the attcin})t, bearing in luind that, in examination lor ourselves 

 or disphiy for others, it is always necessary to consider well 

 what the prominent features are which we ought to see or sliow, 

 and that we should never rest satisfied until we can render these 

 perfectly clear and bright. 



I do not know whether the electric light, as recently intro- 

 duced for the illumination of microscopic objects, will be brought 

 within our reach, or work any changes for the better if it 

 should ; bi;t I am qiiite siire that the apparatus already to 

 hand is capable of grand achievements if only used in the best 

 way, and my hope is that these notes may help to stimulate 

 others in their endeavours to accomplish this end.* 



NOTE. 



[Read at a previous Meeting. J 



Volrox ijlohator. — h it a Hollnic Sphere.' 



The question asked at the heading of this note is answered 

 in the affirmative by so many competent observers that I should 

 hesitate in submitting an opposite reply, did I not feel sure that 

 it is easy for microscopical students to demonstrate for them- 

 selves the certainty that these charming little globes are not 

 hollow, but solid. 



Probably no microscopic organism has attracted, or de- 

 serves, more attention, or has been more fully discussed than 

 Volvux globator. Each interesting feature in its structure and 

 life-history, as far as they have been recognised, has again and 

 again been studied, a variety of views upon most of its details 

 being the result, and strange it seems that with so much careful 

 observation, and so many often contested points, the idea of its 

 being hollow has passed as so self-evident as scarcely to have 

 been challenged. 



* Mr. Levick here remarked that he had mentioned one piece of 



apparatus which the members might not be able to purchase or raake for 

 themselves, and that was the fine metallic net. He had therefore brought 

 a few. which he had much pleasure in placing at their disposal. — Ed.
