Pneumonia depresses the resistant vitality of the tissues, and thus affords to the diplococcus present in the saliva an excellent nidus for its growth.
Diplococcus pneumoniæ and streptococcus, and association amongst the various suppurative organisms, we cannot doubt that there is an explanation to be found here of many hitherto unsolved results of bacterial action.

It must further be borne in mind that a dividing micrococcus assumes the exact appearance of a diplococcus during the transition stage of the fission.

This form of meningitis, which is due to the diplococcus intracellularis, may occur sporadically, but is more frequently met with in an epidemic form.
The absence of the diplococcus intracellularis helps to differentiate the disease from cerebro-spinal meningitis, which it may closely simulate.
Though by those who are more precise it is still known as the Diplococcus pneumoniæ or Diplococcus lanceolatus, from its faculty of usually appearing in pairs, and from its lance-like shape.
For instance, not a few healthy noses and throats contain the bacillus of diphtheria and the diplococcus of pneumonia.
