TRANSACTIONS OF SECTION P. fi33 



Young birds are much more susceptible to coccidiosis than older ones, but 

 older birds that have become chronics serve as reservoirs of oocysts and constant 

 sources of infection. In this connection infected foster-mothers of hand-reared 

 pheasants serve to infect young broods. 



Lime dressing of the soil, which destroys oocysts, is the most effective 

 treatment devised at present for combating coccidiosis. Either a little ferrous 

 sulphate, or a weak solution of catechu added to the drinking water is of service. 



All infected corpses should be burned and not buried, as oocysts remain 

 infective in the soil for long periods. 



S. First Results from the. Oxford Anthropometric Laboratory. 

 By Edgar Schuster, D.Se. 



The laboratory was started by Professor Bourne in January 1908, with the 

 following objects, among others :— (1) To obtain a statistical .survey of the physi- 

 cal development of undergraduates. (2) To ascertain what bodily changes or 

 developments take place during a man's residence in Oxford as an undergraduate, 

 and whether such changes depend at all on what, games he plays, what school 

 he reads for, and so on. 



The following measurements and tests are applied. (1) Acuity of vision ; 

 (2) spot pattern test. This test was devised by Dr. McDougall, and is intended 

 to measure the power of concentration. A pattern made by pricking nine holes 

 in a piece of cardboard is shown to the subject for a small fraction of a second 

 by means of an electric light placed behind it and a. photographic shutter. After 

 seeing the pattern five times in this way, he is asked to make a map of it on 

 squared paper. This he probably fails to do correctly; he is then shown the 

 pattern five times again and is asked to make a fresh "map; and so on until he 

 gets it right. Some interesting results have been obtained with this test, for it 

 has been found that the scholars and exhibitioners are distinctly better at it 

 than commoners; secondly, that men who subsequently took first and second 

 classes in the Final Schools were better than those who took lower classes; and, 

 thirdly, that men reading science and mathematics were, on the whole, better than 

 those reading other subjects. (3) Lung capacity, measured with a .spirometer. 

 (4) Stature, standing, sitting, and kneeling, from which are. deduced length of leg- 

 end length of thigh. (5) Weight. (6) Strength of pull; and also the following 

 head measurements : length, breadth, auricular height, horizontal circumference, 

 sagittal arc, transverse arc. 



In treating the material the men are divided into groups according to age, 

 and each age group is considered separately. The averages, standard deviations. 

 and various correlation coefficients have been found for each group. The strength 

 of pull and lung capacity increased considerably with age. Stature, weight, and 

 head length also show a similar tendency, but not to so marked an extent.
