DISCUSSION AND CORRESPONDENCE NATURAL AREAS AND BIOLOGICAL SCIENCE

WITH the increasing activities in biological science there has been a correspondingly increased demand for the preservation of areas on which the fauna and flora may be found undisturbed by outside agencies. Workers in the various lines of ecology and genetics are particularly interested in these natural areas; the Ecological Society, several State Academies of Science, and other scientific organizations, are urging the reservation of areas suitable for study. Laboratory experiments under controlled conditions, however essential, can not replace field observation. In fact, the greater the amount of laboratory experimentation, the greater the need of natural areas— for laboratory work and field studies must go hand in hand and supplement each other; neither is sufficient unto itself.

The largest of our natural areas are in the National Parks and National Monuments. Efforts to secure the reservation of additional lands would fail of their purpose if, at the same time, the National Parks were not kept intact.

With the growing development of the country, the pressure upon the National Parks is constantly increasing. There have been a number of attempts recently to open these parks to some form or other of commercial use. The latest dangers are: First, the inclusion of the parks in the Water Power Bill, thus permitting the commission to grant permits for constructing in the National Parks and National Monuments, reservoirs, irrigation ditches, power plants and power lines; Second, the Smith bill, H.R. 12, 466, turning over 8,000 acres in one of the most beautiful parts of the Yellowstone Park to Idaho irrigation interests; and third, an attempt by the city of Los Angeles to dam certain of the waters in the Yosemite. Any of these proposed uses would not only destroy specific areas of much beauty and scientific interest, but would serve as an entering wedge in opening the parks to all kinds of commercial uses which would eventually undermine the entire National Park system. It is important that scientists make their wishes in this matter known in no uncertain way. BARRINGTON MOORE

PROFESSOR PAVLOV

TO THE EDITOR OF SCIENCE: Within the past few months Professor Pavlov came in for much comment on the pages of SCIENCE. Since most of the things that were brought to the attention of our scientific men were either based on mere hearsay or on second-hand information of the flimsiest sort, will you allow me the space to quote some direct news about Professor Pavlov.

H. G. Wells returned recently from a trip of inspection in Russia where he particularly investigated the condition of literary and scientific men. His extensive report has been just published by the New York Times.

they do has to go on in unheated laboratori is amazing that they do any work at all, y are getting work done.

Of Pavlov in particular he says: Pavlov is carrying on research of aston scope and ingenuity on the mentality of a ... Pavlov continues his marvelous resear an old coat and with his study piled up wi potatoes and carrots he grows in his spare t

It is gratifying to be assured that Pro Pavlov is raising potatoes only as a pa and still gives the best of his genius to tific investigation. S. MORGU

A QUESTION OF BIBLIOGRAPHY TO THE EDITOR OF SCIENCE: Regardin inquiry of Dr. Willey, Coues says on 50, in “Fur-bearing Animals”:

From this country [Mackenzie River re many accounts have reached me, from variou cers of the Hudson's Bay Company, throug liberality of the Smithsonian Institution, placed in my hands all the matter represent its archives upon the mammals of the far : ... Messrs. Kennicott, Macfarlane, Ross and hart have each recorded their experiences...

Therefore the following quotation Dall's "Alaska and its Resources," p. may be of interest.

Woiwodsky was succeeded by Furuhelm as Director of the colonies. The Kadisk was wr near Spruce Island. Robert Kennicott passe winter at Fort Yukon, where Mr. Lockhart w command.

In the annual report of the Smiths Institution for 1861, p. 60, it is stated "Mr. Ross, chief factor of the Mackenzie 1 district, has had the cooperation of the ge men resident at the different posts in district," among those mentioned is Mr. J Lockhart. He is mentioned in subsequen ports of the Smithsonian Institution, bu ways as James; never as J. G.

TO THE EDITOR OF SCIENCE: The Smithsonian Institution published in 1904, the collected "Researches in Helminthology and Parasitology" (1844-1891) by Joseph Leidy, M.D., LL.D. The issue was gratis, and is now out of print.

The writer has been applied to by a number of research laboratories in comparative pathology for reprints-he would be glad to know of any one to whom complimentary copies were presented, who would be disposed to donate any such, for use among those engaged in similar lines of investigation.

A SIMPLE DEVICE FOR GIVING ANESTHETICS

So often in giving anesthetics to an animal through the trachea cannula the student either covers the intake opening with several layers of gauze, or plugs the opening with absorbent cotton. To these he applies the anesthetic. When these substances are moistened, the air passages which exist between the fibers in the dry condition are almost wholly obliterated, and the animal is more likely to become asphyxiated than anesthetized. To prevent this almost universal failing I have devised a simple trachea cannula, adapted to both normal and artificial respiration and an appliance for anesthetization, which slips over the intake opening of the cannula.

The cannula consists of a metal T-tube, Fig. 1, C. In the long part a small tube extending the full length is soldered. At one end, I, all of the opening into the larger portion of this double-barreled tube is closed with solder. thus leaving only the smaller tube open, sm. This end is attached to the arti

The device for the administration of the anesthetic is made from a small hemispherical tea strainer (Fig. 1, 4). The opening of the strainer is soldered to a circular metal plate (B) with a hole (H) in the center, and a metal tube (E) soldered on the lower surface. This tube is large enough to easily slip over the side tube (D) of the cannula. One or two layers of gauze (G) are spread over the wire screens (8) of the strainer and fastened by passing a string or rubber band around the lower margin. The gauze, which can be readily replaced, is thus held away from the intake opening and permits of free passage of air and the thorough vaporization and mixing of the anesthetic with good air. In this manner a few drops of the anesthetic at a time are sufficient to keep the animal in complete anesthesia.
