Mr. Rainey 9 s Researches on the Structure and Development of the 

 Cysticercus cellulosee in the Pig. 



In the year 1855, Mr. Rainey presented to the Royal Society 

 of London, a paper on the structure and development of the 

 Cysticercus celluloses as constituting the " measled pork" of the 

 London markets. An abstract of these researches was pub- 

 lished in the ' Proceedings of the lloyal Society ' for December 

 13th, 1855. They were sufficiently important as dealing with a 

 period in the history of the development of Cysticerci which had 

 not been previously accurately observed. But since that time Mr. 

 Rainey has renewed his labours ; and on the 19th of March, 1857, 

 he presented a more complete account of his researches to the 

 Royal Society, which have been ordered to be printed, with 

 Mr. Rainey's illustrations, in the ' Philosophical Transactions/ 

 Through the kindness of Mr. Rainey, I am enabled to give 

 those portions of his paper relative to the development of the 

 Cysticercus, which, with the materials added by the author 

 to the second edition of his work, will render this volume a 

 complete authority on all that has been done in reference to the 

 history of the Entozoa up to the time of its publication. 



The Development of the Cysticercus cellulosse. 



" The earliest indication of this species of Cysticercus, which admits of 

 certain recognition as a form of cystic entozoon, is the presence of a collec- 

 tion of reniform corpuscles of about ^g^th ^ an i nc ^ i n length, and 

 in breadth, mixed with very minute, highly refractive molecules
