productive organs, development of the wings and legs of the 

 moths, and the MaliMghian tubules which were named after 

 liim. Now read about the interesting personality of the man! 

 Reaumur was perhaps the greatest entomologist, and as an 

 observer cannot be excelled, even today, except possibly Fabre, 

 for his observations on the habits of insects, as described in the 

 six volumes, Memoires pour Servir a I'histoire des Insectes, 

 1734-1742. Reaumur was largely occupied in the industrial 

 arts and general i)hysics and other lines. He invented the 

 thermometer which bears his name. 



Of greatest value, the lives of these men teach what two of 

 our great Californian scientists — Dr. George E. Hale and Dr. 

 AVm. PL Ritter — call and urge, the amateur spirit in science. 

 Dr. Ritter defines it thus: "A spontaneous, perennial curi- 

 osity; a wide-awakeness of perception; an openness of mind; 

 and a nimbleness of imagination, as toucliing all sorts of 

 objects and processes and incidents in one's surroundings." 

 This, as he goes on to show, does not necessarily beget sujier- 

 ficiality, as many present day biologists believe, but is a very 

 useful quality to cultivate and overthrow the current profes- 

 sionalism in science which is apparent especially in academic 

 circles. The same idea is expressed in Dr. Jordan's essay 

 already quoted from: "And my message in its fashion shall 

 he an appeal to enthusiasm in things of life, a call to do things 

 Itecause we love them, to love things because we do them, to 

 keep the eyes open, the heart warm and the pulses swift as we 

 move across the field of life." F. Grinnell, Jr.
