(1) Worli village is badly infested with rats, practically all M. rattus.

(2) Persistent trapping for one year appeared to reduce the rat population to approximately one quarter of the original number.

(3) Three cases of plague which occurred in the village were investigated. It is probable that these three cases all contracted the infection outside the village.

(4) In two instances there is evidence which points to infection having been introduced in the clothing or persons of people, and of this spreading in one instance to a guinea-pig, and in the other instance to rats.

page 805 note 1 During this period 465 rats were trapped alive from houses in the whole village of Sion. These included 381 M. rattus, 81 musk rats and 2 mice. Not a single M. decumanus was found.

page 805 note 2 For ease of description we have departed in the case of certain buildings requiring detailed notice from the nomenclature adopted by us during the investigation. These buildings will hereinafter be referred to by letters of the alphabet given to them in the order of the earliest event occurring in them which pointed to plague infection.
