PSYCHE. 



dwellings from which mosquitoes could 

 be barred out, in order that the German 

 colonies of Eastern Afiica might he 

 freed from malaria, ought surely to be 

 acted upon in countries where it is not 

 only malaria that has to be contended 

 with, but also the dreadful yellow fever, 

 aptly called the "plague" in the early 

 Spanish chronicles of Apierica, from 

 its analogies with the Oriental disease 

 of that name. Why should not the 

 houses, in yellow-fever countries, be 

 provided with mosquito blinds, such as 

 are used in the United .States as a mere 

 matter of comfort, whereas here it 

 might be a question of life or death? 

 The mosquito larvae might be destroyed 

 in swamps, pools, privies, sinks, street- 

 sewers, and other stagnant waters, 

 where they are bred, by a methodical 

 use of permanganate of potassium or 

 other such substances, in order to lessen 

 the abundance of mosquitoes; but the 

 most essential point must be to prevent 

 those in.sects fr6m reaching yellow-fever 

 patients, and to secure a proper disin- 

 fection of all suspicious discharges, in 

 Older to forestall the contamination of 

 those insects. Well ventilated hospitals 

 should be built on high grounds, with 



no stagnant waters or marshes in their 

 vicinity, the doors and windows pro- 

 tected by mosquito blinds, a good sys- 

 tem of drainage and sewerage, with 

 facilities for disinfecting all suspicious 

 discharges, and for destroying such 

 mosquitoes and larvae as might lie 

 found within the building. Only the 

 upper stories should be occupied by the 

 sick, and none but vellow-fever patients, 

 and such malaria patients as are im- 

 mune against yellow-fever, should be 

 admitted. The exammation for admis- 

 sion might be carried out in a separate 

 building, and a separate department 

 devoted to suspicious cases under obser- 

 \'ation. 



Witii such hospitals at hand, and an 

 efficient hoard of health that would see 

 to the proper arrangements for patients 

 who could be left in their liomes, and 

 general sanitary improvements in and 

 around the principal cities, there can be 

 little iloubt that yellow fever might be 

 stamped out of Cuba and Porto Ribo, 

 and malaria reduced to a minimum. 

 It would then be the business of the 

 port and quarantine officers to prevent 

 the introduction of fresh germs.
