tortuenso, janne, foriiiee i^ar hi rencontre de denx ecorces op|X)sees, 

 et qui semblait avoir ete destinees a circonserire line cavite, mais 

 qu'iine cause quelconque avait detruite par la pre.ssion." In this 

 case the oil-glands of the central peel are shown in the same direc- 

 tion as those of the outer peel, whereas in that of Dr. Masters the 

 two strips of central peel were twisted, and the oil-glands were in 

 the opposite direction to that of the outer peel. 



In l)oth cases, however, the central peel has no corresponding 

 pulp-carpels, so that if we accept hypothesis (a), these inner peels 

 \so\\\i\hei\\Q outer sides of carpels left stranded by the desertion 

 and suppression of their inner sides I 



Botli these sjjeciniens clearly indicate to nie that the ])eel, like 

 the pulp, is made up of distinct phyllous organs. 



Dr. Masters ga\ c me another specimen, which is of common 

 occurrence, viz., an orange complete within an orange. This, I 

 consider, is a complete doubling of the fruit, much as we see the 

 doubling of a daffodil, viz., the .sepals and petals repeated. In this 

 orange the peel and Cfupels were repeated alternately with their 

 own colours, just as the sepals and ])etals of certain daffodils, in 

 doubling, are repeated ivith their own colours. 



(d.) In the teratological specimen (lingered citron) shown in 

 pi. 139 of "Cultivated Oranges and Lemons of India 

 and Ceylon," and in Figs. 143 and 144 of these Notes, 

 there were two whorls of what seem to 1)e a 

 reversion of carpels; an outer whorl, consisting of 13 

 distinct fingers, and an inner wliorl, consisting of seven 

 distinct lingers, shown in Fig. a of that plate. Both 

 the.se whorls had the character of peel, and were not 

 opposed to each other, as if they were the inner and 

 outer lamiucE of one carpel, as shown in section, Fig. 144. 

 Moreover, there was nothiu"; in tliis tinoeird citron 

 which could be taken for pulp. 

 (e.) I have seen many specimens of citrons Avhich had 

 the surface divided into cohering segments, as if 

 they descended fiom distinct phyllous members, such as 

 are shown in pis. 145, 147, 150, jiiul many other.s, of 

 "Oranges and Lemons of India," AVell, the pulj) 

 segments (or quarters) did not coirespond to the peel 

 segments, but were like the segments of Fig. 144, as if 

 the two were independent whorls. It might be said
