The fresh ‘Bombay Duck’ (Harpodon nehereus) has a normal bacterial flora of its own, among whichBacterium phosphoreum andSarcina littoralis or their variants predominate. The latter species also persists in the dehydrated variety of the fish, which otherwise presents a microbial picture, totally different from that of fresh fish. Besides the species mentioned, the fresh fish is also associated with an adventitious flora, in which the following genera are represented:Escherichia, Aerobacter, Micrococcus, Gaffkya,Achromobacter, Flavobacterium, Bacillus andPseudomonas. The occurrence of a large number and variety of micrococci in the dehydrated fish has a probable epidemiological significance.

Substances that depress metabolism suppress relaxation of unloaded muscle and increase that of loaded muscle.
It is therefore concluded that relaxation in unstriated muscle is of two kinds, one active and the other passive.
Substances that increase metabolism may diminish the mechanical response, by simultaneously increasing active relaxation, while the muscle is contracting.

The effect of various substances on the contractile mechanism of frog’s sartorius and rectus has been studied by using the dying muscle.
It has been found that the effect of various substances on the frog’s striated muscle resembles that onMytilus unstriated muscle and not that on frog’s unstriated muscle.
The common feature of frog’s striated muscle andMytilus muscle is, that active relaxation is absent in these muscles.
