attached to the front of the eye-piece of the Microscope by a piece of 
thin wood or a spring, and has its surface at an angle of about 45° with 
the plane of the anterior glass of the ocular. The image is thus pro- 
jected on to the paper beneath. No distortion will occur if the outer 
ring of light is perfectly circular. A dark cloth, such as photographers 
use, is thrown over the draughtsman’s head, and also the body of the 
Microscope, and all light excluded save that through the Microscope 
lenses. Any section can thus be easily, rapidly, and comfortably drawn, 
and accurate representations of objects magnified up to 500-600 
diameters can be obtained.” 
Walter H. Bulloch. — Mr. H. L. Tolman, President of the Illinois 
State Microscopical Society, communicates the following notice: — 
“ The death of Walter H. Bulloch, of Chicago, the eminent 
Microscope-maker, is a severe loss, not only to our Society, of 
which he was for nearly twenty years a prominent member, but 
to the cause of science at large, and a short sketch of his life and 
work will not be uninteresting. Mr. Bulloch was born in 1835, at 
Glasgow, Scotland, and lived there until lie was seventeen years of age. 
About 1852, the family emigrated to New York, where Walter learned 
the trade of tailor with his father. But his innate fondness for mechani- 
cal pursuits made him dissatisfied with his prospects, and he was 
apprenticed to Messrs. Pike and Sons, then a leading firm of opticians 
and instrument-makers, on Broadway, New York City. After serving 
his time, he went into business on his own account, until the war of the 
rebellion broke out, when he enlisted as a private in the 12th N.Y. 
Volunteers. His term of service, however, was very short, as he con- 
tracted a severe cold, which developed into rheumatism, incapacitating 
him from further work, so that he was mustered out of the service. 
Returning to New York, he formed a partnership with William Wales, 
the well-known maker of objectives, and continued in business there 
until 1866, when he moved to Chicago. He was very successful, .and had 
accumulated considerable means, when his shop and tools were destroyed 
in the memorable Chicago fire of October 8— 9th, 1871, and Mr. Bulloch 
sustained a financial loss from which he never recovered. Immediately 
after this misfortune he went to Boston, and was for a time connected 
with the late R. B. Tolies, but soon returned to Chicago. In 1888, he 
accepted a position in the Bureau of Weights and Measures, under the 
Government, but he chafed under the restraints of an official situation, 
and after six months’ experience returned to his home here. Before he 
left his health had begun to fail, and after his return late in the fall of 
1890, he suffered still more. But his indomitable perseverance led him 
to struggle on. He opened a place at 303, Dearborn Street, in a very 
advantageous business portion of the city, and began work again. It 
was not for long. After struggling with disease for about six months, 
he was compelled to stop work for ever. He died Nov. 5th, 1891. 
Mr. Bulloch was a man of pronounced character and indomitable 
energy and perseverance. To those who did not know him well, he 
appeared brusque and sometimes even overbearing, but his numerous 
friends soon learned to appreciate his straightforward manner of ex- 
pressing his views, his pertinacious but just demands for a proper 
recognition of his rights, and his outspoken criticism of what he
