The low-necked, sleeveless dresses worn by ladies in the evening must, we can well understand, be very temptingly cool wear in the climates with which we are dealing, but are obviously extremely dangerous, as they leave a large surface of the person exposed at the very time when mosquitoes are most active. A dress covering these parts should be therefore substituted, which, however, may safely be made of the lightest materials, provided that it be so puffed or otherwise “confectioned” as to make it difficult for a mosquito to get within reach of the skin. Mosquitoes are always fond of collecting under tables, as they are there sheltered from the glare of the lamps, and on this account it is advisable for men to wear straps to their trousers when dressing for dinner; and though the plan is a very old-fashioned one, I have some hope that the suggestion may meet the approval of our better halves, as, whatever its real object, the adoption of the plan certainly gives the wearer the air of having sacrificed comfort to appearances. There would, however, be no need of modifying costume for indoor wear in any way were houses properly protected against the entrance of mosquitoes by means of suitably planned wire-gauze protection to all openings. The plan in question was devised by Professor A. Celli, the Principal of the Institute of Hygiene in the University of Rome, and in Italy at least has long passed its experimental stage; though, owing probably to the small number of Englishmen who are familiar with the Italian language, it appears to be practically ignored even by our specialists on the subject. Within a few miles of the great city of Rome there are large areas where malaria, far more virulent than the type of disease we usually meet with in India, is so rife that, during the malarious months, the country is practically deserted by all but a few necessary railway officials and caretakers. Amongst the former the mortality and invaliding used to be so heavy that the working of the lines was a matter of the greatest difficulty. The majority of the peasantry, being only temporary inhabitants, live in grass huts not a whit in advance of those of the savages of Central Africa, and from the migratory nature of their employment, are among the most ignorant and backward of the Italian populace, and so about the last people likely to lend themselves to the adoption of any “new-fangled” custom. As a matter of fact, however, the object lesson of the advantages of the system have been so obvious that, after the first year, there has been no difficulty in securing the eager co-operation of the simple railway men and scarce civilised farm hands. As the system is necessarily being very gradually introduced, there are plenty of unprotected houses for comparison, and after personally conversing with the inhabitants, the writer found that all who had enjoyed the benefits of the plan were convinced of its efficacy.
