 lias 'been found in about nine per cent, of all 

 human beings examined. 



Eeceritly the writer lias discovered Eug'Iena- 

 like flagellates in the rectum and intestine of 

 tadpoles. One species has many of the char- 

 acteristics of free living Euglense including 

 green chromatophores, a reservoir and a red 

 stigma. This species possesses three flagella. 

 Another species resembles Euglena spirogyra 

 and a third species is similar to Phacus pleuro- 

 nectes.

SCIENTIFIC EVENTS 

 ALEXANDER SMITH 

 The New York Section of the American 

 Chemical Society having appointed a com- 

 mittee, consisting of Professors Thomas B. 

 Freas, Ralph H. McKee and James Kendall, 

 chairman, to draw up resolutions in memory 



of the late Professor Smith, the following reso- 

 lutions were prepared and approved by the 

 section on October 6: 



Whereas, By the death of Alexander Smith at 

 Edinburgh on September 8, 1922, the American 

 Chemical Society has been deprived of a past 

 president and 'the New York Section has lost one 

 of its most highly esteemed members: 



And whereas. Although the work of Alexander 

 Smith as a teacher, as an administrator, and as 

 an investigator in chemistry survives as an en- 

 during monument to his name, yet it is none the 

 less our privilege to pui; on record in the minutes 

 of the section our sincere 'appreciation of his out- 

 standing scientific genius and of his rare per- 

 sonal integrity and charm; 



Be it therefore resolved. That the New York 

 Section of the American Chemical Society express 

 its profound regret at the passing of this distin- 

 guished leader in chemistry, who by his labors 

 has added luster to science both in the land of his 

 birth and in the land of his adoption; 



And be it further resolved, That copies of this 

 memorandum be forwarded to his widow and to 

 his sister, with the respectful sympathy of the 

 section. 



THE TOTAL SOLAR ECLIPSE OF 

 SEPTEMBER 21 



De. a. C. D. Ceommelin, writing in Nature, 

 says that the failure of the Christmas Island 

 eclipse expedition is a great astronomical dis- 

 appointment. Messrs. Jones and Melotte have 

 devoted ten months or more to it, and hoped to 

 secure useful photometric results for eonneetng 

 the northern and southern stellar magnitude 

 scales in addition to the eclipse work. The 

 climate, however, proved unexpectedly unfavor- 

 able, and practically nothing could be done. 



On the other hand, the conditions appear to 

 have been ideal right across Australia, and en- 

 thusiastic reports have come from WoUal (West 

 Coast), Cordillo Downs (center) and Goondi- 

 windi and Stanthorpe (Queensland). The 

 Einstein problem was studied at Wollal by the 

 Lick Observatory party under Professor Camp- 

 bell, and that from Toronto under Professor 

 Chant. Mr. Evershed also finally selected this 

 station in preference to the Maldives, and is 

 believed to have undertaken the same investiga- 

 tion, in addition, doubtless, to spectroscopic 

 work. Professor Dodwell, the government as-
