Comparative tests of methods for determination of total 



PHOSPHORIC acid IN SAMPLES CONTAINING ORGANIC MATTER, J. A. 

 Fries (pi>. 100-192). — A comparison was niad<' on a nnmher of orp:anic 

 materials containin<i- i)hosphoric acid of dissolvinji the phosphoric acid 

 (1) in nitric and hydrochloric acids, (2) by dijrestinjj with sulphuric acid 

 and adding: small quantities of potassium nitrate. (3) by ignitinj; with 

 maiiiiesium nitrate and dissolving in nitric and hydrochloric acids, and 

 (4) by ijjnitiufr with the addition of silica and dissolving in nitric and 

 liydrochloric acids. "Igniting the sample mixed with powdered silica 

 before dissolving has proved to be the most reliable iu the presence of 

 organic matter." 



METEOROLOGY, W. FiJEAPv, PH. D. (pp. 193-210 and 217-2(M).— The

 sunshine, soil temperatures, aiul soil moisture. ^Monthly summaries of 

 the meteorological observations and weekly crop reports are given in 

 the body of the Beport and the detailed record of daily observations in
