The water-free flesh contains (including bones) 21.7 percent of mineral matter. _Composition of the Mineral Matter._-- Lime, 8.67 percent Phosphoric acid, 7.78 „ Silicic acid, 1.33 „ Potash, 1.54 „ Soda, 1.02 „ Magnesia, 0.67 „ Chlorin, 0.69 „ ----- Total, 21.70 „ =Mullet.=--The mullet belongs to the Mugilidæ, an important family of fishes in which there are several genera and species. The mullet is not particular about its food but is in the habit of swallowing large quantities of mud, or rather partially swallowing it and separating the refuse and most obnoxious particles by means of the gills. The common mullet or striped mullet (_Mugil cephalus_) is a widely distributed species. This fish is common along the Atlantic coast and in Hawaii, usually traveling in large schools, and is most abundant in the shallow waters of the coast. It sometimes reaches a length of two feet and is an important food fish. The mullet is very abundant on the Florida coasts. While the mullet may be regarded as a scavenger, living principally on mud, it does not eat any other species of fish, but is itself eaten by nearly all fishes that can gain access to it. _Composition of the Mullet._-- FRESH. DRY. Water, 74.87 percent Protein, 19.32 „ 77.50 percent Fat, 4.64 „ 18.45 „ Ash, 1.17 „ 4.66 „ =Muskallunge.=--A very noted member of this family is the muskallunge (_Esox masquinongy_). It is a native of the Great Lakes and is especially found in the upper St. Lawrence. It is not a very abundant fish, but is highly prized from the angler’s point of view. It is of very great size, having been found as long as 8 feet and weighing over 100 pounds. Two other species of muskallunge are known, one (_Esox ohiensis_ or the Chautauqua muskallunge) in the Ohio river basin, particularly in Lake Chautauqua, where it has been artificially propagated with great success, and the unspotted muskallunge (_Esox immaculatus_), which occurs sparingly in certain small lakes of northern Wisconsin and Minnesota. _Composition of the Muskallunge._-- FRESH. DRY. Water, 76.26 percent Protein, 19.63 „ 84.87 percent Fat, 2.54 „ 10.70 „ Ash, 1.57 „ 6.63 „ The flesh of the muskallunge, as is seen, contains about four times as much fat as that of the pickerel, and forms a ration which is not so unbalanced as that of the pickerel itself.
