APPENDIX. 



Of tlie tables contained in tlie Appendix, I. and IT. are 

 essentially those of Jnlius Kulm {Mentzel <& v. Leiigerle's 

 Lcmdw. Kalender^ 1880), and III. and IV. are from "Wolff. 



As regards nninerieal accnracy, tliere is little difference 

 between Kahn's tables and Wolff's, the averages of the 

 former being mostly identical with those of the latter. As 

 will be seen, Kuhn's contain, in addition to the average 

 composition and digestibility, the range of variation hither- 

 to observed in these respects, and thus afford a better means 

 of estimating the composition of particular feeding-stuffs* 

 (Compare page 467, and also the remarks in the preface,.) 



In Table I. Wolff's 'classification of meadow hay and 

 clover hay has been introduced, and averages of all a^vail^ 

 ble analyses of American feeding-stuffs have b^en giv^n. 

 Tor the latter the author is indebted to the valuable oom« 

 pilation of Dr. E. II. Jenkins, published in the '* ifceport 

 of the Connecticut Agricultural Experiment Station ^ for 

 1879. In Table II. "Wolff's classification of hay has also 

 been introduced, and likewise the results i^eeently obtained 

 by Wolff in experiments on the horse {Landnjo, JahrW^'hr 

 er, VII., Supplement I.). In regard to the manner of 

 nsing tke tables, compare Chapter VII., of Part IK 



In all the tables "protein" signifies nitrogen x 6.35; 

 that % it includes gelatin, amides, and all other f orm$ of 

 non-protein.
