the rapid drawing uj) of the anal claspers to the prolegs, and so 

 niakinj^ the body into a loop. 



Films taken of aquatic insects such as tlie Common Water- 

 Beetle (Di/tiscus), AV'^aler-Sforpion [Nepa cinerea), and the AVater- 

 Bojitmau (Notonecta), all show the characteristic movement of the 

 limbs. 



Perhaps the most interesting film is that showing a Butterfly 

 emerging from its chrysalis, as it first bursts opeu, gradually 

 withdraws its legs, antennae, tongue, and body, followed by tlie 

 \\ iiigs, catches hold with its claws as the wings fall into position, 

 and then, swayed to and fro by the \\ ind, mysteriously develops 

 until the wings attain their full 8i7,e. 



Passing from insects, an interesting fdin of two Lizards engaged 

 in a fierce struggle for the possession of a meal-worm, shows how 

 they can plant their claws and throw each other over in the most 

 approved fashion of wrestling. 



The film of swimming Sticklebacks was produced by Mr. New- 

 luan ; and the last film showed a tongueless Frog from the Cape, 

 catching and sw^allovving a worm, during which operation it makes 

 a most comical use oL" its front legs and claws for pushing the 

 worm into its mouth. 



I feel that attention ought to be called to Mr. Newman's inven- 

 tion of a safety trough, which is inserted between the illuminant 

 and film, which, being filled M'ith water, prevents the film from 

 becoming dangerously heated, so that it is possible to stop the 

 apparatus at any point, when it is necessary to explain any special 

 feature.
