The old proverb, "When want comes in at the door, Love flies out at the window," might be revised to read, "When sunlight comes in at the window the pneumococcus flies 'up the flue." Authorities are still divided as to the meaning and even the precise frequency of the occurrence of the pneumococcus in the healthy human mouth.

PLEURISY. Inflammation of the pleura is most common in horses. It occurs in all farm animals and is frequently unilateral. There are two forms of pleurisy, acute and chronic. Pleuropneumonia is common when the cause is a specific germ. This occurs in tuberculosis, pleuropneumonia of horses and pneumococcus infection.

Now that we know that under decent and civilized conditions of light and ventilation the pneumococcus will live but an hour to an hour and a half, this reduces the risk of direct infection under these conditions to a minimum. It is obvious that the principal factors in the control of the disease are those which tend to build up the vigor and resisting power of all possible victims.

With breezy fatherliness which inspirited Una, he spoke of the possible presence of pneumococcus, of doing magic things with Romer's serum, of trusting in God, of the rain, of cold baths and digitalin. He patted Una's head and cheerily promised to return at dawn. He yawned and smiled at himself.

#Pneumococcal affections of joints#, the result of infection with the pneumococcus of Fraenkel, are being met with in increasing numbers. The local lesion varies from a synovitis with infiltration of the synovial membrane and effusion of serum or pus, to an acute arthritis with erosion of cartilage, caries of the articular surfaces, and disorganisation of the joint.

Said to have been feeble-minded after six months in rebel prison. Violent at times for twenty years. Did no work, thought "soul lost." Death from pneumococcus and streptococcus septicemia. Chronic diffuse nephritis.

Surely this is so, they say, for is not typhoid fever due to the bacillus typhosus and pneumonia to the pneumococcus? But it is not so. Outside of mechanical injuries there is but one disease, and the various conditions that we dignify with individual names are but manifestations of this disease.

Prostatic hypertrophy. Dr. A. M. Barrett found few changes in nerve cells, except fever changes. One area in left superior frontal gyrus showed superficial gliosis. Yet many of the actions which he felt he must perform were foolish actions. The patient died of pneumococcus septicemia during a lobar pneumonia. There were a few flecks of atheroma in the aorta.

It is only when a sufficient number of cases occur in succession to raise the virulence of the pneumococcus in this curious manner that an epidemic with high fatality develops.

Up to ten years or so ago it was generally believed that pneumonia was rare in young children. Now, however, that we make the diagnosis with a microscope, we discover that a large percentage of the cases of capillary bronchitis, broncho-pneumonia, and acute congestion of the lung in children are due to the presence of the pneumococcus.
