DURING the coming summer a limited number of teachers of mathematics or astronomy will be permitted to spend a portion of their vacation at the Cincinnati Observatory, in the pursuit of studies connected with their special departments of instruction. Particular attention will be paid to the art of computing, in order to give an insight into the practical application of mathematics to astronomy. Opportunity will also be afforded to learn the use of instruments.
SIEGFRIED STEIN advocates the employment of rock-crystal for making normal standards of weight and measure, and other instruments of precision. The advantages of rock-crystal for these purposes consist in its indifference, at common temperature, to the action of acids and bases, or of atmospheric gases or moisture.
A NEW method of cleaning the skeletons of small animals, by utilizing the enormous appetites of tadpoles, is described in the English Mechanic. M. Lareste, the discoverer, has found that the tadpoles may be quickly habituated to a meat-diet, and that they rapidly denude the bones, when the carcass, previously skinned, is presented to them in water, kept in a warm and somewhat darkened place.

Brewer, at the Scientific School of Yale College, which it is to be hoped will before long appear in book-form. The topics discussed in these lectures are : “ Heredity,” “Atavism,” “ Close-Breeding,” “Crossing,” “ Relations of Animals to their Surroundings,” “Variation,” “Relations between Heredity and Variation,” “ Breeding to Points,” “ Limitations of Breeding to Points,” “Prenatal Influences,” “Relative Influence of Sire and Dam,” “ Crossing for Immediate Special Uses,” and “ Profitable Adaptation of Breeds to Special Localities and Conditions.”
DR. PHILIP P. CARPENTER, brother of the celebrated physiologist, William B. Carpenter, died in Montreal, May 24th. He was born in Bristol, England, in 1819, was educated at the University of Edinburgh, studied theology first, and preached awhile, and then gave himself up to natural history. He devoted himself to the mollusca, and gave a magnificent collection of shells to the British Museum. In 1859 he came to this country, and, selecting Montreal as his place of residence, went on with his scientific work till the failure of an English bank swept away his property, and he then took to teaching and sanitary reform. He gave a large collection of shells to McGill College, and was known as one of the best authorities on the classification of mollusca. He was a clever writer, a forcible speaker, and a man of refined Christian character.
PROF. E. S. MORSE, of Salem, sailed from San Francisco, June 1st, for Japan, whither he goes on a scientific mission of his own. He will spend the summer months in pursuing his favorite studies of natural history amid Japanese resources, and will devote especial attention to the animals of the coast, dredging a good deal, and carrying on the investigation of the Brachiopoda, which has long been his favorite line of inquiry. He will also make the trip subservient to gathering fresh materials for illustrating the “ Second Book of Zoology,” a text-book which he has begun to prepare. Prof. Morse will also, no doubt, gain much curious and interesting information to enrich the lectures which he will return in time to deliver before the lyceums next season.
