hold good for other tropical countries. As a result of our experience we 
find bugs are rarely carried about in people’s clothes except perhaps by 
those who are exceptionally dirty and never change their clothes, such 
as Tibetans and Chinese; in these cases bugs might be able to breed in 
the folds of their clothing. We have found that G. rotundatus prefers to 
breed and lay its eggs in places where it is likely to remain undisturbed, 
such as crevices in walls, doors, beds, tables and chairs. Knowing these 
facts then we can see no reason why the bed bug may not be a suitable 
transmitter of Oriental Sore. 
In appendix B, Woodcock deals with the Spii’ochaetes, and after 
referring to Schaudinn’s views regarding these parasites, dogmatically 
asserts that, “ the preponderance of opinion is decidedly against these 
organisms belonging to the Protozoa.” No references are given in 
support of this assertion, and we have no hesitation in saying it is 
inaccurate. 
Woodcock makes no mention of Spirochaeta duttoni although it is a 
blood parasite, and together with 8. carteri is the best known of the 
disease-producing Spirochaetes. Woodcock is apparently unaware of 
Breinl and Kinghorn’s (1906) experimental study of the parasite of 
African Tick Fever; also Dutton and Todd’s (1907) note on the 
morphology of the same parasite, or else he chooses to ignore these 
papers. The morphological and biological characters of spirochaetes, 
which determine their inclusion in the Protozoa, have been summarised 
by Nuttall (1908) in a recent paper, which Woodcock has also ignored. 
No reference is made to the other important blood-inhabiting spirochaetes, 
such as 8. anserina, S. theileri and 8. marchouxi and many others. 
Some of these, for instance, 8. duttoni , S. theileri and certain leech 
spirochaetes, are known to be transmitted hereditarily; these, together 
with other well-established facts, leave no doubt that spirochaetes are 
true Protozoa. 
Woodcock then deals in an unsatisfactory manner with “ Trypano¬ 
soma ” balbianii found by Certes (1882) in the crystalline style and diges¬ 
tive tract of the oyster, stating that this organism “greatly resembles (in 
structure) a true Spirochaete.” No reference is given to Fantham’s 
(1907—08) important work on this spirochaete, and it is not a fair 
statement “that Perrin’s (1906) whole paper thereon is most uncon¬ 
vincing.” Woodcock is hardly in a position to make this emphatic state¬ 
ment, unless he has personally worked for some considerable time at 
these difficult parasites, and we are not aware that he has published any 
observations on Spirochaetes. If he had studied these parasites, we feel
