292 EXPEKIMENT STATION BECOKD. 



treated the author was able to note that on the day following the injection a 

 recession of from 0.4 to l.S° C. in the temperature took place and that the nasal 

 flow was checked, but 2 days later the temperature resumed its high level again, 

 the nasal secretion took on its original character, and the process in the glands 

 went on. 



Accessory thyroid tissue -within the pericardium of the dog, J. L. Swauts 

 and J. L. Thompson (Jour. Med. Research, 2// {1911), No. 2, pp. 299-308, pi. 

 1 ) . — In 21 of the 24 animals showing pericardial thyroids, the structure of these 

 bodies corresponded almost identically with the structure of the thyroid glands 

 of the same animal. The exceptions were two colloid goiter dogs and one 

 animal with hyperplastic thyroid, all of which showed normal pericardial 

 thyroids. 



In regard to the refraction of the dog's eye, R. Boden {Uber den Refrak- 

 tionszustand des Hundeauges. Inaxig. Diss., Univ. Bern, 1909, pp. 52, pi. 1, 

 figs. 4). — The eyes were examined of 100 dogs, consisting of various breeds 

 and ages, and of both sexes. 



The results show that the average dog is myopic, this being on the average 

 equivalent to 3 diopters. The limits found were from 1.5 to 6 diopters. The 

 various methods for determining the refraction of the eye are discussed, but 

 for dogs the author considers Schmidt-Rimpler's method to be the best. 



Bacillary white diarrhea of young chicks, L. F. Rettgeb (Abs. in Science, 

 n. ser., 33 {1911), No. 8-^9, i)p. 5-'/7, 5Ji8). — ^A continuation of investigations 

 previously noted (E. S. R., 22, p. 489). The author reports having found 

 Bacterium pullorum present in the ovary of a pullet less than 8 months of age 

 and one of the survivors of an infected flock, thus showing the laying hen to 

 be a bacterium carrier. 



On a possible cause of pneumo-enteritis in the red grouse (Lagopus 

 scoticus), H. B. Fantham and H. H. Smith {Proc. Zool. Soc. London, 1911, I, 

 pp. 46, -^7). — The authors state that of a lot of 40 grouse chicks 17 died between 

 the ages of 4 to 6 weeks, Upon examination the birds were found to be 

 suffering from coccidiosis, the parasites {Eimeria [Coccidium] avium) occur- 

 ring especially in the duodenum and ceca. As many of the young birds also 

 presented symptoms of pneumonia, the lungs, trachea, and bronchi of the 

 birds were carefully examined. 



Coccidian oocysts were found in the trachea, bronchi, and bronchioles. " In- 

 side these oocysts the processes of formation of the four sporoblasts were 

 sometimes found to be going en. The oocysts were probably acquired by the 

 mouth, and a few of them, instead of passing directly down the digestive 

 tract, as is usual, may have found their way, via the glottis, into the trachea 

 and bronchioles." 



RURAL ECONOMICS. 



Banking and its relations to our agricultural interests, J. R. Mulvane 

 {Bien. Rpt. Eans. Bd. Agr., 11 {1900-10), pp. 562-569).— In this address before 

 the board of directors of the Bank of Topeka, the president of the bank dis- 

 cusses the economic relations between banking and farming, showing their 

 interdependence and necessary correlation. 



Loans on improved agricultural lands {U. 8. Bouse Representatives, Hear- 

 ing Before Com. on Banking and Currency, 1911, pp. 8). — This is the report of 

 a hearing before the House Committee on Banking and Currency on a bill 

 authorizing a national banking association to make loans upon improved agri- 

 cultural land from " any portion of its funds not exceeding two-thirds of the 

 amount of its deposits not subject to check."
