850 EXPERIMENT STATI02S' RECORD. 



The greater part of the work (pp. 17-129) is taken up by an annotated list 

 of 178 species known to inhabit or visit Porto Kico. The data include the 

 names by which the species is known, a brief account of its habits, and a 

 statement regarding its food and economic status. In some cases detailed 

 lists of insects and other animals, seeds, and fruits identified in the stomachs 

 are given in systematic order, so that as the status of other forms of life be- 

 comes known the relation of the birds to them may be more easily ascertained. 

 A bibliography of the literature relating to the ornithology of Porto Rico and 

 a subject index are appended.

Stryclinin sulphate. — Its effect on California valley quail, C. C. I'iebce and 

 M. T. Clegg (Pith. Health Rpt!<. [T. .S'.], 30 (1915). X<>. 50 pp. 3601-^604).— The 

 authors report experiments conducted which have been summarized as follows : 



" In each case convulsions and death occurred within a period of two hours 

 after administering the barley, and in each case the barley was reclaimed 

 from the pouch of the squirrel after death, showing, what had already been 

 proved, that strychnin is rapidly absorbed through the membranes of this 

 organ. 



" California valley quail may be fed, under natural conditions, relatively 

 large amounts of stryclniin sulphate without showing toxic symptoms. The 

 minimum lethal dose by subcutaneous injection is 4 mg. per 100 gm. of body 

 weight. The California ground .squirrel (CitcUus hcechci/i) is very susceptible 

 to strychnin sulphate; 0.00 mg. per 100 gm. of body weght pro<lucetl convulsions. 

 Nineteen grains of barley, containing 2.7 mg. of strychnin sulphate, when re- 

 tained in the pouch of the ground squirrel, proved fatal. Poisoned barley, 

 as used for ground squirrel eradication, does not cause the death of Cali- 

 fornia valley quail under natural feeding conditions."
