had, therefore, been in the harbor, at the time of the death, for 

 a period of twenty-four hours. At the medical inspection of 

 the vessel made at the time of its arrival, no illness was detected. 

 The investigation showed that the victim had been on deck on 

 the night of April 5, apparently in good health. The next morn- 

 ing, at 6 o'clock, he was found dead in his bunk. The necropsy 

 and subsequent biological findings showed that death had been 

 due to pneumonic plague. On April 7, the steamer Loongsang 

 arrived in Manila from Hongkong, and the captain reported 

 that a death had occurred the day previous in a Chinese member 

 of the crew. Upon an investigation of this case, the captain 

 stated that the man was, apparently, in good health, but that 

 while hauling on a rope he fell over in an apparent faint, was 

 placed in a chair, and in the course of a few hours was dead. 

 The necropsy and animal inoculation showed that he had died 

 of pneumonic plague. From this time forward, the tempera- 

 tures of all the crews and passengers on incoming vessels were 

 taken as a further safeguard. 



On the arrival of the steamer Taisang at the Mariveles Quar- 

 antine Station, about 6.30 a. m., April 30, 1912, the entire person- 

 nel was carefully examined and found free from sickness of a 

 suspicious nature, nor were there any elevations of temperature. 

 Seventy-three persons were detained. At the afternoon inspec- 

 tion, a passenger, Co Sing, aged 51 years, Chinese, was found to 

 have a temperature of 39° C. and pulse of 100. He was im- 

 mediately placed in the hospital, but protested vehemently that 

 he was not sick. The man was carefully watched from the 

 first. There was a slight cough; physical examination of the 

 chest revealed only a few rales. Smears made of the sputum 

 and stained for plague were negative. On the fifth day the fever 

 still continued, but the patient still insisted that he was not ill, 

 and demanded to be released from the hospital. On this day 

 the expectoration was blood-stained, but no suspicious organisms 

 were noted in the smears, nor could any physical signs of 

 pneumonia be detected. No enlarged glands could be palpated 

 anywhere. On the morning of the seventh day the temperature 

 and pulse dropped, and the general condition was distinctly 

 worse. The patient now admitted that he felt ill. Several 

 hours later the patient flinched when pressure was made in the 

 right axilla, and slight lymphatic enlargement was made out. 

 By the evening of this day the bubo in the axilla had increased 

 markedly in size, the outlines of the swelling being, approxi- 

 mately, 3 by 7 centimeters. Glands now became palpable in 

 other portions of the body, particularly those in the cervical
