OX THE LIMITATION OF THE AREA ADAPTED TO COTTON 



CULTURE. 



The following- is a resume of a paper on the reciprocal interest of the cotton 

 planter and cotton manufacturer, read at the last meeting of the British 

 Association, by Mr. Dawson. The following series of propositions was laid 

 down : 



1. That cotton, from the condition of climates necessary to its culture, can- 

 not be grown in Europe, but that, with the single and not important excep- 

 tion of the factories in the New England States of America, it is and must 

 long continue to be manufactured almost exclusively in Europe. 2. That the 

 present supply is chiefly raised, and for the present must continue to be 

 raised, by slave labor seeing that while, for fifty years, we have sought over 

 the whole earth for cotton, we have during that tune continued to obtain 

 from the slave states of the American Union a continually increasing propor- 

 tion of our entire supply. 3. That two-thirds in number at least of the slave 

 population of the United States have been called into existence, and are now 

 directly or indirectly maintained, for the supply of cotton for exportation. 

 4. That of the cotton thus exported, three-fourths at least in value are raised 

 for and sent to Great Britain alone. And 5. That of the entire quantity we 

 import, four-fifths at least in value are thus derived from the United States. 

 Each proposition was supported by tabular accounts extracted from the 

 public records of Great Britain and the United States, and the conclusion was 

 expressed thus: ' ; That hence, in the present state of the commercial rela- 

 tions of the two countries, the cotton planters of the United States are inte- 

 rested to the extent of two-thirds at least of their entire exportable produce in 

 the maintenance of the cotton manufacture of the United Kingdom ; and that 

 reciprocally the cotton manufacturers of the United Kingdom, and through 

 them the entire population of the kingdom, are interested, to the extent of 

 more than four-fifths of the raw material of that manufacture, in the existing 

 arrangements for maintaining the cotton culture of the United States." 



OX THE RELATIOXS EXISTIXG BETWEEN ANIMALS AND MAN. 



In a late number of the American Journal of Medical Science, Dr. J. Jones 

 gives some very curious and interesting facts in relation to animals and man. 

 In nature there are two great kingdoms, the animal and vegetable. Dr. Jones 

 contends that both have one common origin the organic cell the distinction 

 between the two kingdoms every day disappearing, most of the organic pro- 

 ducts which were thought to distinguish the animal from the vegetable 

 having been found in both ; and motion even no longer separates the animal 

 from the vegetable world. This property of matter appears to be most inces- 

 santly occupied in the minutest organisms ; the motion of the minute cilise 

 of vegetables, the contraction of the leaves of the sensitive plant, are familiar 

 examples. The only distinction between the lowest orders of the two 

 kingdoms, the Protozoa and Alga?, is that the former possess to a certain 

 extent voluntary motion. In the vegetable kingdom the rudiment of nervous 

 apparatus, or a cell-generating nervous force, has not been discovered,
