QUR ADVERTISERS. 
Reed and Carnrick present their well-known preparations 
of Malt and Beef Peptonoids. 
An analysis by Dr. Prescott, of the University, of their 
Maltine shows that it will convert 33 times its weight of starch, 
while the same preparation by the Trommer Co. converts less 
than half that amount. All our medical readers must be inter 
ested in the analysis of their Peptonoids, by Dr. Stutzer, of 
Bonn. Dr. Stutzer shows that there is more nourishment in a 
quarter of a pound of good steak than in half a gallon of beef 
tea made in the regular way. He then shows that 70 per cent. 
of the peptonoids consists of nitrogenous nutritive material, 
The conclusion follows that “ there is no food preparation that 
compares with it in nutritive properties.”

Particular attention is.called to the new advertisement of 
Prof. Sexton, announcing that he has sold his entire stock of

Gundlach will continue the manufacture of his excellent objec- 
tives and that somebody like Mr. Sexton will handle them. 
Mr. Bachrach and Bro., are offering some of the new em- 
bedding material, ‘‘ celloidine.” Being transparent, indestruct- 
ible, and non-shrinking it forms a most valuable medium for 
embedding small pieces of tissue of any kind. It is highly 
recommended for photo-micrography being free from sediment 
and highly sensitive.

AT THE DOCTOR’S EXPENSE. 
Young physician—* No, it is not in good taste for a young 
physician when writing to a patient to sign himself, ‘* Yours till 
death.” 
A local paper, in giving the usual graphic account of an 
accident which befell a hod-carrier, wound up by stating that
