be taken than the one he has allowed himself to follow. To quote 
the views of Roubaud, Hartmann and Jollos and Prowazek in full on 
the one hand, while giving only meagre quotations from Patton, Swingle 
and Miss Mackinnon on the other, savours more of the methods of the 
“ party politician ” than of research for the advancement of Science. 
I cannot deal with this memoir in detail, for there is scarcely a state¬ 
ment in the paper that is accurate or not misrepresented. Practically 
all the authorities quoted by Mr Dunkerly have been discussed at length 
by Patton, Miss Mackinnon and myself, among others, ad nauseam. 
But I must deal with one remarkable statement in Mr Dunkerly’s 
paper, namely:—“ Grithidia cannot be applied as a generic name to any 
form, as it has simply been the name given to two stages in the life 
history of a Leptomonas or to what in other cases are probably stages of 
Trypanosomes.” This is amusing from one who has never published on 
parasites of the genus and, judging from his remarks, would 
not know a Grithidia if he saw it. For instance, he attributes a 
diagnosis of the genus to Patton, which diagnosis is inaccurate and in 
a form that Patton never used. According to Mr Dunkerly : “ Patton... 
decided that all uniflagellate parasites of insects with the kinetonucleus 
anterior to the trophonucleus and without undulating membrane, are 
to be called Herpetomonas and that those having the kinetonucleus 
posterior to the trophonucleus and possessing an undulating membrane, 
should receive the generic name of Grithidia.” Patton never used the 
terms “ trophonucleus ” and “ kinetonucleus,” and certainly did not say 
that in Gidthidia the blepharoplast was always posterior to the nucleus. 
Another statement made is also an unworthy one, namely:—“ Luhe 
and Hartmann and Jollos have pointed out that Patton’s failure to see 
the characters observed by Prowazek and others does not prove their 
non-existence.” But Lirhe (as listed) wrote in 1906 and Patton in 
1908. Further, Patton never denied the existence of certain features 
in Herpetomonads, but disagreed with their interpretation as given by 
Prowazek and others—a very different thing. As to Hartmann and 
Jollos, I am sorry that I cannot seriously consider their second-hand 
views, for these authors, among other items, place Piroplasma {Babesia) 
and the malarial parasites in their “ Flagellatenordnirng Binucleata,” 
despite lack of supporting evidence. 
Mr Dunkerly appears to lay much stress on his edition of Leger’s 
statement that Grithidia is “ en form (sic) de grain d’orge.” Leaving 
aside the words used in description, let us consider the figures of Leger. 
If Mr Dunkerly can find \ any important difference in the figures
