Excerpt from The Journal of Hygiene, 1917-18, Vol. 16 A summary of the results obtained in this series of experiments shows in a conclusive manner that pneumonic-plague-infected marmots can readily transmit the infection through the respiratory passages as in the case of man.

Close contact and moist surroundings seem to favour the rapid spread of infection from animal to animal. Out of seven marmots inoculated by inhalation, five (71 died after 4-6 days with acute pneumonic plague and septicaemia. Nine contacts placed with infected animals after periods varying from 1 - 4 days showed a mortality of 77 These seven marmots died after 4 - 6 days' contact. Here also, as in the preceding series, was noted a remarkably short incubation period, with marked infectivity on the part of the sprayed animals.
