salt of silver, the author considers the acid to be composed of 

 N C + O. The investigation, however, is still incomplete, and 

 this composition is only given as probable and open to correction. 



Like cyanogen, paracyanogen seems capable of uniting with the 

 metals to form paracyanides, though, from its insolubility in ordi- 

 nary menstrua, it is not easy to obtain them free from paracyanates. 



2. On the newly discovered microscopic Eutozoon infesting 

 the Muscles of the Human Body. I'y Dr Knox. 



The author commenced his observations by remarking that this 

 very interesting entozoon was discovered in 1833, by Mr Hilton, 

 who first saw the cysts enclosing the worms, and supposed them to 

 be cysticerci. Shortly thereafter, Mr Paget discovered the worm 

 itself. Further information was given in two excellent memoirs by 

 Dr Farre and Mr Owen ; and to the views of the former of these 

 gentlemen the author chiefly leans. 



Throughout the observations, he endeavours to shew, that the 

 origin of this entozoon is very obscure, and is not referrible to any 

 known bodily ailment or mode of life. He differs also from pre- 

 ceding observers, both in respect to the form of the cyst, its struc- 

 ture, and its connexions ; the form he makes out to be oval, the 

 structure distinctly granular and not cellulai-, that is, not composed, 

 as some have conjectured, out of the surrounding cellular tissue ; 

 and the connexion not universal, but towards the extremities. He 

 conjectures also, that the granular structure discovered by him on 

 the exterior of the cysts may be the germs of future individual 

 w^orms and cysts. 



The aged person, whose muscles after death presented these en- 

 tozoon in such numbers, was quite healthy until a short period be- 

 fore her demise.
