Emercio nullius videri poterat ob nimi am fluctuationem lucis Lunæ inter vapores. Die 29 Vesp. Luna obtegit Stellam Leonis Immersion sio fuit $9^h 27' 53''$ in recta cum Galilaeo, & Lansbergio. Emersio vero $10^h 24' 17''$ in recta cum Macrobio & Sofigene. *Mart.* die 21 Vesp. occultavit Luna Stellam $\gamma$ *Cancri*. Immersio fuit $8^h 14'$ in recta per Copernicum & Boreum marginem Langreni. Emersio fuit neglecta. *Maii* die 24 Summo Mane $1^h 51' 30''$ Luna absorbit Stellam $\tau$ *Scorpionis* proxime Byrgium. Emersio non fuit observata. *Sept.* die 14 Vesp. Luna occultavit Stellam $\eta$ *Capricorni*. Immersio fuit $8^h 11' 20''$ inter Seleucum & Cardanum. Emersio $9^h 37' 30''$ paulo infra Langrenum. Die 19 Vesp. Luna obtexit Stellam $\delta$ *Piscium*. Immersio fuit $8^h 43' 45''$ in recta per Tychonem & Langrenum. Emersio autem $9^h 5' 15''$ in recta cum Tychone & Keplero. *Oct.* die 28 Manè Luna occultavit Regulum, seu Cor Leonis Immersio fuit $1^h 39' 50''$ in recta per Aristarchum & Gassendum.

By a Letter from Dr. Fuller in Holland to the President, and communicated about October last, the Society was informed, that the ingenious Professor Ruyssch had observed something in the dissecting of Leaves analogous to the Veins and Arteries of Animals; but without explaining in what Manner these different Vessels were disposed, or by what Means they may be distinguished from each other.
