more specimens. The third column is computed from formula 1), and the next two from 

 formulas 2) and 8), respectively. 



Measurement Capacity in cubie inches. 



The percenta<;e of mean variation to bulk 

 for the three last columns is .08 1-4, .11 1-3, 

 and .11 5-0, respectively. The sum of the 

 column "by weight "" is taken as a basis of 



comparison, and the sum of the variation 

 from each of the other columns reduced to 

 hundredths.

Influence of the Open Winter 

 1889-1890 on the Nesting and 

 Arrival of Some Birds at 

 Raleigh, N. C. 



of 



Owinti' to the universally mild Avintcr of 

 18S'.)-90, many birds began nesting earlier at 

 Raleigh, the following list showing better than 

 any other way how much several S2)ecies were 

 influenced by the weather. 



Barred Owl. First set taken April 9, 18S8, 

 (addled); iMarch 18, 1889, (large embryos); 

 March 14, 1890, (slightly incubated). 



Pine Warbler. First set taken April 9, ISSS; 

 April 12, 1889; March 24, 1890, (small embryos). 



Brown-headed Xuthatch. First set taken 

 April 7, 1888; April 0, 1889; March 24, 1.S90. 



Carolina Chickadee. First set taken April 

 21, 1888; April 19, 1889; April 3, 1890. 



Ruby-throated Hummer. First set taken 

 May II, 1S88; May i:'., 1889; May 7, 1890. 



Yellow-throated Warbler. First set taken 

 May 11, 1888; May 4, 1889; April 22, 1890. 



Those si)ecies that nested early were much 

 more influenced by the eaily spring than the 

 later nesters, ;iii(l the resident species more 

 than the summer visitors, in fact the latter 

 were very little if any earlier than usual. The 

 earlier migrants were also induced to come a 

 little earlier, but hnrdlv so much as might be 



expected, as will be seen from the instances 

 given below.
