 Samples of Norwegian herring cakes and whale- flesh meal were sub- 

 jected to chemical examination, including determination of digestible 

 nitrogenous components (according to Stiitzer's inetliod). The main 

 results are given in the following table, and, for comparison, an analy- 

 sis of a wliale-tlesli meal made by Stutzer in 1884:

If the total digestible protein be compared in case of samples 2 and 

 3, we find that sample 3 contained 3.G6 per cent more of digestible 

 nitrogenous snbstances than 2, and 7.77 per cent more of digestible 

 albuminoids. In the report of the Christiania Station tor 1893 the 

 authors call attention to tlie fact that the quality of the whale-flesh 

 meal on the market has deteriorated of late years throngii carelessness 

 on the part of the manufacturers in removing the oil. The following 

 analyses of whale-flesh meal corroborate the conclusion drawn:

The relative nutritive values of mangel-wurzels and sugar 

 beets, r. Gay {Ann. Ayron., 20 {1891), Xo. 4, pp. 200-207).— Ten 

 Merino sheep divided into 2 lots were used. Both lots received the 

 same kind and amount of coarse fodder and roots containing 420 gm. 

 of dry matter per head daily. This dry matter was supi^lied to one 

 lot in the form of mangel-wurzels containing 14 per cent dry matter 

 and to the other lot in the forjn of sugar beets averaging 19 per cent 

 dry matter. At the end of 2 weeks the feed for the lots was reversed. 

 Witli both lots the dry matter of sugar beets had a superior nutri- 

 tive eflect, the average gain in live weight due to sugar beets being 

 about 20 per cent greater than the increase resulting from feeding 

 mangel-wurzels.
