In histological character* the grain* of Brunsdonna 

 sandtra; a' 1 .1 arc in form closer, on the whole, to those 

 'rlladonna, but in tome respects closer to 

 Hrunsri'iia joftfiliimr. A tjpe of grain peculiar to this 

 not.-d which consists of an amorphoua-looking 

 mass composed of a number of fused grains adherent to 

 the side or distal end of a large grain-mass, all inclosed 

 in !' to 12 larnellm. The hilum more closely resembles 

 that of Amaryllis belladonna; the lamella- in furm and 

 arrangement are closer to those of Amaryllis belladonna, 

 (nit in number they are closer to Brunsvigia josephimr; 

 in size and in proportions of length to breadth they are 

 closer to Amaryllis belladonna; in polariscopic figures 

 and linos and selenite reactions and in the qualitative 

 iodine reactions they exhibit a closer relationship to 

 Amaryllis belladonna. The qualitative reactions with 

 the chemical reagents are, on the whole, much closer to 

 i"iiryllis belladonna than to Brunsvigia josepkince. 



In '; -'"logical characters the grains of Brunsdonna 

 mnitrtr are in form much nearer to those of A maryllis 

 belladonna than to those of the other parent, but they are 

 > near those of Amaryllis belladonna as those of the 

 other hybrid, and not so near Brunsvigia josephina in the 

 mmil*T and type of compound grains as those of the other 

 hybrid. The hilum is the same as in the other hybrid, and 

 hence nearer that of Amaryllis belladonna. It differs from 

 the hilum of the other hybrid in being less often fissured ; 

 hut it is more often fissured than in either parent. In 

 character and eccentricity of the hilum these prains are 

 nearer those of the parents than those of the other hy- 

 brid. The lamellir in character and arrangement closely 

 resemble those of the other hybrid and are closer to those 

 aryllis belladonna than to those of the other parent, 

 hut in nuniliers they are closer to Brunsvigia Josephine. 

 In the ratio of length to breadth of the grains, and in 

 larger grains in length, it is nearer to Amaryllis bella- 

 donna; but in the length of the common-sized grains 

 it is nearer to Brvnsviyia josephina. In polariscopic 

 properties in the character of the figure and appearance 

 with telenite this hybrid is closer to Amaryllis bella- 

 donna than to the other parent, but not so close as the 

 other hybrid. In qualitative iodine reactions it is closer 

 'aryllis belladonna. Imt not so close as the other 

 hybrid. In the qualitative reactions with the chemical 

 nta close relationship is shown to Amaryllis bella- 

 donna and to the other hybrid, but closer on the whole 

 to this parent than to the latter. In some respects the 

 reactions are closer to Brunsvigia joiephina than to 

 Amaryllis belladonna, showing the influences of both 

 parents. In the chloral -hydrate, nitric-acid, potassium- 

 sulphocyanate, and sodium-salicylate reactions it is closer 

 to Amaryllis belladonna than to the other hybrid, but 

 in the cobalt-nitrate, copper-nitrate, and cupric-ohloride 

 reactions it is closer to the other hybrid.

The starch of Amaryllis belladonna in comparison 

 with that of Hrunsriyiti josrjthintT shows higher polariza- 

 tion and safranin reactions, and lower iodine, gentian-

 in the gentian-violet reactions they show greater close- 

 ness to Brunsriyiii jinrjthinir, the closer lieing Hruns-

This section considers velocity-reaction curves of the 

 starches of Amaryllis belladonna, Brunsvigia josephina, 

 Brunsdonna tandera alba, and Brunsdonna tandera, 

 showing the quantitative differences in the behavior 

 toward different reagents at definite time-intervals.

The Amaryllis and Brunsriyia curves tend, in reac- 

 tions with nitric acid, sulphuric acid, hydrochloric acid, 

 potassium hydroxide, potassium iodide, potassium 

 sulphocyanate, potassium sulphide, sodium hydroxide, 

 sodium sulphide, uranium nitrate, cobalt nitrate, and 

 barium chloride, to keep very close together; while in 

 reactions with chloral hydrate, chromic add, pyrogallic 

 acid, sodium salicylate, calcium nitrate, strontium 

 nitrate, copper nitrate, cupric chloride, and mercuric 

 chloride there is a well-marked separation during MUM 

 important part, or the whole, of the 60-minnte period. 

 In the chloral-hydrate reactions the curves are very close 

 up to the 15-minute record, at which time they begin
