(15) In the enamel apatite suspensions, the apatite ion product altered with pH, which explained why apatite did not transform to brushite at pH 5-4.
(16) Similar results to those of series 1 were recorded but, in addition, calcium oxalate trihydrate (COT) precipitated in the pH range 3 to 6.5 and brushite at pH greater than 5.5.

(20) Of the brushite stones 61% appeared hyperdense on x-ray but they had no consistent shape.
Guano
Definition:
(n.) A substance found in great abundance on some coasts or islands frequented by sea fowls, and composed chiefly of their excrement. It is rich in phosphates and ammonia, and is used as a powerful fertilizer.
Example Sentences:

(13) "We're expanding fast," said one of the founders, Juan Andrés "Guano" Palese.
(14) This outbreak reveals that bats and bat guano are a source of histoplasmosis, suggests that only brief exposure is necessary for acute infection and reemphasizes that histoplasmosis is not confined to the midwestern states.
