572 RECORD OF CURRENT RESEARCHES RELATING TO 



one of these cysts, sliowed it to contain great numbers of Trichina 

 cysts resembling those of TricJtina spiralis, with which also the enclosed 

 worm agreed. The cyst, however, seemed to be much more developed 

 than in the pig or in man. 



Upon this curious and interesting fact the author makes the fol- 

 lowing remarks : — " I am ignorant what relations may exist ^between 

 the presence iu the same animal of Trichina and of enormous cysts 

 tilled with pus ; but the fact indicated by me appears to possess some 

 interest .... because it seems to prove that the Pachyderms, more 

 than other animals, are exposed to the spontaneous develojiement of 

 this terrible parasite — an important point which may serve to throw 

 some light upon its hitherto unknown migrations. It has been 

 attempted to explain tlie frequency of the Trichina in the pig by the 

 consideration of the voracity and filthy habits of that animal. Tlie 

 fact to which I now call attention seems to protest against this opinion, 

 for the hippopotamus by no means shares in the mode of existence 

 and the tastes of the pig, and we can hardly suppose that captivity, 

 by the special diet which accompanies it, could have a marked influence 

 ui)on the development of the Nemato^d worm. 



New Diseases of Hot-house Eubiaceae.* — M. Max Cornu says, 

 that a disease, hitherto unknown, devastated the hot-houses in France 

 last February, attacking the roots and forming swellings on the small 

 and even on the large roots. 



Transverse sections of these swellings showed, under the Micro- 

 scope, amidst the hypertrophied portions, cysts enclosing the eggs of 

 AnguiUulce in great number ; the Eubiaceae {Ixora and Hamiltonia) 

 attacked, lost most of their leaves, the rest being dried up. This 

 malady presents great analogy with that described by M. Jobert,f 

 which ravages the coffee plantations, a species of the same family in 

 Brazil. 



Adult individuals are very rare ; and the eggs exist singly, and 

 should be destroyed in this form. 



These eggs are enclosed in cysts with rather thick walls opening 

 on the outside. When hatched the AnguiUulce immediately issue and 

 make their way towards the new roots ; once established in the tissues 

 they are safe. 



It is worthy of remark that the encystment, the date of which 

 seems coincident in the two species, is in France hibernal ; in Brazil 

 it would correspond with the dry season, and be festival ; the plants 

 preserving in the hot-houses the seasons of their country. 



Female Organs of Echinorhynchus.J — Dr. Angelo Andres de- 

 scribes these structures in E. gigas, his short and very condensed 

 paper being illustrated by a folding plate of remarkably clear figures. 

 The complication of the organs renders it quite useless to attempt a 

 description of these without drawings, especially as the real nature of 

 many of the parts is by no means thoroughly understood.
