from more glaring errors, those powers which nature has 

 bestowed. Every practitioner in these elevated arts, and the con- 

 nected ones, must seek for the means of great performances, in the 

 resources of his own mind, in the vividness of his conceptions, and 

 the boundless extent of his associations. 



To conclude, all the physical sciences may in time, and after 

 great improvements, be reduced to the form of exact sciences. 

 Morals and literature, from the nature of the subjects of which they 

 treat, must, however improved, be for ever excluded from that class. 



Art. IV. — Chemical Aiialyses of Mineral Waters from the Azores ; 

 by Charles T. Jackson, M. D. 



No. 1. Four bottles of water, carefully sealed at the boiling tem- 

 perature. MarJc, " No strings on necks of bottles." 



This water was taken from the centre of the Great Geyser, by 

 Dr. Webster. 



On examination, there appears to be a partial vacuum over the 

 water, so that it has evidently been well secured, and the water does 

 not contain any gas in solution. When uncorked, no odor is per- 

 ceptible. The water is transparent. A few flocculi of siliceous mat- 

 ter separate on standing. Tested for free acid, by blue litmus pa- 

 per, none discovered. Reddened litmus paper is turned blue, and 

 turmeric paper brown by the water. Hence it contains a free al- 

 Jcali. A portion of the water, neutralized by hydrochloric acid, was 

 tested for metallic salts, precipitable by liquid sulphuretted hydro- 

 gen, and by hydro-sulphate of ammonia, — 7ione discovered. Apor-
