10 Voluntary Breathing. 



A correspondent suggests, that where the lungs are unu- 

 sually inactive and breathing very feeble and languid (as 

 occurs both in cases of deep thought and of mental vacuity) 

 respiration, increased both in frequency and degree, by a 

 voluntary effort, gives a quicker circulation to the blood, 

 and an increased activity to the animal spirits. He thinks 

 that in some instances, where he has felt an oppression ap- 

 proaching to pain, in the region o^ the lungs, he has found 

 himself much relieved by breathing quicker and deeper, and 

 1 he even conceives that this voluntary effort mky become a 



partial substitute for the respiration of oxigen gas.

11. Profftssor Ealon^s Geological, and Agricultural survey of Rensselaer 

 County, Dr. /. II. SteeVs report of the Geological structure of the county 



of Saratoga. 



We noticed (page 239, vol. Ul.) the geological survey of the county of 

 Albany, by Mr- Eaton and Dr. Beck, We have now the pleasure of men- 

 tioning; the survey of two other contiguous counties. The design reJ3ects 

 much honour upon those enlightened and patriotic persons, who appear as 

 the patrons of the undertaking ; and the execution is marked by so much 

 MeUty, and ability, that we think the effect must be to encourage similar 

 attempts. Geological surveys, more or less extensive, have been under- 

 taken with creditable success, in various parts of this country, but we are 

 not aware of any attempt on so extensive, and systematic a scale, to make 

 them subservient to the important interets of agriculture. It was very natu- 

 ral to look for so good, and honorable a precedent in the most powerful state 

 of the national confederacy, distinguished as it is by enlarged views, anJ 

 great and useful enterprises. 



We have neither time, nor space, in concluding the present number, to 

 do any thing more than to recommend the report of Professor Eaton, and of 



Dr. Steel, to the perusal of all those who are willing to promote some of the 

 best intprfi=fc t\f +u*.iV r^/Minirv Viv mrilrino- anipnoft thfi handmaid to the arts.

12. Yellow mineral from Sparta, JW Jersey, imbedded in white granular 



limestone. - 



We understand that a detailed analysis of this mineral, which was dis- 

 covered by the late Dr. Bruce, will soon be published by Mr. Henry Scy 

 bert, of Philadelphia, whose experiments prove it to be a silico-Jliiate m 

 magnesia.
