with five or six inches of straw attached to each ear, weighed' four pounds and a 
half. The clear grain weighed about 20^ ounces avoirdupois. 
“ In order to institute a comparison between this and English Wheat, a 
measure of the best English "Wheat, lately received from Whitehaven, and an 
equal measure of the Victoria Wheat, were weighed, and their relation to each 
other was found to be as 131 to 108; consequently, supposing the English Wheat 
to weigh 60 lbs. per bushel (which is the usual weight), a bushel of Victoria 
Wheat would weigh 49^ lbs.; hence it appears that the produce of an acre of 
the Victoria Wheat would, under similar circumstances, amount, as nearly as 
possible, to 5^ Winchester bushels. The grain is small, hard, and shrivelled, and 
the only use to which it appears to be applicable, beside the feeding of stock, is 
the manufacture of maccaroni and vermicelli. For the purpose of ascertaining 
the truth of this supposition, equal quantities of flour, of the Victoria and English 
Wheat, were subjected to the necessary operation for separating the gluten, which 
was at once perceived to be extremely abundant in the former sample, and, on 
being weighed, was found to exceed that of the English Wheat, in the proportion 
of 2.5 to 1. The bran also is very abundant, and exceeds that of the English 
Wheat in about the same proportion as the gluten. Samples of the ears, grain, 
flour, and bran, of the Victoria Wheat, are forwarded with these memoranda for 
inspection and examination. A sample of English Wheat is also inclosed for the 
purpose of affording a comparison.”

AN OUTLINE OF THE COMPARATIVE STRUCTURE OF THE 
ORGANS OF LOCOMOTION IN RADIATED ANIMALS. 
By Thomas Wright, M.R.C.S. 
The true Radiata comprises those primary types of the animal kingdom, whose 
essential characters consist, in having their component parts disposed around a 
central body, and their nervous system in form of a simple gangliated cord 
encircling the entrance to the digestive organs. Some are provided with simple 
eyes, in others they are absent. The skeleton presents many phases of develop¬ 
ment, and in the higher classes is extremely complicated; in them we discover 
the first traces of a fibrous muscular system. The digestive organs vary consider¬ 
ably in the different organs of each class. In many we observe a system of 
vessels ramified through the body, in which the nutritive fluid slowly moves; 
respiration is performed either by the introduction of water into the interior of
