This was a very powerful antiserum giving an immediate dense 

 clouding, followed by a very large precipitum, with a dilution of snake 

 serum. Moderately well-marked reactions were obtained with specimens 

 from all the sub-classes of the Reptilia, especially the Ophidia, as well 

 as with the diluted egg-albumin of the tortoise. 36 7o *^*f the Birds' 

 egg-albumins also reacted with this antiserum.
