Huxley Memorial.—Since the first meeting of the General Committee on November 27, which was fully reported by the Press, two meetings of the Executive Committee have been held.

At the first of these, at which Lord Shand accepted the office of Chairman, it was reported that a number of foreigners of eminence had expressed a wish to be associated with the proposal to commemorate Mr. Huxley's distinguished services to humanity. It was resolved, in the first instance, to invite subscriptions from the members of the General Committee.

At the second meeting, held on December 18, it was reported that the subscriptions, which at the General Meeting had amounted to £557, had been increased to about £1,400, and it was resolved that a wider appeal for subscriptions should now be made to the friends and admirers of Mr. Huxley amongst the general public. The sum subscribed now exceeds £1,500.

The Honorary Secretary stated that in America Committees were in the course of being formed to promote the realization of an adequate fund.

The Committee resolved to communicate, by means of a sub-committee of their number, with Mr. Onslow Ford, R. A., who had the advantage of being well acquainted with Mr. Huxley, in reference to the statue, which it is proposed should be erected beside those of Darwin and Owen in the Natural History Museum, South Kensington.

The extent to which the Committee may be able to carry out the other intended objects of founding exhibitions, scholarships, and medals for biological research and lectureships, and possibly in assisting the republication of Mr. Huxley's scientific works, will, of course, depend on the subscriptions which may now be received.

Meehans' Monthly is a magazine for the lovers of gardening; and covers the whole field of general intelligence in so far as it may have the remotest bearing on the chief topics it sets out to advance. For instance, a beautiful Prang colored plate of some wild flower is given every month, with a description which illustrates the whole ground of classical history that has any bearing on the topic. Information on the most diversified topics abound. Corn from Indian mounds will not grow-swamps that are real swamps are among the healthiest of localities. There is no sickness in the great dismal swamp of Virginia. Elderberry root is found to be a deadly poison. Foul water is pronounced to be a self.purifier, because bacteria eat out vegetable matter and then die of starvation. The hickory and the chestnut are proven cousin-Germans. Weeds are useful, by forcing the cultivator to work to aerate the soil. Illustrations of a curious maze, formed of yew hedges at Hampton Court, pruning and keeping trees from insects, chrysanthemum culture, and practical information on fruits and flowers are among the topics treated. Sample copies may be had of the publishers, Thomas Meehan & Sons, Germantown, Philadelphia.

In the January Monist, of importance to students of evolution will be the article on Germinal Selection, by the famous German biologist, Prof. August Weismann, of Freiburg. In the theory of germinal selection, Prof. Weismann propounds a doctrine which rounds off and perfects, as he claims, the theories of Darwin and Wallace, and which consists essentially in applying the principle of the struggle for life to the minutest parts of organization, viz., to the germinal and determin. ant particles generally. Weismann's article is a complete summary of the present status of the discussions in evolutionary theory, and will itself doubtless constitute one of the most important recent acquisitions to biological science.

Abnormal pleasures and pains are treated by Prof. Th. Ribot, who applies to their explanation the pathological method, using diseases as a means of analysis. His results as regards the pleasure which some people take in pain are highly interesting.

The fourth annual meeting of University Extension and other students will be held in the four weeks beginning July 6, 1896, in the buildings of the University of Pennsylvania. The Summer Meeting combines the advantages of an ordinary summer school with the cooperative feature which distinguishes conventions, or associations, in which there are representatives of many universities and colleges.

THE BEARING OF THE ORIGIN AND DIFFERENTIATION OF THE SEX CELLS IN CYMATOGASTER ON THE IDEA OF THE CONTINUITY OF

THE GERM PLASM.

CARL H. EIGENMANN.

At the meeting of the American Microscopical Society last August I read a paper on the Evolution of Sex in Cymatogaster, of which the present paper is a part. It is not, and was not intended as a full discussion of heredity, but contains observations and conclusions forced upon me while tracing the sex cells from one generation to the next in Cymatogaster aggregatus Gibbons, one of the viviparous perches of California.

Since writing it, I have received from Dr. Minot his article “ Ueber die Vererbung und Verjüngung,” which is just being republished in the NATURALIST. I have thought best to present my results as read at the Ithaca meeting, with a note written after the receipt of Dr. Minot’s article, although the details of the observations on which the conclusions are based may not appear for some time.
