| Notes | Masanori Ogata an P. L. Simond. Ackerknecht gives Simond and Ogata, in that order, but he and Lee agree on the year 1897. [This is also the year in which Ross made his key observation on the transmission of malaria by mosquitos.] See 1898 Simonds. Garrison gives year as 1898, and spells author as Simonds in text and as Simond in index. |
