the person or persons convicted forfeiting all fish caught, bought, sold or 
exposed for sale, and (at the discretion of the convicting justices) all 
instruments used in the taking of such fish ; the justices having the power 
also, upon information on oath, to authorise the search of any suspected 
premises. Sundry clauses which by the Salmon Acts render certain 
modes of fishing illegal, are introduced, as well as regulations relative to 
licenses, water-bailiffs, &c. The counties of Norfolk and Suffolk, which are 
already protected by a Freshwater Fisheries Act, are exempted from the 
operation of certain clauses in the present one.—En. 
PROCEEDINGS OF SCIENTIFIC SOCIETIES. 
Linnean Socrery or Lonpon. 
February 6, 1879.—Prof. Atuman, F.R.S., President, in the chair. 
Several interesting exhibitions and remarks, chiefly on vegetable 
products, were made, the only one of zoological interest being that of 
Mr. R. Irwin Lynch, namely, parts of the bull’s-thorn acacia and imbauba 
tree, as also a couple of orchids, all exemplifying the economy of those 
plants in affording protection to and food for ants. 
A short paper, ‘On the position of the Genus Sequenzia among the 
Gasteropoda,” was read by Dr. Gwyn Jeffreys. Herein he expressed an 
opinion differing from that lately promulgated by the Rev. R. Boog Watson, 
believing that this mollusk belongs to the Solarium group rather than to 
the Trochus family, in which the latter naturalist had placed it. 
Sir John Lubbock then -read two papers “On Ants.” The first was 
devoted to an account of their anatomy, the muscular system being more 
particularly described, as elucidated by microscopical sections, &c., these 
being accompanied by an extensive series of drawings. The second paper 
was a continuation of his observations “On the Habits of Ants.” He 
observed that he had at first isolated his nests by means of water. This 
was effectual enough, but, especially in summer, the water required to be 
continually renewed. Kerner, however, had suggested that the hairs of 
plants served to prevent ants from obtaining access to the honey, and it 
accordingly occurred to him that strips of fur arranged with the points of 
the hairs downwards might answer his purpose. He had tried this, and, 
finding it successful, he thought a similar arrangement might perhaps be 
found useful in hot countries. It is generally stated that the queen ants 
alone lay eggs, but Sir John has found that in most of his nests some few 
of the workers are capable of doing so. It appears, however, that these 
eggs always produce males. In the case of bees we know that the queen is 
ed on a special kind of food. In ants it is not feasible to make observations
