Meteorolog-ical observations, J. E. Ostrandee, A. C. Monahan, and C. L. Rice 

 {3fa.mtchusetts Hatch Sta. Met. Bids. 139, I40, I4I, pp. 4 mc/i).— Daily and monthly 

 summaries of observations at Amherst, Mass., on pressure, temperature, liumidity, 

 precipitation, wind, sunshine, cloudiness, and casual phenomena during July, August, 

 and September, 1900, with notes on the general characteristics of the weather of those 

 months. 



Meteorolog-y, V. Boxame [Rap. An. Sta. Agron. {M<nmtiui<], 1898-99, pj>. 1-15). — 

 Observations on temperature, pressure, humidity, and rainfall during 1898 and 1899 

 are reported. The distribution of the rainfall and other features of the seasons of 

 the two years are discussed. 



Meteorological influences on the growth of beets in 1899, L. Kuntze {Ztschr. 

 Yer. Deut. Zuckerind, 1900, No. 529, II, pp. 1.53-158).— The influeuce of the season 

 on the growth of sugar beets is briefly discussed. 



An electric frost alarm, L. Burixg (Queensland Agr. Jour., 7 {1900), No. 4, j^p. 

 346, 347, figs. 2). — This is a description, quoted from Garden and Field, of an appa- 

 ratus constructed by J. Richard, of Paris. The essential feature of the alarm is a metal 

 tube, similar in construction to the one used in a Bourdon pressure gage, filled with 

 amyl alcohol. The motion caused l:>y the expansion or contraction of this tube with 

 the change in temperature is communicated by means of a metal rod to a clockdike 

 apparatus which operates a pointer on a thermometric scale. This apparatus can be 

 set so that at a given temperature an electric current Avhich rings a bell will be started.
