.50ce, .75cc. Ice repeated twice, six doses for the whole treatment. 

 Of 35 people reporting for doses, only 20 reported with regularity 

 allowing tabulation, which was carefully done in detail to check 

 claims against actual results. A column of figures in percentages 

 shows actual findings. The summary gives several interesting points 

 of discussion. Here is a group of common colds, 25 in number, occur- 

 ring in an average college community, and from which were isolated 

 10 different organisms of varying pathogenicity. A polyvalent auto- 

 genous vaccine made up from these was found to be relatively non- 

 toxic in the dosage used in spite of the nature of some of them. In 

 treating these cases there was found to be no constant relationship 

 between the number of doses taken and freedom from colds during 

 the trial period of October to April, 2% getting absolute protection, 

 while 70% had one or more colds after the last dose, all living under 

 comparable conditions. This is true also for those cultured or not 

 cultured, suggesting little if any specificity for the vaccine. Over 

 half of those treated claim some benefit from its use, in reduced 

 severity of colds contracted and number expected, judging from 

 previous experience during these months. Not enough people took 

 the full six doses, making this group too small to draw conclusions 

 from. The attitude of the members of this group towards this vac- 

 cine trial is partially shown by 65% of them stating their prob- 

 able willingness to try something similar next winter. 



Some Intestinal Cestode and Nematode Parasites of Cats of Wake 

 Forest, N. C. R. B, Wilson. (Body of the paper accepted as a 

 thesis for the M. A. degree, 1922. ) 



The writer made at Wake Forest College an examination of the 

 intestines of 25 cats for Cestode and Nematode parasites. The report 

 gives an account of the material used and the method of study fol- 

 lowed. The result of the study can best be given in the form of a 

 table showing the relative number of each kind of parasite, as fol- 

 lows :

The unidentified nematode of the large intestine was very small, 

 measuring 320 to 432 microns in length by 10 to 19 microns in 

 thickness. These worms had the general appearance of larvae, but
