the flower of fishes. It measures, I find, 14 inches 

 in length; in girth 7 J. It weighs 17 ounces. It 

 has 10 spines in the pectoral fin, 23 in the dorsal, 

 16 in the ventral, 14 in the anal, and 18 in the

HAL. — Now for its anatomy. Its stomach is very 

 thick, not unlike that of a charr or gillaroo trout, and 

 contains flies, gravel, and larvse, with their cases. 

 The liver and bowels do not differ much from those 

 of a trout ; and the ovaria or roe, with eggs as large 

 as mustard seed, are on each side the air bladder. 

 Though a thicker fish, the grayling does not weigh 

 much more than the trout in proportion to Ins length : 

 the greater breadth of back is compensated by the 

 more rapid tapering of tail, and a trout in very high 

 season will sometimes equal in weight a grayling of 

 the same length. The ova in tins fish, and in the 

 species generally, are very small at this time of the 

 year; but in the beginning of April, the season of

 ova of the trout — of the size of peppercorns. But I 

 see, Poietes, your rod is in order, and there are many 

 fish rising in this deep pool, some of winch are large 

 grayling. The blue dun is on in quantity, and we
