with me, but found that my somewhat halting French was sufficient, 

 and explained to a deeply interested group the habits of the wasp in 

 the southern United States and as much of its life history as we 

 knew. I think that was my first visit to the Pasteur Institute, and at 

 that time I had the pleasure of meeting Metschnikoff and especially 

 A. Laveran, the discoverer of the causative organism of malaria. 



Laveran was at that time a scholarly looking man in his late sixties 

 (I should say), with a full but well cared for white beard. We talked 

 at some length on two or more occasions. On one of them he asked 

 me whether we had some one in Washington who could identify bit- 

 ing Diptera from Indo China. I replied that we had, but said, " Why 

 don't you send them across the Channel to Major Austen, who has 

 recently published an admirable work on the tsetse flies?" Laveran 

 pointed to the book on his shelf, shrugged his shoulders, and changed 

 the subject. I did not quite understand, but imagined that it might 

 have been one way of saying without words something about " La 

 perfide Albion." But I did him an injustice, as I discovered a week 

 later. Then I happened to be in INTajor Austen's room in the Brit- 

 ish Museum, and I told him the story. " Oh," he said, " Doctor 

 Laveran ! There is a box I had from him more than a year ago, and 

 I have not had time to open it ! " Later Laveran sent his French 

 Indies flies to Washington and they were studied by Coc^uillett. 



I have had very interesting talks with Celli, Grassi, Tiraboschi, 

 and Negri in Rome, and knew A. Caccini after he came to the United 

 States, but I will tell my story about these men in later paragraphs. 

 I shall never forget a two hours' journey from the Campagna to 

 Rome over the Appian Way in an ox-cart with Celli, Doctor Vail of 

 Philadelphia, and Doctor Ivantcheff of Bulgaria, a journey which 

 Celli called " our triumphant entry into Rome." This was in 1910, and 

 the Appian Way and the ox-cart did not suggest a modern cement 

 road and a six-cylinder automol)ile — far from it. 



Df, Erich Martini, of the Hamburg Tropical Disease Laboratory, 

 in 1 9 13 spent part of the summer in Washington studying mosqui- 

 toes and other disease-bearing insects. He was a very able and very 

 interesting young man. During the four years of the war he was 

 very busy over there, Init since the war has resumed his investiga- 

 tion work, has traveled in southeastern Europe, and has written many 

 good papers. I ran across him one day in 1927 in Major Austen's 

 office at the British Museum. Later I met him and talked with him at 

 the International Congress of Zoology in Budapest in September, 

 1927; and, fortunately, in August, 1928, he was able to visit the 

 United States again on the occasion of the Fourth International Con-
