��effects of contrast as of aenantion. Take a card, white OR one side, ntid halt green and balf white on the otlier, with a dot in the eeutre of each side, to hold the attention. Look sleadily at the grceii-arid- white sMe for a minnte, then turn llio card, and the half corresponding to the green will have a red lint, and the other half will have a complementary green tint. The consecutive red image has deyeloped, by induction, the green sensation In a part of the eye which had leen iinpreBge<l only by whii*. The name results arc obtained if Uie subject be hjpnotixed. The experiment will tail if the subject is blind to the suggested color. If a subject is blind to a cenaJu color, a peculiar case results. On giving him the hallucination of green, the sensation of red cannot be induced; but in giving the hallucination of red, which he can sec, the iniluced sensation of green (to which lie is blind} is produced.
The production of consecutive Images is a normal phenomenon: 80, in all hallucinations which last a cer- tain time, a consecutive image follows. If one causes a patient in a liypnoiized state U) look at a square of wliite paper with a point In the centre, au^ests that the square is red, and then suddenly presents a sec- ond similar square, the subject will say that the point Is snrronudai by a colored square, and the color will always be the coniplementary of the one suggested. This complementary color is the negative image left bjthe hallucination. It lasts only a short time, then iMComes effaced. That similar phenomena are ob- served In the normal condition, may be proved by the following: if. with the eyes shut, we keep the Image of a bright color in our mind a long lime, then open Ibem suddenly, looking upon a white surface, we will then see for a short time the Image we were con teui plating, but of a complementary color.
The following most curious experiment upon the mixture of imaginary colors helps to prove the same thing. Place two squares of differently colored paper at some distance upon a table; then place before the eye a plate of glass Inclined in such a mniiner that the whole of one card can be seen directly, and at the same time a reflected image of the second. One can very readily cause Ihe two papers to superpose, and become mixed. If we show a hypnotised patient the ■ame thing, substituting blank cards, and suggesting colors for each canl, they will-appear mixed to bim in the same manner. The necessary conclusion from this seems to be, that hallucination of a color Is a sug- gested sensation, having the same cerebral seat as the real sensation.
��Thk fourth annual report of theshell-Bsh commle- sioners of the state of Connecticut was recently issued, and contains. In conclae form, much useful Information. In lis record of beneSts accrued to the stale by its system of ownership and moderate taxa- tion of iiysier-plantitig grounds, it offers great en- oourageroeni to those who would institute in each itate systeulutic business methods in connection with

of the most ini|>orlnni ot all our fishery We have before referred to the system adopted by the coinmissioii in mapping and deter- mining permanent bounds for the natural beds and ground available for planting. The aun'ey of the natural beds, which are open to all oystennen under certain restrictions , has been completed. They com- prise 5,805 acres. The total area of planting-grounds, designated for occupancy by the comnilaalon since its organization, is 45,<)4tt acres, which have netied to the state $40,o()U. Adding to this the area pre- ■ vlouslj designated by the seaside towns, and we f have over 19,018 acres now under the control of in- dividuals, of whldi 14,0110 acres are under culU' Uon.
The total number of lax-payiug culUvatora in l88t I was 3gn, of whom IS own each five acres or between five and twenty acres each, and i twenty acres or more each. The amount of led, averaging ten cents per acre, was about $0,600, I of which less than $50 are delinquent. This is tri-^ I fling in comparison with the locai taxation of grounds T under town jurisdiction. Eleven hundred acres of ^ grounds in the state of Rhode Island pay a rent of a hundred dollara per acre to that state. The 1 Connecticut commission has not valued grounds (or I taxation in excess of fifty dollars per acre, thon{^ J lands have been reported sold during the year at from 1 two to six times that amount. It Is obvious, there- ] fore, that the encouragement given by the slate ti those employed In this business la very great. Tha I business Is steadily growing. There are already over I three hundred sailing-vessels and forty steamers J employed, the latter wjlh an aggregate capacity ot I 36,720 bushels; and several more steamers are being | constructed. The first steamer was employed 1 than ten years ago.
There has been a very considerable increase In i sale of seed oysters and stock to neighboring statM, I and also iu the exportation to Oreat Britain. Oys- I ters for export are packed In barrels containing 990 | four- year-olds, or 1,51X1 three-year-olds, the deep va1r« J down and pressed very solid. One flmi, exporUngl 10,000 barrels a year, has never lost a bushel by long] passage, ba<l weather, or other causes. Many arefl shipped to California also.

The chief Injury sustained in the business is froinj star-fiBhea, whichdealroytheyoungoysters. It is est! mated that over fifty thousand bushels of stars werft'S destroyed last year.
