1024 EXPERIMENT STATION RECORD. 



A source of error in the Kjeldahl method of determining nitrogen, W. Holt- 

 schmidt (Chem. Zta., 21 {1897), Xo. S3, p. S71). — Tests are reported which confirm 

 Sjollenia's conclusions regarding the error due to the carrying over of soda in dis- 

 tillation, especially when zinc dust is used instead of granulated zinc. 



A method of acidimetry for approximate determinations, R. Cimmino (Ann. Iij. 

 Sper., n. ser., 6 (1896), Xo. 3, pp. 417-423).

 puruo (Ztschr. Nahr. Untersuch. u. Jfm/., 12 (1S9S), Xo. 4, pp. G9, 70). 



Abnormal iodin number for lard, A. Fehnau (Ztschr. Nahr. Untersuch. u. Hyg., 

 12 {1898), Xo. 4, p. GO). 



Apparatus for detecting sesame oil in butter and margarin -when artificial 

 coloring matter is present, C. A. Neufeld {Ztschr. Untersuch. Nahr. u. GenussmtL, 

 1898, Xo. 3, pp. 156-158, fig. 1). 



The estimation of starch in sausage, II. Weller {Ztschr. Untersuch. Nahr. u. 

 Geimssmtl., 1S98, Xo. 3, pp. 167-171).

 Sciimelck (Christiania, 1S97, pp. 16). 



Division of chemistry, A. M. Peter (Kentucky Sia. Bpt. 1896, pp. XI-XXIIT). — 

 Analyses of 19 samples of hutter made on the station farm; sugar and food constitu- 

 ents in 21 samples of sorghum and 18 of sugar beets; food constituents in 1 sample 

 each of korseweed (Ambrosia trifida) and germ feed; and the fertilizing constituents 

 in 5 samples of tobacco grown on the station grounds with different fertilizers, 7 sam- 

 ples of tobacco stalks, and 1 sample each of tobacco extract refuse, nitrate of potash, 

 double potassium and magnesium carbonate, and wheat bran are reported, with the 

 results of the examination of 6 samples of mineral waters and 1 of calcareous sand- 

 stone. 



The examination of agricultural and commercial products, J. Konig (Die 

 Untersuchung landwirtschaftlich und gewerblich wichtiger Stoffe. Berlin: Paul Parey, 

 189S, 2. cd., pp. 824, pi. 1, figs. 248). — A revised edition of this practical laboratory

BOTANY. 



Report of the botanist, II. Garman (Kentucky Sta. Bpt. 1896, pp. 

 XXVIII-XXXIV, pis. 2). — A considerable portion of the botanist's 

 attention Las been devoted to a study of the woolly mullein ( Verbascum 

 phlomoides), and attempts have been made to secure its eradication. 

 It seems to be contined to very few counties of the State. It is believed 

 that the methods adopted were successful in greatly reducing - the num- 

 ber of the weeds. Concerning - the ease with which the weed may be 

 destroyed and the slowness with which it seems to be disseminated, 

 the author believes that another season's work would practically eradi- 

 cate it. In appearance the woolly mullein somewhat resembles the 

 common mullein of the fields. 



Some attention was also given during the season to the subject of 

 broom rape of hernp and tobacco, and it was found that in addition to
