conjunction with Gilford's screen and an apochroniatic sub-stage 

 condenser, the resultant definition being so clear and perfect that 

 personally I can feel no doubt whatever that the features depicted 

 in the figure (sketched at the microscope) truly represent the 

 real structure of the monad, which was carefully observed for 

 a sufficient time to make sure of its characteristics. The side- 

 spines, together with the flagellum flanked by them (situated at 

 the posterior extremity of the body, and not at the anterior end), 

 received particular attention in order to determine their compara- 

 tive lengths, each spine being separately brought into sharp focus. 

 It is not my intention to suggest a new species ; indeed, I con- 

 sider that the organism is probably a common and well-known 

 infusorian, whose true form and appendages have escaped previous 

 notice." 



OBITUARY. 



CHARLES STEWART, M.R.C.S., LL.D. Aberdeen, 

 F.R.S., F.L.S., F.R.M.S., 



Conservator of the Museum at the Royal College of Surgeons. 

 Died September 27th, 1907. 



Professor Stewart became a member of the Club in 1877 and 

 remained so until 1905, during part of which time he acted 

 as Vice-President. He took a great interest in the Club's 

 welfare and not infrequently attended its meetings. He wrote 

 but little; but as a lecturer or debater he was unrivalled, being 

 greatly helped by his remarkable skill in blackboard drawing. 

 His remarks were always the expression of his own experience, 

 and bore, in consequence, the impress of his personality, which 

 was charming. As Conservator of the Museum of the Royal 

 College of Surgeons he was facile princeps, well maintaining 

 the traditions of his eminent predecessors (among whom was, 

 of course, John Quekett), his Physiological series and display 

 of Adaptive Modifications in the museum testifying to his 

 genius; but at heart he was an open-air naturalist. 



By his death we lose an eminent clubman, and those who 

 knew him personally mourn also the loss of a brave and youthful 

 nature.
