The more serious work of the Congress was varied by visits to the Exhibition, 

 museums, excursions and receptions. At the Eoyal Museum of Natural History 

 an excellent portrait group was taken. 



Among the most important papers read may be mentioned a lecture by Dr. 

 E. Blanchard, of Paris, on Medical Entomology, dealing with the transmission of 

 malaria, yellow fever and sleeping sickness, and it may be mentioned that there 

 was a most interesting exhibit in connection with these subjects in the Exhibition. 

 Mr. Theobold, of Wye College, gave a lecture on the distribution of Stegomyia 

 fasciata, the conveyer of yellow fever. Sir Daniel Morris described the methods 

 employed by the Imperial Department of Agriculture in the West Indies to pre- 

 vent the introduction of insect pests by fumigation and quarantine. Dr. G. H. 

 Carpenter, of the Eoyal College of Science, Dublin, gave an instructive account 

 of the warble fly, Hypoderma hovis. He declared the so-called preventive washes 

 quite useless, but had not concluded his investigations.
