megalospheric form of P. striato-punctata by fiagellispores on June 29 

 and July i. There is no mention of the reproduction of the micro- 

 spheric form by the processes we are now describing, though it is of 

 world-wide distribution, and nearly always found with P. crispa, and 

 it was the first Foraminifer ever figured — by Hooke in 1665 ' and by 

 Leeuwenhoek in 1702.' 



He was there again in the same months in 1905, but added nothing 

 of moment to his previous records, but records the fact that in 

 several of his dishes left behind in 1904, Foraminifera and other 

 organisms were still alive. 



He printed a highly condensed abstract of these later observations 

 as a postscript, dated August 3, 1894, to his Philosophical Transactions 

 paper, and this postscript, slightly elaborated, appears in" this still 

 contracted form in his later works, viz : in Lankester's Treatise on 

 Zoology in 1903," his address as president of Section D at the York 

 Meeting of the British Association in 1906," and in his Evening Dis- 

 course at the Royal Institution in 1907.^ But, for some reason which 

 we shall never know, but which was doubtless connected with his 

 state of health, he never published his paper. No apology is needed 

 therefore for giving to the scientific world his own description of 

 his researches, and their results. It is as follows : ° 



LISTER'S NOTES 



July "/, i8c)4. Plymouth. — For the last three weeks or so, I have 



kept Polysfoinella in tall glass jars,' the water in which has been 



renewed frequently by a jet playing through a muslin cover over the 



mouth of the jar.^ The Polystomellas crawl up the sides from the

 note-books, and the further details to be derived from these are of such value 

 that I have transcribed such parts of his notes as bear upon his statement, in

 Island in Plymouth Sound, and the experiments commenced on June 17.
