Lithium induction of premature ovi‐position by the Japanese quail¹

Investigation supported by the Ontario Ministry of Agriculture and Food, and the National Research Council of Canada.

1. The intramuscular injection of LiCl into laying Japanese quail 6 or 12 h subsequent to an oviposition induced early oviposition of the next egg.

2. The shells of eggs from Li‐treated birds were without speckling and weighed half or less as much as shells from Na‐treated birds. Many eggs were also deficient in albumen.
