earlier stages are rapidly passed and practically no change takes place during 

 the winter. The formation of the amnion shows a distinct posterior amniotic 

 canal similar to that of chelonians. A parietal eye rises distinct from the 

 epiphysis and the pineal gland is probably represented by a mass of convoluted 

 tubules lying in front of the parietal eye. Lacerta and Anguis have been 

 considered by Beraneck to show a similar independence of this eye.

peral fever. Caselli's experiments were made on rabbits and he divides them 

 into four classes : 



1. Effect of the introduction into the empty uterus, whose walls have been 

 injured, of the streptococcus erysipelatis. 



2. Effect of the introduction into the pregnant uterus, whose walls have been 

 injured, of the streptococcus erysipelatis. 



3. Effects of tampons infected with streptococci when introduced into the 

 injured vagina of pregnant rabbits. 



4. Effect of infected tampons on the norrhal vagina of pregnant rabbits. 



Of the animals experimented on in the first series all died in from one to 

 three days. Streptococcus infection was established in every case through 

 bacteriological examination of sections prepared from organs and tissues taken
