摘要：

1. 1. Production of ammonia and urea by snails isolated singly for 24 hr at 25°C has been measured. In average values, snails weighing 225, 479, 1134 and 2480 mg (whole weight) have been found to produce 1·0, 1·2, 4·2 and 6·0 μmoles of ammonia respectively. Snails weighing 203, 479, 1134 and 2480 mg likewise produced 0·3, 0·4, 0·95 and 1·7 μmoles of urea in the same period. 2. 2. The rates of production (μmoles/g whole wt. per hr) of both ammonia and urea appear to be relatively constant over the approximate twelve-fold weight range indicated above (ammonia, 0·1-0·2 μmoles/g per hr; urea 0·03-0·06 μmole/g per hr.). © 1968.
