it undergoes on keeping (Dr. Voeleker), 

 xvii. I'Jl ; uniform Siunples difUeidt to 

 be obtiiined, 193 ; fresh dung, its ana- 

 lysis, 194; proportion of ammonia in 

 tlie natiual and the dry states, 195; 

 analysis of ash, soluble and insoluble, 

 196; analysis of dry manure kept fiee 

 from rainiall, 198; freslx maiuu-e con-

 ash gives indications of potash, silicate 

 of potash, and soluble phosphate of 

 lime, 200 ; home-made dung a uni- 

 versal manure, 202 ; analysis of rotten 

 dung, 6 months old (203), gives in- 

 crease of soluble phosphate (204), but 

 less potash, 205 ; fresh and rotten dung 

 contrasted, 207; rotten dung rich in

oxygen, ib. ; the process of putrefac- 

 faction (208) accompanied with the 

 evolution of sulphur and pliosphorus 

 with hydrogen (209), and forming vola- 

 tile gases, such as carb. acid and ammo- 

 nia, and soluble coini)ounds, such as the 

 humates and ulmates of the alkalies, 

 210 ; tlie union of ammonia with humio 

 and ulmic acid destroyed at elevated 

 temperatures, ib. ; exposure to weather 

 removes bone-earth and solul)le silica, 

 217 ; analysis of manure icept luider 

 cover, once watered, 218; aflbrded few 

 indications of change in 3 montlis, 220; 

 formation of sulplnu'ic acid and gypsum 

 in rotten dung, 221 ; loss of soluble 

 constituents in manure exposed to 

 weather, 225; escape of soluble nitro- 

 gen, ib. ; hot interiors of manure-heaps 

 give olf ammonia, which is fixed again 

 by the coolness of the outer layers, 

 22G ; loss of annnonia in turning heaps, 

 ib. ; table of loss of weight sustained 

 by keeping manure for different periods, 

 227 ; comj)osition of ditto at the dif- 

 ferent experimental weighings, 228 : 

 effects of riiinfall, 229 ; composition of 

 fresh maiuire, exposed, calculated dry, 

 ib. ; no advantiige in keejiing manure 

 too long — after 3 months little increase 

 in percentage of nitrogen, and enor- 

 mous waste of organic matter, 230 ; 

 but well regulated fermentation neces- 

 sary (232), and very little volatile am- 

 monia is formed during the process, 

 233 ; rainfall the chief cause of waste of 

 fertilising materials, ib. ; loss in weight 

 of manme kejjt under shed, table of, 

 235 ; fresh manure does not jtroperly fer- 

 ment under cover, 238 ; fermentive 

 action ceases with less than 5G pur cent, 

 of water, ib. ; table of composition of ma- 

 nure heap at different dates. 239 ; small 

 loss of nitrogen, as volatile carb. of

 tables for increase of mineral matter, 

 230 ; tables of the comjiosition of well- 

 rotted dung exposed, 251 ; its loss in 

 weight far less than its loss in value,
