A NEW GENUS OF MYRTACEjE. 153 



the fluid's consisting of serous exudation from the blood as well as 

 of sweat ; it may, and perhaps does, consist of perspiration alone. 

 It is, moreover, uncertain whether there is any increase in the 

 amount of fluid escaping from the soles of persons suffering from the 

 disease ; and if there is, whether such increase may not be due to 

 warm weather. It is perhaps not impossible, however, that the 

 ferment may be the direct cause of an increase of the fluid, the 

 immediate agent being the ammonia liberated by the ferment's 

 growth and absorbed into the tissues of the soles. 



Another matter worthy of note is the greater chemical energy 

 of the soil-ferment as compared with that of the Bacterium. This 

 has already been mentioned in speaking of the reduction of nitrates, 

 and it was observed in varying degree throughout the experiments. 

 The reason is, I believe, that the supply of soil-cocci to the test- 

 glasses was more lavish than of the Bacterium, on account of the 

 greater difficulty of collecting the latter by the method adopted, and 

 this rule was borne out by inspection of cultures in their early 

 stages. Dr. Thin failed to find upon the fetid socks anything but 

 cocci. This would seem to show that in perspiration (possibly in a 

 mixture of perspiration and serum) the history of the Bacterinm is 

 simply a multiplication of cocci. On account of the difficulties in 

 the way of obtaining perspiration in sufficient quantity to allow of 

 sterilisation, I have not determined whether this is the case. For 

 the same reason the experiment with perspiration is to be con- 

 sidered as inferential merely.

Pseudoeugenia, n. g. — Calycis tubus turbinatus, ultra ovarium 

 productus annulo staminifero baud crasso donatus, limbi segmentis 

 4, parvuhs, rotundatis. Petala 4, orbicularia unguiculata. Sta- 

 mina 8, ordinate inserta, 4 oppositipetala, 4 oppositisepala filamentis 

 brevibus deorsim expansis, in alabastro inflexis, antheris bilocu- 

 laribus, loculis parvis apice filamenti more versatibilium insiden- 

 tibus. GlandulaB nullte. Ovarium 2-loculare ; styhs brevis ; ovual

 serie 4-5 Fructus Eugenia-, semina 1-2. Embryo . . . Arbor, 

 foliis oppositis punctatis, inflorescentia axillaria, bracteis parvis. 



Genus inter Myrrhinum ac Eit//eniavi locandum, gradu Eugenia'. 

 propior accedit quam Ni/rrJiina, quamquam cum Alj/rrhino com- 

 munem liabeat staniinarum numerum. Habitu Eugnna-, eam 

 fallaciter imitatur. Nisi staniinarum numerum attend'eres, Euge-

 Eugenia recipi nequit.
