642 General Notes. [June, 
ZOOLOGICAL Nores.—/yrotozoans.—Kunstler describes Tricko- 
monas vaginalis as extremely protean in external form. Pseudo- 
podia arise over the general surface, or are localized at the posterior 
end.——G. Klebs discusses (Bot. Zeitung, 1883), the relationship 
of the Flagellata to the Algz and Infusoria. Some Flagellata inthe 
older sense are referred to the lower chlorophyllaceous Alga; such 
are, in addition to the Volvocine, the Chlamydomonads. The 
fresh-water forms of the Peridinez are, with Leuckart, regardedas 
plants. The Euglenacee and Peranemez are separated from the 
Ciliata and placed among the Infusoria. ; 
Crustaceans.—A remarkable shrimp (Nematocarcinus gracilipes) 
was dredged by the Za/isman at a depth of 850 meters, which is 
analogous to certain blind cave phalangids in the enormous 
and slenderness of the antennz and legs. The eyes are lange 
and well developed, though the stalks are short. In a new form 
(Acanthephyra pellucida) the feet are adorned with phosphorescent 
bands 
Mammals.—Miklucho Maclay finds that the average temper 
ature of the body of Echidna hystrix is 78° F., or very little mor 
than that of fish, and about 25° less than mammals generally" 
So far as known, congenital deafness is only known to © 
besides man in the cat, and always in white ones, and most us 
in females. 
PHYSIOLOGY.’ — 
THE PHYSIOLOGY OF THE CARBOHYDRATES.—In te nal 
Lancet of Januury and February, 1884, Dr. Pavy reco ae 
interesting experiments which prove the presence in the mee 
and intestines of znimal ferments which have been pani ; 
known. Dr. Pavy’s general object was to discover the s 
carbohydrates in the animal system : 
1. Solutions of grape sugar placed in contact ntly killed rabbit, 
ing the 
of reducing Fehling’s solution than grape mop i
