Report on the relative humidity of southern New England 

 and other localities, A. J. Henry (/'. 8. Dept. Ayr., Weather Bureau 

 Bid. 19, pp. 23, pis. 4). — In view of the quite general belief that a humid 

 atmosphere is essential to the successful spinning' and weaving of cot- 

 ton fabrics the data obtained from observations on the relative humidity 

 at different points in New England, the Gulf Coast, the Piedmont 

 Plateau, and northern central New York have been compiled with a 

 view to " ascertaining how the natural humidity of certain portions of 

 the United States, particularly the South where the extension of the 

 art is most pronounced, compares with that of the southern shore of 

 New England." For comparative purposes similar observations at 

 different points in England where cotton manufacturing is most suc- 

 cessfully conducted are added. 



"It would appear that thus far in the development of the cotton manufacturing 

 industry little account has heeu taken of climatic conditions as affecting the quantity 

 or quality of the output. It is also apparent that the relative Immidity of the 

 atmosphere depends not only on the absolute quantity of vapor present in the air, 

 but also on the temperature which determines the point of saturation, and that these 

 elements vary both as regards time and geographic situation." 



Clothing and temperature, W. P. E. Phillips ( U. S. Dept. Agr., 

 Weather Bureau, Monthly Weather Review, 25 (1897), JVo. 5, pp. 200,201; 

 Doc. 126, pp. 6). — To study the influence of meteorological conditions 

 upon personal comfort and upon the efficiency of clothing, series of 

 observations of temperature between the coat and vest, the vest and 

 linen shirt, the linen shirt aud woolen undershirt, the undershirt and 

 skin, and under the tongue were made (1) indoors, (2) after free expo- 

 sure out of doors for 10 minutes, (3) after free exposure out of doors for 

 20 minutes, and (4) 10 minutes after returning indoors. All observa- 

 tions were made in the shade between 1.50 aud 2.30 p. m. during the 

 period from Eebruary -4 to February 16, 1897. 



The results of the different series of observations are tabulated, and 

 while no positive conclusions are deemed warranted by the data, atten- 

 tion is called to the following points : 



"The temperature of the different layers of clothing was influenced decidedly by 

 the prevailing temperature of the immediate surroundings, the former rising and 

 falling with rises and falls in the latter, but the degree of change was variable, and
