the chase." " The little dog died of haemorrhage from the bladder 

 or kidneys ; but no post mortem examination was made." 



" The large dog soon began to cough up bloody phlegm, with 

 considerable fresh blood at times. I found in the phlegm one 



morning two Filariae alive, and at least six inches long My 



large dog grew so ill that I had him shot. His symptoms were 

 drowsiness, sleeping with the upper eyelids raised, and the inner 

 lining showing very red, holding his head to one side, one ear 

 drooped ; dragging of one hind leg, turning round and round 

 whenever he attempted to go anywhere ; and finally spasms, in 

 which he rolled over and over and drew his head backward. He 

 was fat and had a good appetite to the last." 



The heart which Meguin described (9) was that of a New- 

 foundland dog sent to him from China, preserved in spirit. He 

 states that the animal succumbed with every symptom of serious 

 cardiac disorder, and that before death it suffered from palpita- 

 tions and fits resembling epilepsy.

(3) Variations in the Larva of Asterina gibbosa. By E. W. 

 MacBride, B.A., Fellow of St John's College. 



The larva of Asterina gibbosa, when fully grown, but before 

 any external traces of the metamorphosis are visible, presents the 

 following features, in longitudinal, horizontal sections, viz. : there 

 is a great prseoral lobe ; the gut is a simple elongated sac devoid 

 of an anus, but with a mouth opening into it through a vertically
