# Croune on the expansion of water beforeit freezes. Birch. IV. 26.

With Hooke’s objections, and Croune’s further experi-ments. Dated 27 Feb. 1684 .

Amontons on the effects of heat on air. A. P.1703. 101. II. 6.

Amontons assumes, that his thermometer is the naturalmeasure of absolute heat: Lambert and Dalton afterwardsadvanced nearly the same opinion.

Amontons on the apparent fall of the ther-mometer. A. P. 1703. 73. H. 4.

Hauksbee on the weight of water in differentrircumstauces. Ph. tr. 1708. XXVI. 93.221 .

Brook Taylor on the expansion of fluids inthe thermometer. Ph. tr. 1723. XXXII.291.

He found the expansion proportionate to the incrementsof heat by mixture.
