accompany the departure of such large numbers of parasites 
from the tissues is, I believe, largely due to the selective action 
of benzyl benzoate. This drug, as Macht(2) has shown, acts 
in a manner similar to papaverin, in that it tends to inhibit per- 
istalsis of smooth muscle organs, and lowers their tonicity and 
relaxes their spasm. 
It is to be noted that Mason’s -patient suffered a relapse of a 
somewhat similar nature, six days after the second course of 
treatment was administered. 
Observations I have made on this and other cases of balan- 
tidial infection, indicate the likelihood that Balantidium coli 
behaves in the tissues very much as we believe Entamoeba histo- 
lyticm - behaves. It seems likely that during clinically quiescent 
periods of the infection there is a more or less constant migra- 
tion of the parasites, in relatively small numbers, back into the 
lumen of the intestine as a part of the normal life-cycle activ- 
ities of the organism. The natural outcome to be expected as 
a result of this would seem to be the prompt encystment of the 
organism as soon as it reached the lumen, but apparently this 
does not usually occur in man. The ciliates thereupon find 
’ It will be noted that in this article the dysentery amoeba is referred to 
as Entamoeba histolytica, whereas, in the first paper of the series it is 
spoken of variously as Entameba dysenterica, Entamoeba dysenterica and 
Eyidamoeba dysenterica. Likewise, Ancylostoma is styled Ankylostoma in 
the table. Furthermore, there are allusions to “endamebiasis,” “endamebic 
dysentery,” “endamebas,” and “amebas.” This has led at least one en- 
tirely competent and discriminating reviewer, Trop. Dis. Bull. 15 (1920) 
190, to employ the accusing “(sic)” after some of these incongruities. With 
the reviewers, I have no quarrel; indeed, I am deeply grateful to them for 
unconsciously directing attention to what seems to me a growing and in- 
tolerable tendency on the part of the editors of certain medical journals 
to alter accepted zoological terms to accord with their ovra notions and 
terminology. Not only do they commit an offense against rules that have 
been adopted after much thought and deliberation on the part of entirely 
capable zoologists and which surely are as helpful to the physician as the 
zoologist in that they aid him in the interpretation of the reports of the 
zoologist, but they clog the literature with vague and incorrect terms. 
It is perhaps needless for me to say that as sent to the publisher, the ter- 
minology used in the manuscript, was Entamoeba histolytica, Ancylostoma, 
entamoebas and amoebae. The only alterations of consequence that were 
made in the copy in its preparation for the compositor were made in these 
zoological terms. The onus of the offense naturally falls upon the unof- 
fending authors — particularly the senior author — and the offense is all 
the more heinous in that he has occupied the chair of protozoology in a 
large university in the tropics for several years. Had the paper been 
written by medical men who had never specialized in protozoolgoy, the offense 
could, in a measure, have been condoned as those things have been con-
