fins, which will now retain their natural position. Common copal 

 varnish, diluted with turpentine, is recommended as the best. The 

 cornea now becomes hard, transparent, and continuous with the sur- 

 rounding skin : the wadding may be removed through the back of the 

 sclerotic, and a bit of foil introduced in its place, of the colour 

 originally possessed by the animal, in many of which we know the 

 tapetum is very brilhant. The author noticed the difficulties which 

 attach to this process in fishes with small scales, and described the 

 methods by which they were overcome. 



Mr. R. Patterson exhibited drawings made from living specimens of 

 a species of Ciliograde, taken in July last at Bangor, County Down. 

 Its occurrence on the Irish coast had first been announced in a note 

 a])pended to his paper on the Cydippe pomiformis, published in the 

 Transactions of the Irish Academy. This animal he had referred, 

 though with some doubt, to the genus Bolina, of Mertens, and named 

 it provisionally Bolina Hihernica. He mentioned some particulars 

 relative to its appearance, movements, frangibility, and luminosity.
