The other rooms in the house are care fully gone over. Each room is tightly sealed by pasting papers over the cracks, just as is done In the n,vsse use GI 1t then burned at the rate of a pound for every 1000 cubic feet. This makes very dense fumes and will kill most of the mosquitoes. but as a great many would revive if given flesh air, the room is opened at the end of two hours. and the mosquitoes swept up and killed. Every room in the house Is gone over in this way and all the contiguous houses treated in the same manner. On an average. 15O pounds pyrethrum powder are used In mosquito killing, for each case. When the case is ended the rooms occupied by the patient are gone over in the same way. The clothing is not disturbed or any other disinfectant used. The patleht is ouarantined to a certain extent, only allowed in the screened area, ana guard is placed here to see that proper precautions are observed, in regard to keeping the door closed: Ihe ailpowing dnpartmentth the i physicians to designats four or five immunes who can Vislt the patient, and very little restriction is placed upon the taking out oare or haine aan taken to shake those in which mos quitoes might be conveyed; a
 This system has succeeded beyond our fondest expectations. We seem. without fail, to have destroyed prac- tically all the infected mosquitoes. in every case, until gradually all infected mos0uitoes in Havana have been Killed or died a natural death.
 Free of Yellow Fever.
 Since September 2S we have not nad single case of yellow fever, ana believe that at the present time thsre Is not an infected mosquito left in the city, and that Havana will not have any more yellow fever until it is intro duced from neighboring towns which become infected during the summer;
 a system system of of inspection by employing Inspectors in the neighboring m Infected , ing from these towns-men generaliy who were natives and knew everybody there-who reported every non-immuhhe .ihe e had been in Cuba less than five years or had not had yellow fever, was con sidered immune.
 Tn the two or three towns infected, during the period of infection we had l,275 non-immunes come into the city and from these 1,275 non-immunes we got twenty-seven cases of fever No case of fever was known to have es- capped the inspectors. The non-im- munes reported by the inspector were seen on the third and sixth days. If second inspection. at the end of the sixth day, they were dropped. Of course, the large proportion of these 1,200 non-immunes merely came lnto the city for a day and returned to their homes at the end of the day. No re- strictions whatever were placed upon the introduction of fabrics and supplies of any kind. The results have been very satisfactory. This, as far as my knowledge goes. is the first time that this system of inspection has ever been the direct outcome of the mosquito theory We were convinced that we had nothing to fear from any belong ings of the patient, and all that we one of these towns being taken sick in Havana and poisoning our ste gomyia mosquitoes. The immunes, teen-twentieths @ of the population. were allowed to come and go freely, and we believed we could prevent the non-immunes doing any harm by see ing each of them On the third and sixth
 While some twenty-seven of these non-immunes had yellow, fever in the the mosquitoes infected by them.
 The results of our mosquito work. we can point out with considerable degree of accuracy, which is not the mosquito work since ours None, l be- lieve, had tried before we commenced. refer not only to tho figures given with regard to the decrease in ratio, but the actual deaths caused by mos quito bore disease. can be compared before and after our mosquito work. In yellow fever we have been entirely successful The average number of deaths from this disease for the past thirty years has been 7O6: for the year preceding our yellow fever work, we had BIO deaths; for the year of our yellow fever work, only IS deaths. and 1S of these occurred before the work commenced.
 For malaria, while the figures are not so striking, 1t seems to me that the results point just as positively to- wards the mosquito killing being the beneficial agent For the past eleven years we had an average number of 5l3 deaths: for the year 1900, before the mosquito work began. we had S44 deaths, and the year 1901. the year of our mosquito work, 151 deaths.
 The whole work of the army, in connection with yellow fever, has been unique, as far as I know, In all the history of medicine. Dr. Ftnlay's the ory was taken up by Major Reed and the Army Board, expertmented upon by means of human subjects. and the mat ter proven. as no other theory in medi- cine has ever been proved, in the course of q single year.
