In anatomy he studied the circulation of the blood and the action of the eye. He made discoveries in meteorology and geology, learned the effect of the moon on the tides, foreshadowed modern conceptions of continent formation, and surmised the nature of fossil shells. His scheme for the canalization of rivers still has practical value and he probably devised the hydrometer.

解剖学方面，他对血液循环和眼有着较深入的研究；气象学和地理学方面，它也表现出了卓越的才华：他认为海洋的潮汐形成与月球的运动密切相关；他提出的陆地形成观念与现代理论颇为相似；他还还对化石的形成和成分进行了有根据的猜测；他设计并亲自主持修建的运河灌溉工程时至今日仍然有实际的应用价值，而在此过程中他可能设计出了液体比重计的雏形。

Under that, the miscellany began - a quadrant, a tin canikin, several sticks of tobacco, two brace of very handsome pistols, a piece of bar silver, an old Spanish watch and some other trinkets of little value and mostly of foreign make, a pair of compasses mounted with brass, and five or six curious West Indian shells.
