Palinurus vulgaris, have been secured in perfect condition 

 for our Museum collection. The first is 8 T 5 a inches long, 

 and the second, cast twelve months afterwards, is exactly 

 half an inch longer. As there is good reason to believe 

 that growth is slower as age advances, it may be assumed

 flat-fish tank has lost but two of its inhabitants during 

 the year.

 to Port Erin, many of whom pay repeated visits during 

 the summer, and watch the movements of the inhabitants 

 of the tanks with the keenest interest. There has been a 

 great demand for copies of the " Guide to the Aquarium " 

 this season, and many of the readers ask for further 

 information, which we shall endeavour to supply in the 

 new edition now called for. We are indebted to one of 

 our visitors, Mr. George Briddon, of Chesterfield, for six 

 Manx coins, in excellent preservation, as an addition to 

 the small collection of Manx antiquities exhibited in one 

 of the cases of the Museum gallery.
