opment of shock is given in the figure, which 

 illustrates the averages of the six experiments 

 which were carried out over a period of six 

 hours or more. 



From these results it is apparent that the 

 low blood pressure initiated by muscle injury 

 is not primarily due to a loss of vasomotor 

 tone or to a dilation of the blood vessels. There 

 is evidence'' that a continued low blood pressure 

 may ultimately result in an injury or depres- 

 sion of the vasomotor and other nerve centers, 

 and it is probable that this explains the dilation 

 of the peripheral vessels occurring some hours 

 after the development of shock.

THE LOUISIANA ENTOMOLOGICAL 

 SOCIETY 



This society has completed its second j^ear. 

 Starting early in 1920 with about 25 members, 

 it now has 36 memlsers. Including others who 

 have indicated their desire for membership, it 

 will have in 1922 at least 40 members. The 

 membership is distributed as follows: New 

 Orleans, 14; Baton Rouge, 11; Mound, La., 2; 

 Tallulah, La., 1; and others outside Louisiana 

 at various places from New York City to a 

 point in Mexico. 



Meetings have been held bi-monthly, except 

 during the summer, throughout the year. The 

 average attendance has been about 18. The 

 following papers and talks have been given: 



Work on malarial mosquitoes at Mound 

 Laboratory, D. L. Van Dine, U. S. Bureau of 

 Entomology. 



Beekeeping in Louisiana, E. C. Davis, 

 Louisiana Experiment Stations. 



Present status of cattle tick control in 

 Louisiana, W. H. Dalrymple, Lousiana State 

 University. 



The plant lice or aphids, Thos. H. Jones, 

 Louisiana Experiment Stations. 



The camphor scale, E. R. Barber, U. S. 

 Bureau of Entomology. 



Plant quarantine at the port of New Orleans, 

 Emile Kostal, Federal Horticultural Board.

moth borer- A. Comparison, T. E. Hollow at, 

 U. S. Bureau of Entomology. 



Entomological practice in Hawaii a dozen 

 years ago, Jacob Kotinskt, formerly of the 

 Hawaiian Experiment Station. 



The teaching of entomology, O. W. Rose- 

 wall, Louisiana State University. 



Two moving picture films, "The Most Won- 

 derful Insect in the World" and "Cotton's 

 Worst Enemy — The Pink Boll Worm," were 

 exhibited through courtesy of the U. S. De- 

 partment of Agriculture. 



The society is gradually acquiring an ento- 

 mological library, which is housed at the 

 Louisiana State Museum, Jackson Square, 

 New Orleans. There are now about 40 books 

 and about 500 pamphlets, largely the gift of 

 Mr. D. L. Van Dine, of the U. S. Entomo- 

 logical Laboratory, Mound, La. Through the 

 courtesy of Mr. Robert Glenk, curator, meet- 

 ings are held at the museum and the moving 

 picture projector is sometimes used. A very 

 successful meeting was held at Baton Rouge in 

 February, under the auspices of the members 

 there. 



Resolutions have been adopted during the 

 year on the camphor scale in New Orleans, on 

 financial assistance to the Division of Insects, 

 U. S. National Museum, and on the campaign 

 to control the Argentine ant in New Orleans. 



At a recent annual business meeting the 

 officers of 1921 were reelected for 1922. These 

 are : President, Mr. Ed. Foster ; Vice-president, 

 Professor 0. W. Rosewall; Secretary-Treas- 

 urer, Mr. T. E. Holloway; Executive Com- 

 mittee, the officers and Messrs. D. L. Van Dine, 

 Chas. E. Smith and Thos. H. Jones. 



The writer understands that certain members 

 of the national societies look askance at the 

 formation of local entomological societies, be- 

 lieving that these will draw members away 

 from the larger organizations and result in a 

 division of interest. This has not happened as 

 a result of the organization of the Louisiana 

 Entomological Society, and, on the contrary, 

 the interest in entomology has been stimulated 

 not only among entomologists but among other 

 students of biology.
