 publications include the following : 



Annals. Vol. LYI, No. II, Stars having Spectra of Class B. 



Vol. LVIII, Part I. Observations and investigations made at 

 the Blue Hill Meteorological Observatory, Massachusetts, under 

 the direction of A. Lawrence Rotch. This part, of 62 pages, is 

 devoted to a discussion by H. Helm Clayton of the diurnal 

 and annual periods of temperature, humidity and wind-velocity 

 up to 4 kilometers in the free air and the average vertical gra- 

 dients of these elements at Blue Hill. Among other points of 

 interest, it is shown that there is a rapid increase in wind-velocity 

 from the ground to 500 meters, the rate being about twice as 

 great in the night as in the day. From 500 up to 1000 meters, 

 there is a slow increase in wind-velocity during the day but, in 

 the average, a decrease by night. Above 1 000 meters there is a 

 steady increase of wind-velocity and the rate grows larger with 

 increasing height.

 — This new journal has been recently started to give an organ for 

 the presentation and discussion of scientific papers bearing on 

 agriculture. It is proposed to issue the Journal as material accu- 

 mulates, in parts of about 100 royal 8vo pages ; a volume will 

 contain four parts. Subscription (84.50, single numbers $1.50) 

 may be made to the Macmillan Co., New York City.
