good results with orthochromatic plates with the tele- 

 photo lens, as I have found them always too little sensitive 

 to white light for instantaneous work. Latterly there has 

 been produced a new kind of panchromatic plate which 

 only needs an exposure of one-fiftieth part of a second, and 

 I would stronglv recommend its use for the photographing

of animals for this reason. 



In the animal pictures ot the Munich painter Ztigel, 

 we see admirably rendered all the many shades of colouring 

 we note, under different conditions, close at hand or far 

 away, when we have the actual wild life before our eyes. 

 There we note that the upper part of the animal's body 

 often reflects so strongly the cold blue of the sky that 

 its own colouring is, as it were, cancelled, or at least very 

 greatly modified. We note, too, that an animal in reality 

 reddish-brown in colour becomes violet owing to the blue 

 in the atmosphere. Refinements of form and hue are lost 

 in the glare of the sun, and only the stronger outlines 

 and more pronounced colours assert themselves. Some- 

 times the sun's rays, reflected trom the animals' skins, 

 produce the effect of glowing patches ot light, sometimes 

 they are absorbed ; sometimes the animals look quite black, 

 sometimes absolutely white. Photographs of animals 

 taken under such conditions do not, of course, give a good 

 idea of the normal colouring of the animals. The success 

 ot a photograph depends, therefore, very largely upon the 

 nature of the light. 



For an effective picture you need to have a group 

 ot animals either standing still or in motion, and this you 

 can very seldom get at close quarters, though now and
