sea water, oysters could, nevertheless, be infecteil when exposed to conditions sim- 

 ilar to those of ordinary fattening. It is suggested, therefore, that the sale of fat- 

 tenetV oysters should be prohibited and greater care be exercised in preventing the 

 contamination of oysters with sewage. 



W. R. Blair presents a report on the diseases of animals in tlu' zoological park for 

 the year. During the year deaths occurred from pneumonia, gastro-enteritis, vari- 

 ous digestive disturl)ances, and intestinal parasites. The subject of cage paralysis 

 was studied by II. Brooks. It was found from a careful examination of a number 

 of ca.«es of this disease that the affection differs in different cases and is due to differ- 

 ent causes, as in similar affections in man. Most cases of cage paralysis are forms of 

 spinal paralysis of which the etiology is not well known. 



The internal parasites of wild animals received considerable study by W. R. Blair. 

 Notes are given on the morphology, life history, and means of eradicating a number 

 of such imrasites. The volume also contains articles on lizards, birds, manatee, 

 raccoon dog, and on the origin and relationship of the large mammals of North 

 America. 



Second report on economic zoology, F. V. Theobald {London: liritii^h 3fns. 

 {Xal. HiKt.), 1904, i>p. X |- 197, Ji^ix. '.."J). — As in the previous report of the author, 

 the insects and other animals discussed in this volume are classified according to the 

 manner in which they affect marH, animals, cultivated plants, and household mate-

 with especial reference to the best means for combating these pests. Notes are also 

 given on Stomoxys calcitrans and other insects affecting domestic animals. 



The author discusses sheep scab, ticks on poultry, lice on geese and pigs. Numer- 

 ous miscellaneous notes are also given on the insects injurious to cereals, legumes, 

 fruits, forest trees, garden vegetables, stored grain, food materials, tapestry, etc. 

 Mention is made of the value of pigs and poultry in destroying insects in orchards, 

 (.^uite elaborate accounts are presented of cabbage-root maggot, spruce aphis, goat 

 moth, and the insects injurious to wine corks.

Catalogue of living and fossil mammals, E. L. Trouessart {CaUdogus Mamma- 

 lium tarn Viventium quam Fossilium. Quinquennale Supplementum. Berlin: B. Fried-

 history of the rabbit pest in New South Wales with notes on the means which have 

 Ijeen adopted for exterminating these animals. It is reported that satisfactory results

The resistance of rats to arsenical poisoning, F. Bordas {Compt. Bend. Acad. 

 Sci. Paris, 138 {1904), Xo. 13, p. 836). — According to the author's experiments, rats 

 may withstand unusually large single doses of arsenic, but are especially susceptible 

 to repeated daily small doses. In some instances rats were destroyed by small doses 

 of arsenic before the total (juantity had reached an amount equal to single doses, 

 which were withstood without injurious effects,
